This guide describes the steps required to install a Hayward sand filter. The picture at left shows the two major components of a typical sand filter: the Filter Tank and the Multiport Valve and piping assembly. When installed, the valve sets on top of the tank and the vertical pipe the lateral assembly are inside the tank.

skimmer blow out - I need to understand your problem better. Where is the water getting sucked in? And, when you say the water is "blown out through the skimmer", is it flowing backwards from the filter through the pump to the skimmer?Reply

I have above ground pool everything is hooked up correctly water getting sucked in and blown out though skimmer/Reply

Martin - Not sure what you mean by maxed out. If it's operating at around 30 psi with new sand, your pump may be too powerful for that filter. If you have to downsize the pump, the cheapest thing to do is to replace the current impeller with the next smaller size.Reply
Martin Posted: 5/29/2016
I have installed as above and our pressure on the filter is maxed out. Do you have any suggestions?Reply

LEROY - We recommend changing the sand in your filter every 5-7 years. See our guide on "How To Change Sand In a Sand Filter".Reply

HOW OFTEN DO YOU GOT TO CHANGE THE SAND OUT IN THE FILTERReply

new filter - Most people run their filters 8-10 hours a day during the swimming season.Reply

how long do I run my filter for after installing a new sand filter?Reply
InyoPools Product Specialist Dennis R. Posted: 7/9/2015
filter before pump - There would be at least three problems with putting the filter before the pump. First, any debris that would normally be collected in the strainer bucket would go directly into your filter and second, you probably would not be able to prime you pump. The filter tank would have to be completely full of water before the pump could suck water into the front end of the pump. Then you would also have the problem of how to direct the water to the desired function after the pump: waste, filter, backwash, etc.Reply
John Posted: 7/8/2015
Is it possible to install the sand filter before the pump or suction side? If not, what is the reason? Thanks..Reply
InyoPools Product Specialist Dennis R. Posted: 6/23/2015
Filter base - The filter should be installed on a level and stable base to operate properly. Also when it starts to tip, you will be putting extra strain on the connecting piping and other equipment.Reply

Can you put a silica sand filter directly on ground or is it better to place on a base? By putting directly on ground will it eroid faster and will it get tippy when water is drained out in winter?Reply

Cyn - If you are referring to the label on top of the multiport valve, there is a good picture of it on this product site: Hayward Multiport Variflo XL 1 1/2" SP714T. Click on the smaller label picture at the top right. The handle is partially covering the “Recirculation” mode.Reply

Don - It sounds like you may be getting air into your system through a air leak in the suction side of your pump. Check all the connections between the pool skimmer and the pump. See our guide on "How to Identify and Correct Air Leaks" for further information.Reply

When we run the pump there is a gurgling noise coming from the filter any ideas its a 22" sand pump & filter by waterway?Reply

ciocca77 - Generally the ports on a small to medium filter are 1 1/2", but they can be 1 1/4" on an above ground pool filter. Measure the inside diameter of the port fitting to be sure.Reply
ciocca77 Posted: 9/11/2014
I wanna hard pipe my sand filter also, is that 1.5 or 1.25 inch pvc pipe glued into the fittings that thread into the filter? Any help is greatly appreciated. ThanxReply
InyoPools Product Specialist Dennis R. Posted: 8/10/2014
Jim - I'm sorry but we don't have a diagram on you filter. Generally the free end of the air release tube is placed at the top of the tank in the space between the sand and the top of the tank. I suggest calling the manufacturer for more specific directions.Reply
Jim Posted: 8/9/2014
Your install directions are the closest I've found to match my unit from blue devil. As a top mounted multiport valve, directions do not tell me how the air release tube is installed which is coming from the base of the laterals. Any help would be appreciated thanks in advance.Reply

Tamara - If your multiport valve is set on "Waste" while you are filling your pool, move it to "Filter". If the valve is not on "Waste", you probably have a damaged spider valve in the multiport valve that is letting water out the Waste line. To replace this gasket see our guide on "How to Replace a Spider Gasket on a Multiport Valve".Reply
Tamara Posted: 7/30/2014
I'm filling my pool for the first time and I get the water to skimmer level and I keep losing it out the waste line on the filter. Should I have my filter on closed to fill the pool? HelpReply

Laterals - I don't really understand your question. Are you trying to get the laterals out of the tank? Depending on the make of your sand filter, some laterals rotate up from the hub as shown here while other are individually screwed out of the hub.Reply
Anonymous Posted: 7/12/2014
I have a sand filter I need to put the sand back in. The laterals don't bend. Is there a easy way to to do this?Reply

Pool boy - If you lost prime when you were vacuuming, you may have a leak in your vacuuming line. Can you shut that line off and try priming with only the regular filtering line open? Fill the pump for 5 minutes to get water back in the suction line. Also, if you had a lot of debris in your pool that went into a cartridge filter, you should clean that out good. If you have a sand filter, try replacing the top 6" of sand to get some flow so you can backwash 2-3 times.Reply
Pool boy Posted: 7/6/2014
I just hooked up a gifted Hayward pump filter, short of a few leaks I had great success. Before turning it off for the night I decided to vacuum the pool. Doing so I lost my prime-I proceeded to run through the start up procedure again, my hope is I didn't plug the system it will not fill with water. Any quick fix ideas??Reply

Dougjonz - For the Hayward S180T filter shown in this guide, the filter discharge port connects to a 1 1/2" PVC pipe, the larger filter will connect to 2" pipes.Reply
Dougjonz Posted: 7/1/2014
Do you happen to know the size of the pipe connected to the filter discharge? Is it 1.5" PVCReply

danny - These drain caps usually come with an O-ring. Did you inspect and replace the O-ring? And if it still leaks, try wrapping 3-4 layers of plumber tape around the drain port threads.Reply
danny Posted: 6/21/2014
I installed a new screen and drain cap on my hayward sand filter. I tightened it as tight as I could but could not stop it from leaking. Any suggestions?Reply

Newhouse-oldpool - See our guide on "How To Go From Cloudy To A Crystal Clear Pool" for a possible solution for your cloudy water. And your can put a small amount of DE in the filter now.Reply
Newhouse-oldpool Posted: 6/13/2014
Thanks for the quick response. Regardin the flakiness-- that is all gone. Only when i first brushed/vac'd the pool did i see flakes. Its as if it all dissolved now, as i do not see any debris floating- just very cloudy water. No change after the filter ran three days straight. pH,alk, and chlorine levels were good when we tested water two days ago at local pool store. I also have a solar cover on top all week so there is no new debris falling in.... So whatever it is is just not filtering out even with new sand. Sand when i checked in old pump did have larger old debri in it though (even after several, prbably too many, backwashes). I was going go with zeolite filter media this time instead of sand... Can i add cellulose or a small amount of DE rigt away or should i give several days of running before adding any extras to filter?My bags of shock i believe have tri-chlor.. Should i put a different type of shock in when i shock for this weekend?

Newhouse-oldpool - The "white flakyness" may still be in your filter and is recirulating. This should be solved with the new pump and filter but you may have to backwash 2-3 times. If there is no Rinse setting, you would Backwash then go to Filter. Recirculate just bypasses the filter. Waste also bypasses the filter. See our guide on "How a Multiport Valve Operates".Reply
Newhouse-oldpool Posted: 6/12/2014
We bought a new house last year. Swamp green pool. Got the water to a cloudy blue before closing for winter. Opened a couple weeks ago and everything settled to bottom - white flakyness when I brushed it (should have vac'd to waste but didnt know). Now water is very cloudy. Got chemicals to good levels and ran filter for at least 3 days straight and change. What could be wrong? I also tried some clarifier and it did nothing.Notes: 10,0000 above ground gallon pool. Good flow, new sand, old filter and pump. 4 setting valvle (no rinse). I forgot to backwash initially when first running with the new sand..
(We order an entirely new filter+pump which arrives tomorrow -- if there is no rinse setting -- should I backwash and then go straight to filter? Or Recirculate? Or waste and THEN Filter?)
Sorry for so many questions. New to this!!

soap suds - Try backwashing and rinsing the filter 2-3 times in a row to clear whatever has collected in the new sand.Reply
Anonymous Posted: 6/9/2014
Hope you can help. Just opened the above ground pool, new sand in filter. But there is a white film. like soap suds coming out of the filter. It was there before putting in chemicals. What have I done wrong?Reply

Trouble in Florida - If you have good water flow, it sounds like you have to replace your pressure gauge.Reply
Trouble in Florida Posted: 5/28/2014
I just changed out the and three weeks ago and just noticed that the pressure indicator is showing 0 psi still. I backwashed it and a bunch of junk came out but it still shows 0 psi. Is this normal or could it be a bad indicator? ThanksReply
