Hi everyone
Hopefully someone can help me because I'm about to call in a dump truck and fill in my pool (not really). I think I'm taking in air. The pump starts up, makes a humming sound like it's priming and then starts working. Within 10 seconds, it loses prime and starts humming again... about 30 seconds to a minute later it starts working again and then the same thing, it loses it. I should mention that I had the same issue with a Hayward pump that I just replaced with a Pentair 2HP and replaced pretty much all the suction-side PVC and Jandy valve. I've tried switching the valve from skimmer to main drain but I still have the issue, so I don't think it's under ground (unless both the skimmer and main drain lines have a leak. Since It's not just a few bubble but the pump losing suction I assume it's a pretty big leak, in which case wouldn't I be losing a LOT of water? How would I go about figuring out if I have an underground leak?
I should also mention that besides a skimmer I have another round cover that doesn't have a skimmer basket. When the pump isn't working, that fills up. When it's working, water comes from the sides and drains down the bottom. The most anyone has been able to tell me about it is that is has to do with the main drain.
I read somewhere else that it could be caused by a clog somewhere in the line and to try to use a drainking to clear it, but this has been happening since last year and I blew out the lines. Wouldn't that push out any debris in the system?
I'm now at a complete loss as to where to go from here. Does anyone have any suggestions?
I forgot to mention that when it loses prime, the pressure goes to 0.
