Hayward vari flo valve

I have very little pressure from my filter from 0-5 when it should be 10-15. I think it is the spider gasket on the hayward vari-flo valve. I bought a new gasket but can't get the old one out. Is this gasket glued in? If so how do I remove it and what do I use to glue the new one down????? Thanks.

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.

I had a problem in not being able to easily move the handle to various positions. I took off the cover/handle assembly and found sand and some very small rocks. Also lubricated the handle several times while pushing it up and down. Try to get some lubricant down into the bearing.

Works like new!!

It will not be glued, it is just stuck in there good. You will need to scrape, pull, twist or otherwise convince it to come out as best you can and then clean the area well before installing the new one.

Hayward vari flo valve on filter also comeing out waste at same time


Yes, it is the "spider" gasket inside the valve that has gone bad. It needs to be changed out. They are not expensive. Go to YouTube and enter "change spider gasket" there are several videos. Good luck with it!

Noisy Hayward Vari-Flo Valve Model 710xr50


I HAVE TO ADD MY TWO CENT! THANK YOU TO THIS WEBPAGE- I had air and gurgling coming from my Hayward Variflo - i sealed all the leak and had crystal clear sight glass on my pump, but still gurgled- i never in a million years suspected too much OUT flow- and it is the easiest thing to test- just cover one of the outputs, to restrict the flow back to the pool, and listen- my noise died right down.

I have a 20,000 gal in ground pool w/ Hayward 36 sq ft de upright filter, Hayward Vari-Flo valve. Actual suction at the skimmer has gotten very weak, (filters and traps clean) It does better in...


You say that you can see a large flow through the pump cover but that water must be coming from the pool somehow. It must be coming through the main drain. If you turn the main drain off then the flow from the skimmer should increase considerably. If it doesn't the issue could be caused by a nearly plugged line between the skimmer basket and the pump. I have had similar symptoms and I started by using a drain jet device on a hose to force water backwards from the pump to the skimmer with the main drain valve turned off. I couldn't clear the plug so I had to dig the line up and found a bad area of the piping where it made a reduced pipe size 90 degree turn. Sycamore bark, leaves and twigs were stuck at that pinch point.

I hope this helps.

Installing vari flo top mount valve on hayward filter. Should the the two C clamps come together tightly when install is complete or should there be a gap on the ends? Example (-) vs ()


There is a gap at the ends; about 3/16 to 1/4" give or take. Just hand tighten them and if the valve leaks a little tighten them a little more at a time to avoid splitting the clamps by overtightening.

Problem with vari-flo multipoer 1.5 and Hayward DE fiilter


You need a rebuild kit for the valve and possible a sand change. Sand should be changed ever 3 - 5 years or so depending on overall pool conditions.

The gasket inside the valve is out of place and therefore allowing water to leak out the waste port. Use a gokit to replace all the gasket/orings and you should stop the leak.

If the flow is still bad, inspect the sand and change it if necessary.

Control Valve handle wont stay in position


The valve should be about $100. We sell it for 90 something. You can rebuild them with gaskets and the spring. There should be a model number on yours, care to post it? Something like SP711, SP714, etc.
