My raised spa drains down to the level of the jets back into the pool if I do not close the bypass valve that operates the spillway. I took that check valve apart and everything looked good. Put some o-ring grease on the flapper seal and put it back together. Still leaks. When they fail, are there visible signs? Seems like I'd be able to see something wrong but I can't. Any thoughts?
