I was looking at my pool equipment this evening, and noticed through the viewing window of one of my Jandy check valves that the flapper piece was loose and was being pushed against the outlet of the valve. I shut things off, pulled the cover off the valve, and this is what I removed:
One of the holes in the clear plastic lid where the pin goes was broken, and the pin and spring were nowhere to be found. The check valve was right after the filter and right before the three way valve for the solar system. My best guess is that the pin and spring flowed downstream and got caught in the heater.
I guess I need to order replacement parts. But should I be concerned about finding the pin and spring? Could they cause any problems floating around the system? Or significantly reduce flow?
Is this a common failure?
