Question about Hayward SAND FILTER, PRO SERIES

1 Answer

Is there another solution to fixing the spider gasket on my heyward filter other that replacing the whole valve assembly? Are there any home remedies out there.

Pool supply house says that I have to replace the whole valve assembly on my heyward filter in order to replace the spider gasket. I'd llike to know if someone has come up with a alternate solution to fixing this problem. Any help would be greatly appreciated. Thanks.

I would try to change the gasket first ... be sure you look at the gasket BEFORE you remove it so you can put the new one in properly. Typically, it is the gasket that goes and not the valve. Remember, you can only turn the handle in a clock wise direction - never backward. or is that counter clock wise ... :-)

SOURCE: pool filter is not filtering the dirt out of pool.

will replacing the sand make any difference?
Only if you have very dirty sand. -But seeing as you have backwashed it - I would say it will help but not fix prob.

Have you got all pipes in right holes?
Did you put head stock on right way?

SOURCE: after replacing gasket on filter vacumed pool

I would suspect that there is a fault in the filter, a bnreak in the filter elements, a bad alignment, a colapsed support. something that is letting the dirt get back in to the pool

SOURCE: while vacuuming my pool, valve

Hi, my name is John I will do my best to assist you.

Normally the valve head on these sand filters has a selection for "Pump To Waste" this is the setting that should be used when vacuuming. The pump water will flow out the backwash hose/line so that the contaminated water does not flow through the filter and back into the pool.

A lot of water is pumped out using this process, so it's a good idea to have a water hose refilling the pool while you work. Unless you can work quickly you may not be able to completely clean the entire pool at one time. Pay attention to the water level, and when it drops to the low level mark on the skimmer stop and wat for it to refill.

The "Filter" selection is typically intended for normal pump circulation only.

If you have more specific questions please post comments to this thread and I will endeavor to monitor new activity and respond as soon as possible. I recommend that you "bookmark", or "add to favorites" this page for your convenience.

SOURCE: I have a hayward SP714

Sand filters have a screen at the bottom. This screen keeps the sand from getting out because it has slits or holes that are smaller than the size of the sand grain. The slits are large enough for the water to pass. If the material breaks there are areas that are large enough to allow the sand to pass and this won't stop until you replace the strainer elements.
In order to do this, you must remove the sand, remove and inspect the strainer and replace the sand.
Bring your model to a local pool supplier, confirm what I am saying, make sure they have the necessary parts and go from there.

SOURCE: While vacuuming my swimming pool

Try changing the setting on your pool filters control valve to waste. This will bypass the filter and vacuum directly to waste. If this works, it could be a problem with the filter's "filter" setting and you may need to service or replace your control valve.

How do I replace the spider gasket

What filter do you have?

Some of the newer filter valves, do not have a replaceable spider gasket, it is part of the rotor base plate, like on a Hayward SP714 T1 Style valve.

See Pic:

25522633-w440f4xqb2ju5vbxyy5bo3yg-1-0.jpg This type is on the rotor assembly vs. the style that has the gasket as part of the valve body, and that is removable and replaceable, see pic:

Hayward pool filter Model SP711 alignment on filter, ports, spider gasket replacement

Remove the 6 screws from around the valve assembly. Pay close attention to the current orientation of the valve assembly before removing. Lift the value assembly straight out and the spider gasket is on the bottom. This could be twisted a little which would also cause your back flush port to leak when positioned in the filter position. If twisted, just position back in alignment with the valve holes on the bottom of the valve assembly. If the gasket is worn or torn then just replace and place the valve assembly back in the valve housing and replace all 6 screws. If you still have problems with water not functioning based on the way you have the handle turned then it might be time to replace the entire valve assembly.

How do I check the backwash valve?

Is it a vari-flow valve?
If so with the pump off set the valve to "filter" then you can remove the screws on the top of the valve and remove the assembly. The gasket that usually goes bad is the "spider gasket", it looks like a pie-chart. Check this gasket for any tears or bends in the rubber, if you see any replace it. Turning the valve with the pump running will cause these gaskets to go out

Waste line leaking

The wagon wheel looking spider gasket inside the has bit the dust. Depending on your valve model you may be able to just replace the spider gasket. Some manufacturers don't offer the gasket as a stand alone part and you have to replace the diverter assembly. If you post your valve model, i can send you a link to the proper part.

This gasket usually goes out because someone lifted the handle on the valve while the pump was running. Be sure the pump is always off before pressing down on the handle to change positions.

Drain leak

Your spider (diffuser) gasket is pinched or damaged. You can replace it for under $20 unless it is the SP0714 model. If it is a 714 then you have to purchase a new key assembly or a whole new valve. Usually runs about $80-$120.

I have a brand new leaking lots of water from my backwash when on my filter setting

Your multiport spider gasket is bad. Just replace it by removing the top assembly. Remove the 6 phillips screws on the valve cover and the whole assembly will come off. This is easiest done when the valve is first put on the "Winter" position

Hayward vari flo valve

If the spider gasket in the vari-flo valve is no good, you will usually notice one of two problems.

1. Water leaking out backwash port while filter is operating.
2. Valve positions are really difficult to change.

The way to check this is if you are able to move one or two of the "spokes" in the gasket freely(out of the track it sits in) once the top of the valve is removed.

If so you need to replace. The gasket is usually held in with a silicone sealant. Once you remove the old gasket. You will need to scrape any remaining rubber from the track it sits in. I've found that a brass brush from a pluming supply store or home depot along with a flat head screwdriver is usually enough to do the removal.
I always used Permatex Blue RTV sealant on all valve jobs. It can be found at any auto parts store or sometimes Walmart. Follow the instructions for curing. Once cured the gasket is good as new.
