I have the index Krystal clear pump 1500 gph hooked up to my summer waves elite pool. I had this same setup last year, no issues. Only difference I made is that I connected the 2nd plunger valve to the existing pump housing. I couldn’t figure it out last year. Changing the filter was a huge hassle so after a lot of research I figured out how to connect the 2nd plunger valve.
The pump will run but no water is going back into the pool. I have checked all the hoses, new filter. What am I not seeing? Could something be stuck inside the pump? I cleaned it out at the end of season and stored in shed. The pump sounds like it’s working but no water is flowing back into the pool. The hoses are filling with water and the plunger valves are open. I can’t figure out what I’m doing wrong!
