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 and tank
