Part # CL200
The CL200 Inline Chlorinator is designed to automatically feed chlorine to your inground pool by working with your existing pump and filter system. Returning water to the pool flows through the chlorinator which is plumbed inline after the filter. A simple dial valve allows you to easily control the amount of chlorine being dispensed. No more floating chlorine dispensers in the pool or manually adding chlorine. The CL200 sanitizes your pool automatically, holding 9 lbs of Trichlor tablets or sticks. Hayward chlorinators are made from sturdy ABS thermoplastic and feature a durable Viton seal for the lid.
Flow Ratings: (GPM = Gallons Per Minute)
CL100 - Used with pumps with flow rating of 30-50 GPM
CL200 - Used with pumps with flow rating of 50-80 GPM
CL2002S - Used with pumps with flow rating of 50-90 GPM
CL110 - Used with pumps with flow rating of 30-50 GPM
CL220 - Used with pumps with flow rating of 50-90 GPM
Note:Chemical feeders should always be installed after a pool heater.
CAUTION: Extreme care must be excerised when adding chemicals to your pool. Concentrated chemicals may react violently if they mix in the chemical feeder, causing a fire or explosion, which may result in PROPERTY DAMAGE, PERSONAL INJURY or DEATH.
CAUTION: Never use any petroleum based lubricants on cover O-Ring. Regular lubrication is necessary to allow for easy cover removal. Use non-petroleum based lubricants such as Jack's No. 327 lube or Ivory bar soap.

I have a Hayward CL200. What do the numbers on the dial represent? Do they determine the flow rate of the chlorine tablets?
The dial on the chlorinator controls the flow of water through the valve and this controls the chlorine output. Lower numbers mean less chlorine and higher numbers mean more chlorine.
I have a plastic solar panel type heater. is it ok to use one of these units after the water comes out of the panel and before it goes into the pool? Thnaks.
Hi, Bill. I would not recommend you do without installing a check valve. Without one it will ruin your solar heater.
does this also work on an aboveground pool
Can I use bromine with this.
Hi. This unit cannot be used with bromine, you will need to use model # CL220BR.
Is there any information about the pressura that this chlorinator can handle? Thanks in advanced. Regards
Hello, the CL200 is used with pumps with flow rating of 50-80 GPM.
Dear inyopools, I have a CL200 chlorinator with and above ground pool. Is the chlorinator supposed to be full of water (with the tablets submerged)? I let the chlorinator fill with water, put the tablets and then close the lid. A few days later though I find it completely dry with no water inside, or just a tiny bit? Is my chlorinator faulty? My chlorinator is 3 ft below surface of the pool. Thanks in advance! Peter
Peter, That will depend on where the chlorinator is installed. if it is suspended above the ground, it is possible for the chlorinator to drain when the pump is turned off.
Is there available an in line check valve that can be installed in the black tubing of a Hayward CL220 off-line chlorine feeder? I know there is one built into the unit on the outlet side but I want another to prevent backflow on the inlet side. Where can I get it? Part number? Cost? Thanks!
Hi, Bruce. The Check Valve Inlet Fitting Assembly - CLX220EA is used with the CL220 Unit.
I have a 20,000 gallon inground pool with a haywood chlorine dispensor. I'm using 3" chlorine tablets. How do I know what number should I set the dial on? I read that he chlorine should be 1-3 ppm. Does that mean to fill the container and set it on 2? thank you
Perugini, Every pool is different. You will have to adjust the dial valve and monitor your chlorine readings. The number on the dial indicates how much or how little chlorine is being released to the pool. 0 would be the lowest setting and 10, the highest. I would say start off at 5 and adjust it from there.
Is a separate check valve needed for an offline chlorinator? Our second heater just failed again and the pool guys said we need a check valve but another said the chlorinator has valves in the already and they must have failed. Very expensive issue here. When shutting the pool off in the evening should we be turning the dial to zero to keep backflow from happening?
Hi, Chris. Installing an Inline Check Valve is required to prevent chlorine gas from backflowing into the heater. Turning off the control valve will not prevent backflow.
My pool is 26,000 gallons. I put 7 three inch tablets in the chlorinator. What number should I set the dial on the side to? Right now it is on full, Thank you.
Trudy, Every pool is different. I would recommend starting at 5 then adjusting up or down depending on what the chlorine reading is.
what is the chlorine consumption rate ? and when/how many times do i have to refill?
Hi. The chlorine consumption will vary depending on the pool water temperature, flow rate, and the dial setting.
I am ready to install the CL200 I bought but noticed that the CL200 really reduces the diameter of the water flow in the housing. Does this mean I will have problems running my fountains and circulation because it MUST BE reducing flow and build up pressure in the pipes due to the funnel effect.
Hi Rick, What you stated is true. I'm not a fan of Hayward's design, I personally like the Rainbow 320 Inline Chlorinator as it does not bottleneck down like the Hayward CL200.
I have a cl-200 chlorinator and it is 15 yrs old. when I fill it up the dial indicator set on 1/2 or completely off the chorine will all be used in a couple of days. What should I do to correct problem?
Hi. It sounds like the Control Knob - CLX200PA is no longer working properly and would need to be replaced.
WATER IS NOT GETTING INTO CHLORINATOR. THINK THAT IT IS CLOGGED WITH DE MATERIAL FROM FILTER. HOW CAN I CLEAN IT OUT OR UNCLOG IT?
Hello, depending on whether you have an offline or inline series you would need to flush your lines to see if it's something right before the chlorinator. If you have an offline series you can just get Maintenance Kit (clx220ga) to replace tubing that might be clogged or you can try and use a bristle brush to clear out any DE that could be caught in the tubing. If you have a Inline series, you might check the Tube, Feeder (clx200h) which is located in the chlorinator itself. To see all parts for the CL200.
The size of our pool is 1078 square meter and we will install 8 sets of pump with 170 gpm flow rate. Can we install 8 units of CL200 for each line?
Hello Cris, CL200 are supposed to be used with GPM 50-80 pumps. the highest is CL 220 or CL2002S which has a 50-90 GPM. So I would look at a few 300-29x types to handle optimal flow.
My cl200is leaking from the control valve. How do I take it a part ? Is there an "O" ring that needs to be replaced ?
Hello Lawrence, the knob you are looking for with orings is Knob,control Assembly W/o-ring (clx200pa)
My CL200 is installed on a system that has a temperature of about 180 deg. with around 50 GPM. the unit cracked on both sides of the dial. I was told is should be good for about 200 deg. do you think I just got a defected unit? Or recommend a different type.
Hello Jeff, I would contact Hayward 1800-657-2287 to make sure the temperature on the unit can withstand 180-200.
can I use this for my above ground pool
Hello, the CL200 can be used in a 32,500 gallon pool, also I would check your pump to see if you have a 30-50 GPM (gallons per minute).
I just had a new Hayward Chlorinator installed on my 9 year old poll. The pool is small about 20 x 12 and about 4.5 ' deep - maybe 7,000 gallons. What is the appropriate setting on the chlorinator? The technician set it at 5.5 but we notice a chlorine smell. My grandson complained about his eyes. Never had this problem with the original equipment.
Hey Bud,Thanks for contacting Inyo Pools, you would only need to set your chlorinator to the lowest setting; it should take care of all your needs with no chlorine smell and irritation to the eyes.
Is there a handel to remove the lid I have a hard time do to being old
Hi Dan, The Hayward Chlorinator Lid Wrench (DG31) can be used to remove the lid.
hi the water in my hayward chlorinator has turned a yellowish tinge and has an overpowering scent... also the water does not seem to be going back into the pool as fast anymore. I've cleared out all the tubes... what else can i do? i'm not sure the pool is getting adequate chlorine now
Hi Joe, You can try pouring hot water down the chlorinator to clean out any build up chlorine residue.
How many 3in tablets does it hold?
The CL200 Inline Hayward Chlorinator will hold approximately 9lbs, or 18 tablets. We always recommend that you use the correct number of tablets to adequately maintain chlorine levels in your pool.
Lid latch on my CL200, won,t line up with latch on the body of my CL200
Hi Martin, The o-ring might need to be replaced if the lid is not fastening down so that the lid locks into the latch.
I replaced a salt water system with a Cl200 chlorinator. Now the system seems to be very loud. Is there anything I can do to make system not as loud. Pump is quiet but the chlorinator is very loud,
The chlorinator should have little to no sound coming from it. You can try to make sure the lid and gasket are sealed properly and that you have no air in your lines. There are really no additional options for reducing the volume of a chlorinator.
I have a cl200 and have been using it for a little over a year and filled it with about 8 tablets and the setting between 4-6 but this year when it is filled and just set on 2 the chlorine gets higher than it is supposed to, so I just put in 2 tablets at a time could the setting indicator need fixed or a part for the adjustment need replaced or what can be done, I hope the answer is not a new chlorinator?
First, I would recommend that you use 1-3 tablets per 10,000 gallons in your pool. The more chlorine tablets you use, the stronger the concentration is administered. You have tried to pinch back the amount of chlorine, but what is being fed is super strong. I would try to find the right number of tablets, and then try setting it mid way. Then you have more flexibility to increase or decrease the amount of chlorine fed to your water.
I currently have a Hayward chlorinator installed using stabilized chlorine pucks. My CYA levels are off the chart. Can I replace the chlorinator with a new one and use non-stabilized chlorine pucks in the new chlorinator (to avoid adding even more stabilizer)?
Hello, The CL200 chlorinator is for use with slow dissolve tablets only. If you want to use "non-stabilized tablets", you would need to use a floating chlorinator.
If your pool doesn't have a separate chlorinator where do the chlorine tablets go?
You can use a chlorine float to sanitize your pool.
I am using this chlorinator on a large 20x50 pool. I am not sure it is large enough to keep it from greening up or if I am not using enough stabilizer and cyanuric acid. Seems I am using alot of shock each week also to keep it blue. Is this cl200 good enough for a 20x50 pool with a large 9ft deep end?
The chlorinator is large enough to handle your pool, with an approximate size of 34,000 gallons. You should be using at least 4-6 tablets every week to week and a half. Your stabilizer/CYA levels should be in a 30-50ppm range to hold the chlorine properly. If you have a current algae bloom, you will need to treat that with algaecide and shock before attempting to determine if your chlorinator is sufficient enough.
CL200. Trouble with holding chlorine in pools. Multiple Tests so far including phosphates are negative. If I disconnect the hose into return water is flowing so it appears to be functioning. Does this sound right? Would bad check valve somehow prevent chlorine to return ?
If the chlorine tablets are dissolving while in the chlorinator (1-1.5 weeks) and if water is flowing freely, then I would not think the check valve is the problem. Once we have determined the chlorinator is not the problem, I would look to a solution by having your water tested at a local pool store and ensuring that all levels are balanced and no algae is present.
Hi. Water isn't flowing thru my chlorinator. Any suggestions on how to clean it?
Hi Dave, You can clean out the chlorinator by pouring hot water down the chlorinator with the pump off.
Does the CL200 have any moving parts inside the unit, except the dial? How does the dial adjust the water flow? Can things get stuck and not allow change in water flow even if dial moves?
Hello, I would have to refer you to the manufacturer if you require specific information on how the chlorinator parts work (908-355-7995) but to try to answer your questions. The dial allows more chlorine rich water to be fed back to the pool. Commonly, there is a small check valve that allows water to enter the tablet chamber. The check valve can get "stuck", but there is not a piece you can access to "unstick" it. It is inside the bottom feed tube.
is this size the correct size for a 32,500 gallon pool? Filter is DE, pump is Hayward 50-80 gallon per minute.
Rand, Yes, this would be the correct size.
What do the numbers on the back of the chlorinator mean. How full should I fill the canister with 3 inch tablets.
Hi Kathie, If you're referring to the dial that indicates the amount of chlorine that the chlorinator dispenses. You can fill the chlorinator to capacity or put a couple which can last a few days or a week.
do you have the screw thaqt holds the cover together
The cover retaining screw is sold in a kit, Cover Ret. Screw W/ Slip Washers & Center Cap (clx200ega), that includes the washers and cap cover.
Do you need hoses for connecting the pump and hoses if you want to drain the water six foot away? Very new at this. Don't know anything about above ground pools. What all would I need to have the pool ready to used? From the liner to emptying the pool. Thank a bunch
Hello, Richard. The answers to your questions would take much more space than the Q&A section will allow, but fear not! We have a How To section dedicated to Above Ground Pools. You can click the link here, How to Guides, and the first option is Above Ground Pools. Hope this helps!
My fairly new CL200 in-line chlorinator (8 months actual working time) has been working well. Now, when I take the top off to put chlorine tablets in, I cannot get the top to screw all the way back down. I put a new O-ring in today, but it did not help. I could not get the top to make the last 1/2 turn, until it "clicks"! Any suggestions? (everything looks normal)
Hi Chet, You can try to lubricate the o-ring and make sure o-ring is installed correctly.
can't seem to get enough chlorine in my 15K gallon pool. just replaced the auto chlorinator - running it wide open, and also have 2 floaters full of 4" tabs. Cannot get the level up into the "good" range. Just recently had plaster removed and pebble-tech installed. Also replaced pump with a variable speed. Both done last fall - so water was also changed. Water is in good shape according to Leslie's testing. Any ideas? Chorine tabs are +1 yr old - can they go bad with age?
I understand that your water test from Leslie's says that the water is in good shape, but am I assuming you mean everything EXCEPT the chlorine is in good shape. That said, I will first ask if you are testing the water with both test strips and the drops? If not, then try both. Make sure your strips and reagents are under 1 year old. Second, you may need to shock the pool with either liquid or powder chlorine. Tablets are not shock, and an excessive use of tablets can result in high CYA numbers. Third, Yes, tablets can go bad. Tablets have an average shelf life of 1 year. Lastly, if you have had an algae bloom recently and have been fighting it, this can also cause a drop in the chlorine levels.
How can I disconnect a chlorinaator that is cracked and leaking. How do I disconnect from the water supply. Can not run pool bcause of the leak
Hello, Ultimately it depends on how the chlorinator is plumbed in. If it is not plumbed with unions, you will have to cut the pvc and replumb.
Can the hayward cl2002s be used for bromine.
The Hayward CL200 Chlorinator can also be used as a Brominator. Here is a link to the literature for the Hayward CL200 Chlorinator if you have additional questions.
I have an 18' above ground round pool with a Hayward EC40 pump / filter system. The system uses 1 1/2" ID Flexible pipe for it's plumbing. Which Hayward Chlorinator should I bet getting? the CL 100 or 110?
If your equipment hose is corrugated then I would use the CL100 and hose clamp the hose to a reducer fitting. If you have smooth hose then I would use the CL110 inline with the hose.
The faqs suggest I need 2 inline chlorinators for my 50,000 gallon pool. Will they work connected end to end, or do they need to be in parallel?
Hi Jared, The Hayward InLine Chlorinator (CL200) will have to be plumbed parallel.
I have a hard time getting the lid off
Hello Don, make sure the oring is lubed and cleaned on a regular bases. also there is a tool Lid Wrench (dg3-1) V that can be used
Where can I find a replacement o ring?
Good day. If you look here - The 200 Inline And Offline Series Parts. The o-ring for the lid is part number 2110-06 . It would be part #6 on the parts diagram.
One of your answers to a FAQ says "(make sure) the flow through the chlorinator is at that needed 50-90 gallons per minute" How do I do that?
I have a Hayward chlorine feeder that has worked well for a couple years. I just filled it today with 9-10 tabs as usual. When I turned on pump the chlorinator leaked out of top at 2 places. Can't get it to stop leaking. I noticed there is I-ring in the lid...does it require an O-ring? Thanks,
Hi John, You will need to replace the Lid O-ring (CLX200K).
how do i put the tablets in?
Cheri, remove the twist-off lid of the CL200 and then add the necessary amount of tablets for maintenance. For a full maintenance overview of the Hayward CL200 review Hayward's Owner's Manual
I would like to install a CL 200 for my 18,000 gallon in-ground pool. Is it safe to use with solar heating systems. Is there a special or different installation when using with solar heating panels.
Hi Jon, The Hayward InLine Chlorinator (CL200) can be used with solar heating panels. There isn't any special installation when using solar panels, but typical installation will require the chlorinator be plumbed in last as stated in the Hayward Chlorinator Manual.
On the outlet side of the chlorinator is there a check valve or anywhere on the chlorinator?
Hi Richard, The Hayward InLine Chlorinator (CL200) can only flow one way so that would indicate that it has a check valve within the chlorinator. However it does not show as a replacement part.
i have a Hayward Chlorinator cl220. I do not know if I have the flow correct. How do I know?
Randy, There should be an arrow on the body of the chlorinator that will show which way the water should be flowing.
my old cl-200 does not have a base I see your new ones come with a base I don't have much room is the base removable.
Unfortunately the CL-200 base is not removable. It is an integral part of the Chlorinator.
just boughT a cl 200 chlorinator from you guy`s .is there a video somewhere that i can watch for installing
Hi Birna. As of yet we do not have a vdeo of your style of inline chlorinator posted but we do have an instructional pictorial with written captions here. There are also many videos of an inline chlorinator install on Youtube. Thank you for your inquery.
can i use the hayward cl200 for a above ground pool my pool holds about 24,000 gallons of water
Yes you can use this for your pool. As long as you have sufficient gallons per minute flow and may need to either hard plumb this or use fittings that can be used to clamp or glue your flex hose to them.
how to open and add chlorine tablets
These lids uncrew turning it to the left. You can also use a special Hayward chlorinator lid wrench that you can view here.
JUST PURCHASED A HAYWARD SERIES CL200 AUTOMATIC CHLORINE FEEDER WITH 1.750 INCH FEMALE THREADED INPUT & OUTPUT INTERNAL THREADS. SO I AM PLANNING ON USING 1.750 THREADED TO 2 INCH SMOOTH FITTING ON BOTH ENDS TO REPLICATE THE 2 INCH PIPING I HAD ON MY PREVIOUS SANI KING PRO MAX 940 INLINE. MY RECTANGULAR POOL HOLDS 30K OF WATER AND THE OUTPUT SIDE IS 2 INCH SMOOTH. PLEASE ADVISE.
Hi Richard, You will need to get the Hayward Inline Chlorinator 2 Inch Slip (CL2002S), It has 2" slip ports.
what is the dimension from the inlet pipe to the outlet pipe?
These chlorinators are designed to be used with 1.5 inch plumbing for the female ports.
I have a 30,000 gal. in ground pool. Which chlorinator would go best with this pool? I'm having trouble keeping the pool stable by using the 1 skimmer basket to place the pucks in. I think it had a chlorinator on it at one time that someone has cut out and replaced with a 1-1/2" pvc pipe. Want to get the right one.
This chlorinator would be a very good option. As long as the flow through the chlorinator is at that needed 50-90 gallons per minute then it will work great. Also please be sure that the stabilizer and or also known as the cyanuric acid level is in par, for that will also aid in keeping the chlorine level stable.
I can't read the settings label its faded. How should the dial be? should it be up, right or left?
If you click on the main picture, it will enlarge and show you a better version of the label. If you look at it as a clock face - then 1:00 will be full open and 10:00 would be closed.
difference versus offline 220 chlorinator?
The only real difference between these models is that the CL200 is designed for inline use being plumbed in while the CL220 is for offline using flex tube clamped to the plumbing.
I just ordered a CL200, the two fittings to use for my flex hoses and a check valve. On the check valve, I know it goes prior to the chlorinator but as I have flex hoses and not rigid schedule 40 plumbing ( above ground 21x41 pool) how will the check valve mate up with the 1.5 inch flex hoses?
Jerry, You will have to use PVC for the check valve and then connect the flex hose to the PVC. The pressure will be to much for the flex hose going into the check valve, it may cause it to leak.
which unit should I use for my above ground 21x41 pool. The CL220 or another unit such as the NA342? I have flex hoses so I would need the adapters and check valve. Of the 2 units which one is your suggestion for me to order. Will the NA342 perform as well as the CL220?
Mr. Shannon,Both units will work on your pool. However, one of the major differences is the NA342 does not come with any hoses. It must be plumbed inline with the rest of your equipment. On the other hand, the CL220 is an offline unit and comes with all necessary tubing and clamps. The CL220 is sold more frequently.
After adding chloro tabs to my CL200 a couple of weeks ago, my chlorine rose to 10 ppm within 2 days when the dial was set to 2. The unit is about 5 yrs old and setting the dial to 2 usually keeps the Cl at 2-3 ppm. Over 10 days ago I set the dial to off and the ppm still hasn't gone down. The dial still stops when turned to off or full. Do I need to replace the dial or do I need a kit OR should I replace the CL200?
I have an above ground set up and use flex hose not rigid schedule 40 pipe. My pool is 21x41 oval. I have a 1.5 hp Hayward Power Flo Matrix pump. Which inline chlorinator model would I use and can I get the fittings to use the flex hose with.
Do I need the check valve to go with the Inline chlorinator for my above ground pool. The filter and pump are on ground level and under the water line.
Jerry, It is common practice to install a check valve before a chlorinator to keep the more concetrated chlorine from backing up into the filter and pump when the pump is shut off.
I have a 21x41 above ground pool. Completely decked in. If installing a inline unit, do I need a check valve in place as well? The unit will be under the deck but below the water level of the pool.
Jerry, A check valve is required to protect chlorine from back flowing into your heater or filter, whichever one you have installed before the chlorinator.
I just replaced my Hayward Chlorinator with a new one, same model, CL200. I installed new lines and fittings that came with it. I have two questions. First, the Chlorinator is not completely filling with water...maybe 1/2 full. Why? Second, with 7 tablets in the Chlorinator, and the adjustment set to the maximum, and my chlorine readings are constantly low (.1). Why would it not be reading quite high, and then require me to reduce the setting. Same problem with the old one. Thanks for your help.
Allan, It is common for the chlorinator to remain half empty. When you first put the tablets in, it will take a few days for you to get a chlorine reading since they are slow dissolve tabs. You can try shocking the pool when you first put in the tabs to get a chlorine reading.
Chlorinator feeder has a small chip that seems to be leaking.This is at the lid top. Can this be fixed or do we need a new chlorinator? Thanks Already have new o-ring.
Hi Michelle, You could just replace your Hayward CL200 Cover here.
My Hayward Chlorinator no longer dissolves the salt tablets. To me this means the water flow is bypassing the salt storage area. Is this a simple fix (e.g. cleaning debris out of the intake) or do I need to replace the unit?
Mark, You can try cleaning out the chlorinator by pouring hot water down the chlorinator. If that doesn't work then replacing the chlorinator will be your next option.
I pump untreated 'spring water through a sediment filter, then into a 1,500 gal storage tank. Can I add your chlorinator to the 1 1/2 inch line going INT0 the storage tank, immediately after the sediment filter? From storage, water goes to a 'pressure tank' and through two 'whole house' carbon filters BEF0RE branching off for use by my family. Is your chlorinator 'adjustable' to our water’s 'chlorine' needs, if any? We test water weekly. Thanks,
Wallis, Unfortunately we can not recommend this product for anything other than pool use. I would recommend calling Hayward to answer yoru question. You can reach them at 888-429-9273.
Correct way to hook up hoses for in and out output on the chlorinator to filter and pool pump
Hi Jackie, Pages 4 - 5 of the Hayward Chlorinator Installation Guide show the proper steps for installation.
I have a pump that has MAXIMUM CAPACITY (at 35' Head): 86 GPM FLOW AT 50' HEAD: 60 GPM with 1 1/2 pipe size pipe. Is this the correct model for me?
I would recommend the Rainbow 320 Chlorinator as it has much less flow restriction than the Hayward CL200 chlorinator.
I have an 18x36 in-ground chlorine pool with an inline chlorinator that was installed when pool was constructed in 1997. Haywayd system, screw off lid with drop in tablets. Dial it in and leave it. I still do the weekly check and treatments if necessary but my question is: I have been told that an inline chlorinator can only be used on saltwater pools. Please respond with information.
Kathy, In-line chlorinator are made for customers who uses chlorine tablets to chlorinate their pool. Saltwater pool wouldn't need an in-line chlorinator because the chlorine is generated with a saltwater system.
Have 2 inch piping through whole system with water features. 55 gpm pump, cartridge filter. Would putting this in create a restriction dropping to 1 1/2 pipe? Would I be better off with a off line? I'm replacing a pentair salt chlorinator and did not know if would be same unions. Can you give thread dimensions? Thank you in advance.
Yes putting the Hayward CL200 on 2" plumbing would cause a bit of a flow restriction as if you look through the 1-1/2" port it actually bottle-necks down to about 3/4" at its narrowest point. The offline version does have some issues with the tubes getting clogged. I would suggest the Rainbow 320 Inline chlorinator as it is a straight 2" port and has minimal to no flow restriction on 2" plumbing.
I am putting in a small in ground fiberglass pool, +/- 2500 gals and I am installing a 40 watt uv sanitizer and an ionizer. I understand I will still need to add a small amount of chlorine, equivalent to tap water. Is the lowest setting low enough for this application?
Bruce - The CL200 , set on the lowest setting, may produce too much chlorine for your application. We would recommend the Rainbow 320. The 320 has the option to add a spa chamber which allows you to lower the chlorine output by using smaller tabs.
I have a 33ft round above ground pool (27,500 gal) with flex hoses. Will this work or do you recommend something else?
Hello John - The CL200 will work on your pool. We would recommend purchasing two adapters for the flex hoses.
Can you use Cal hypo tablets in this clorinator if inside pool(Cl-200)
Mike, Unfortunately you can not use cal-hypo tablets in this chlorinator. It is designed for sloq dissolve tablets only.
I have a Hayward inline chlorinator now and for approx 10 years. For the past 4-5 years we have difficulty unscrewing the top off to add the chlorine and to the point i can no longer add the chlorine myself. I need to ask someone else to do it and it is difficult for them as well. We would like to replace the chlorinator but afraid to get this same model with a screw top as we may have the same difficulty. Does Hayward sell a latch-on type lid rather than a screw-on type?
Unfortunately Hayward has not changed the design. The best way to prevent this from recurring is to keep the lid o-ring lubricated and to use the lid wrench - Part number 0211-0 or click on this link - http://www.inyopools.com/Products/07501352020738.htm#parts
I am thinking of purchasing a chlorinator, I use flex hoses right now. Will I have to change to solid piping?
You can use flex pvc or hose to plumb in the chlorinator. Keep in mind that both will deteriorate at a faster pace vs hard pvc and will need to be replaced eventually.
Does this model work for above ground pools?
The CL200 will work well with an above ground pool if the plumbing is hard pvc. We offer the NA342 for above ground pools with flexible plumbing.
Does the Hayward CL200 need an external check valve?
Generally, yes, It is a good practice to keep the water with high concentrations of chlorine from backing up into your heater or filter.
I have a really hard time taking the cap off my chlorinator. Is there a wrench that I can buy?
If you are having difficulty removing the lid on your Hayward CL200 or CL220, you can the Dura Grip Lid Wrench: http://www.inyopools.com/Products/07501352020738.htm#parts It fits securely on the lid, making removal a breeze.
What is the difference between an inline and offline chlorinator?
An inline chlorinator would be plumbed directly inline with the plumbing. For an existing pool, this would mean a section of pipe would need to be cut out to install the chlorinator. An offline chlorinator attaches to existing plumbing by chlorinator tubing (holes would be drilled into existing pipe to attach the tubing.)
How do I know if one chlorinator is enough for my pool?
The Hayward CL200 or CL220 chlorinator will provide enough chlorine for up to 40,000 gallons of water. You would need to calculate the volume of your pool to determine how many chlorinators you would need. For example, if you have 60,000 gallons then you would use two CL200 or CL220 chlorinators.
Does the in-line chlorinator come with a check valve, or must it be purchased separately?
No this does not come with the check valve. We would highly reccommend purchasing one of the check valves listed on this page http://www.inyopools.com/valves_flo_check.aspx
Is there a feedback mechanism that tells the unit the chlorine balance in the pool? Is this a way for me to automate addition of clorine to keep it always at the correct level? Or, just another place to put the tab aside from the the drain basket?
There is a dial on this unit which has a setting from 1-10 If you set the dial on 1 it will be letting the least amount of chlorine to the pool and if you have it set at 10 this would send the most amount of chlorine to the pool. So you can automate the feed of chlorine to the pool but you will still need to manually test your water. We do not recommend placing tablets in the skimmer basket because this high concentration of chlorine goes directly back to your pump and can cause corrosion to your pool equipment. If you do not go with the automatic chlorinator we would recommend at least going with one of our floating chlorinators so you do not damage your equipment you may view our floating chlorinators here http://www.inyopools.com/chlorinators_floating.aspx
Can I use granular, or must I use 3" tablets or stick?
We recommend using tablets or sticks, and not to use granular with chlorinators.
Does this model work with 1 1/2" PVC?
Yes this is made for 1 1/2" PVC pipe.

There were more than one models to choose from. I had information for the original chlorinator. For new, I found the one which exactly match the dimension. Replacement was pretty simple. Stop the pump if it running. Just unscrew the unions on each side of the existing chlorinator. Remove the existing chlorinator. Wrap the male threads with white Teflon tape. Hand tighten each union. Start the pump and check for any leak. In my case hand tightening was good enough to make the connections leak tight. Did not need to tighten any more with wrench. Thanks INYO for sending me the right part and good instructions. Weather is nice and warm today. Buy. I am going to jump in my pool.
(5 out of 5 stars) Great Chlorinator

Pros: Makes keeping the chlorine level in your pool easy and trouble free.
Cons: You must be careful when putting tablets in the chlorinator as the chlorine smell is very strong.
This CL200 Hayward chlorinator was a replacement for my 12 year old Chlorinator, which I cracked by accident. The new chlorinator works very well and is a duplicate of the old one, but shinier. Works well, lasts a long time. Get the union kit to ease installation now and in the future.
