De filter problem

I have a hayward de4800 and my issue is with the pressure relief valve the threads on top of the tank are damaged when i try and thread the relief valve in it just spins. I have a blank cap with no gauge or relief which threads in fine it just seems that the threads on the blank cap are thicker and longer. The threads on the relief valve are badly designed not because i have this issue and every 2 years the threads just break off the relief valve so i always have to replace it. Any tips on how i can maybe build something which may work or repair my existing threads?


Here is a diagram of the relief valve and my tank?

I would contact hayward by way of their website, they are good about taking care of issues like this one.

I have the same unit (mine's the 3600, tho) and I've never had a problem with it in the 7 years we've had it. Still the original fitting. The relief valve o-ring wore out, but no other problems. I'm puzzled why it would be such a problem.

Called Hayward and they are NO help they pretty much say try teflon tape or buy a new tank. Teflon tape is not helping. Today i went shopping to find fittings or anything the size of the blank cap but nobody carries plastic fittings in my size. I did find a relief valve made by pentair for a pentair tank and it has larger threads my question can i or should i try enlarging the existing hole and rethreading it and if so how would i go about it?

I can't believe they blew you off. You would have to use a tap the size of the threads of the new relief valve. There is one that has a washer and nut that goes on the inside used with a gasket/oring.
