I just conn my system together. I have a Hayward EC75A, a 1 1/2 HP Hayward Pump and a LAARS -Pool & Spa heater 180,000 BTU Pool Heater.
The heater hasn't worked for 5 years now. I was In a Major Car Crash and lost my leg, and o yeah......NO ONE maintained anything, that's why the heater doesn't work and why I had to change the pump and filter!

Well I had to repipe the entire system last year because I was sucking in air on the IN side of the filter. Well this year ( Monday 7/16) The pump started right up and filtering just like it should. I do have some minor leaks on the OUT side f the filter which really doesn't affect the system.

For some reason, the system runs fine for about an hour, then the pressure in the pump rises, and there is NO return flow to the pool. I have to keep Bumping it to try to get the pool clean. I went to Backwash the pool ans the valve handle snapped. I'm sure some of you have been in this spot. Well it arrives tomm and I'm hoping it fixes the problem?
Does anyone have any other Ideas of what could be Wrong? Any Help would be Greatly Appreciated!!!
Thank You
Joe
