You can try different epoxy's but they usually won't hold as the filter expands when running this will break any seal where you put it.You can check into warrentys. A lot of these filters had good warrentys on the tanks that went longer than valve or internal's. if you have install dates and model #'s. Check on line with Hayward.

Worse comes to worse you can drill out a small hole amd using stanless steel go with a bolt and nut with washers and rubber washers in the middle. when you set it seal it all with silicone and after it is tight let it set for eight hours or so. Good luck.

How do I fix a pin hole leak at the seam on a Hayward S369SX? What type of glue?

Hello, i just had a 3/4 inch open area develop close to the bottom of my sand filter. Apparantly the base rubbed it raw and the water was leaking like crazy. We called the pool place and they said they have never been successful in repairing a seam. Well we looked it up on the internet and there did not seem to be any real good solutions. . Our friend Ryan came over and he is an auto body man. he brought a tube of plio grip by valvolene #3. he mixed the two sides together and then got a putty knife and placed it over the seam. This stuff is unreal. So far in 24 hrs no leak. I think it is going to work. Everyone pretty much said we were going to have to buy a new filter. I will let you know later in the month how it goes.

My Hayward Sand Filter Tank has sprung a leak on the side of the tank not near where it looks like the tank might have been molded together. What can I use to patch the tank that will hold and not leak?

They are fiberglass ... fiberglass repair kit should do it ...

Im not so sure I would fix it ... if it is broken ... there are probably problems you cannot see ... might be cheaper to replace the tank when you consider what might happen if it breaks while you are not around.

I have a leak in my above ground sand filter, model 140. the leak is around the drain. How can I fix it? It is a Hayward, high rate sand filter, GM series, model 140ab. Thank you

Usually in th bottom of the filter you have two parts. The first is a piece with a screen that threads into the plastic housing. The second is a Cap with a rubber washer inside. Make sure the rubber washer is there. Do not overtighten the drain into the houseing

My hayward sand filter is leaking out of the side seam.Can I seal it? Thank you for any help.

Most likely not This is tough plastic, and you have have water pressure in tank. Did the filter get overpressured? Did it freeze in the winter. Try Craig's list for a good used filter.

I have a Hayward sand filter and the top is cracked and leaks. When I patch it, it just cracks somewhere else

those tanks are designed to hold alot of pressure. If it is cracked, it's already unsafe. When the pump turns on, the tanks usually flex a little bit, depending on your system. The flexing usually makes the patch come undone. It's best, and safer, to replace the filter tank.

I have a 166T hayward filter. The gray filter

I don't think you can buy just the filter tank. Most places only sell the filter tank w/skirt, drain & lateral assembly as a single unit. If the crack is more than an inch or two long I would not risk repairing it as there can be upwards of 30psi when the filter is dirty (safety issue). You can try some epoxy on it if its a very small leak but the success rate for that kind of repair is not very good.

Sand in my waste water

O-rings or gasket are replaced to stop leaks, so that wouldn't have helped you.

It could be one of two things; either the white PCV-like pipe in the filter tank is cracked OR some of the laterals at the very bottom of the tank, under the sand, has melted. A whole new underdrain assembly is usually $70.

Ive got an older hayward vari flow that leaks out of the flange that bolts the valve to the tank, Ive been trying to get a new oring but all the pool people been getting me the wrong one, there all too...

Most hayward sand filters use a GMX600F or GMX600F-H o-ring.
If it is an older tank it might use the GMX400F which is smaller, and rare to come across. Most 400 Valves are not marked vari-flo.

Hope it helps.

I have a baquapure sand filter please help

if leak is around the top 7-way valve it is probably the rubber o-ring underneath that needs replacing. if the tank itself has a crack or hole you could try something like j/b weld to patch the hole.
