For years I've had a suction side leak at the check valve. Basically the screws don't grip and hold down the cover anymore. I've band-aided with the situation with goop , and using toothpicks to allow the screws to take hold, but it leaks like crazy, just get's worse and at times wont prime. I was thinking it might be time to replace it , but as you will see from my photos that might be harder than it could be as there is no clearance to make a new connection to the filter inlet. Was hoping to get some advice on how to proceed from someone with more experience than I on how best to handle this, I'm handy and have no problem working with PVC Many thanks !!
