When should I change the sand in my filter?
Reply
You should change the sand in your filter every 5-7 years. You can generally tell that it is time if your pool water is not as clear as it normally is or when you notice the interval between backwashes is shorter. You can use > this guide to walk you through it.

How often do I have to replace the sand in my filter? What is normal operating pressure?
Reply
On a "fresh start-up" a filter would operate anywhere between 10-20 psi. As a general rule of thumb you only want to backwash when the pressure increases 8-10 psi. You want to make certain that the pump is being turned off whenever you move the handle on the valve. Once backwashing is complete (3-5 minutes), you can switch to the rinse option to re-settle the sand bed. Sand will typically last 5-7 years. Premature backwashing will wear down the size of the sand which will cause difficulties such as cloudy water and higher operating pressures.

My back wash and water return flow is very weak. Also after back washing there is sand being sent back into pool in return flow.

Hi Bonie, If you are getting sand back in the pool then I would check out this article on Getting Sand Back in Your Pool as it goes through common items to check when getting sand back in your pool.

I have a 24 foot round pool. I need a new housing for my Sand filter. It is a fiberglass tank and has started to leak. The model is a TA35/35D. Can you give me a price. Ty.

Unfortunately we do not carry the TA35 tank as it costs more than the complete Tagelus filter. The TA35 Tagelus was replaced by the TA40 Tagelus Filter here.

What size sand filter is required for a 12,000 gallon in-ground pool running on a 1.5 HP pump? Looking at the Hayward S244T. Would you recommend this, or a different Hayward model?

Hello, The S220T would be ideal for your pool size/application.

April, The replacement Label Plate (SPX0710G) will work on all the Hayward Multiport Vari-Flo 1-1/2" SP-710X, SP-712, SP-711 1976-Current

Our S220T is about 12 years old and we need to change the sand, it doesn't appear that unions were used in the PVC install, is there anyway to remove the multiport valve to change the sand without cutting through the PVC? I'm wondering if the PVC is screwed into the pipe and can be unscrewed.
Reply
Unfortunately it is very unlikely that you can remove the multiport valve from the filter without needing to cut the pvc. The positive out of it though is that this gives you an opportunity to install those unions so this will be very easy in the future.

My 15 x 30 by 4.5 (ave) pool has about 47 feet of head. I'm interested in a 2" inlet pump and the Pentair .5 HP seems to be adequate. Can you please double check me (in case I need larger, I have 120V at pump. The only 'feature' I have is the Kreepy Krawler, but I included the hose length in the head calculation. I also want a recommendation on a filter (prefer Pentair also) that is NOT cartridge. Something that requires even less maintenance. I also have a Salt Chlorinator. Thanks! Pete
Reply
Hi Pete, you probably could get by with the 1/2 Horse Power (HP) pump but my concern is having enough suction to power the automatic pool cleaner, for this reason I would suggest the 3/4 HP Pentair Whisperflo Pump. The Whisperflo pump has 2" ports and is classified as an energy efficient pump. If you are looking for easy maintenance then I would go with a sand filter, in my opinion sand filters are the easiest to maintain. If you go with the 3/4 HP pump then I would pair it with the Pentair Sand Dollar SD80 Sand Filter. Both the Whisperflo pump and Sand Dollar filter will work fine a salt system.

I have a 18 x 36 inground pool running a 1hp Super pump and a Laser 250L that has developed a split in the tank and needs to be replaced. I am looking for recomendations on sizing and Brand of Sand Filter replacement. My pool due to repairs done by prior owners has only one intake 1 1/2" (Skimmer) and one return line which was cut down to a 1" line for some prior repair reasons ( I assume failure to properly winterize).

Hi, The Hayward 22 Inch Tank Top Mount Sand Filter (S220T) would be suitable replacement for your current unit. I would recommend going to the Hayward 24 Inch Tank Top Mount Sand Filter (S244T). I would offer you better water flow and less cleaning/backwashing.

The height of the filter does that include the multiport or not in the measurement.
Thx,

Hi y'all!
Started my question but I touched something accidently so not sure if it got thru.anyway, I have a Hayward S220T with vari-flo XL valve(Model SP714T1). Last year when back washing sand was in the waste water. Could it be a gasket in the valve? Will be opening it soon and thought it best to take care of the problem now. Many thanks!! Dee
Reply
Yes, sounds like a bad spider gasket. That gasket is not sold separately so you can either get part number 4703-20, which is the key, cover, and handle assembly, or part number 4703-23, which is the key assembly with the spider gasket.

This 22" Hayward sand filter would be a great fit for the 1.5 HP Pentair Optiflo and this pump and filter would be the correct size for a 15' x 30' x 48" above ground pool.

Is just guessing game or could I need to get a new filter and if so...same one since pipes will fit??? HELP
Reply
You should not have to replace the filter, if the sand has not been replaced in a while I would recommend changing that out though. Otherwise, it sounds like they are not circulating your water long enough and not keeping enough chlorine in your pool. The water will turn green when there is not enough chlorine in the pool.

are the flanges on the tanks all the same and can a Hayward valve fit any sand tank

No the flanges on the tanks are not all the same and the valves only fit the specific tanks they are designed for. If you supply us with your filter or valve information then we can suggest the appropriate counterpart.

Have Hayward S220T Sand Filter. My pool has been staying cloudy recently. Did everything pool store told me still not clearing up. Color is ok can't see bottom in deep end. Do I need to change sand in filter? What kind of sand should I be pouring into water return? Been using DE but we don't have a DE Filtet. Usually when I backwash the water in the sight glass will cloud up and turn clear, but now it is only clear and when I backwash now the water coming out is clear with no sand. Please help!
Reply
Hi, Andy. If the sand is more than 3-4 years old I would recommend replacing it. Poor filtration can cause the pool not to clear up.

What is the maximum safe operating pressure (OP) of the 220T? This is a fresh install with 150lbs #20 sand + 50lbs Zeosand Alternative. After backwash & rinse, OP = 22psi. Upon adding the new Barracuda G3 to dedicated cleaner port, OP increased to 30psi with fresh, clean sand. If dirty sand increases pressure 8-10psi, that will put the OP at 40psi. Is that within the safe operating range for this filter unit? I ask, because my last unit exploded/ruptured due to over pressurization. Thanks!
Reply
Hi, Jason. The max operating pressure of this filter is 50 PSI. Using two different type of sand is the cause of what you're experiencing.

I have a 16 x 32 inground pool with a Hayward S-220T filter and a Haywood Max-Flo II pump 1-1/2 hp. The return going to the pump has very little suction although the return to the pool seems to be strong. Line to filter has been replaced, so it is not constricted anywhere. Am I using correct pump size or could I need a new pump.

Jean, The pump would be adequate for the pool and filter size. If you have a main drain, I would recommend closing it and drawing all suction from the skimmer. You may have air trapped in the line.

we just bought a home with an in ground pool the seller had no info , we have the pump running and the water chemicals are at normal numbers now. The pool had not been covered or cleaned all winter .We have removed all the debris in the pool but now we can not clear up the water its cloudy. We have not been able to see the bottom at all .we have no idea when the sand was replaced in the filter . could this be our problem not being able to get the water cleared up?
Reply
This can be the cause of the cloudiness or even any organic material on the floor of the pool. Sand filters sometimes have difficulty filtering that sort of material. If the waste line is set up well for discharging water then maybe consider vacuuming that material to waste to assist in getting that out first allowing the filter to grab only whats in suspense in the water.

Have a 2 horse power pump, what size Filter would I need to run a 20,000 gallon inground pool?

Hi. The filter size will be based on the flow rate of the pump. To determine the flow rate of your pump, you will need to calculate the Total Dynamic Head (TDH), then use steps in our How to Size a Pool Pump for Your In-Ground Pool and How To Size a Pool Filter to determine what size filter you'll need.

Does this S-220T contain everything pictured? It seems cheaper to replace the entire unit if you have a lot of issues with the one you have. I have this S-220T already and sand is coming through into my pool. My initial assumption based on everything i read is to change the laterals.
Reply
Yes, this filter comes with everything in the images on its product page. Usually, the sand returning to the pull is due to bad laterals or spider gasket in the valve. Especially if the pump used with it is the original that came with the system upon install.
