I need to change the spider gasket in a hayward vari flo valve. The gasket won't come out. I assume it's glued. The valve is only 2 years old.How do I remove it and what adhesive do I use on the new one?

Re: Hayward vari flo valve
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.

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!
I HAVE TO ADD MY TWO CENTS! THANK YOU TO THIS WEBPAGE- I had air and gurgling coming from my Hayward Variflo - I sealed all the leaks, and had crystal clear sight glass on my pump, but it 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. THANKS GROUP
The spider gasket inside the 6-position valve is probably leaking. Take the model number of the valve to a local pool store and they can order a replacement. You will also need a special sealant to install the new gasket.
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.
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.
