I just had my pool resurfaced and they replaced my gate valves on the inlet and return lines. The person replacing the valves noticed a check valve in the return line and asked who installed that? I said I assumed the people that built the pool did. he said the equipment was above the waterline so the check valve was not needed. He removed it when re-piping the valves. Well, I have a 30 year old stainless steel, Harmsco Tropic=Flo single cartridge pool filter without a pressure relief valve or pressure guage. Now, it seems to be building up pressure after a brief tim of running and water starts leaking from around the lid. Could that check valve being removed be the cause of the pressure building in the filter? Never happened before in 30 years. Yes, I replaced the lid gasket. Any help appreciated.
Do I need a check valve in the return line?

Dean,
Show us some pics... Return lines don't have check valves, so we just may not understand the whole picture..
I also can't see how a check valve would have any effect on your filter...
Thanks,

Will post some pics of the current setup tomorrow. I too cannot think of a reason for a check valve in the return line but it was there and the filter did not leak when it was installed. Just saying
