Aloha everyone,
I have an apparent leak on the suction side of my system. Trying to diagnose where, but have not been able to pinpoint it yet.
The symptoms are, when the pump turns on about 9am, there are air bubbles (large ones, that you can hear bubbling up from 20 feet away), coming from the returns. The bubbling lasts for about 20-30 seconds, and then, stops.
When the pump is running, I can open the air bleed valve on the filter and bleed out a small amount of air. The pressure valve on the filter reads 0 while the pump is running (it was reading in the 5-7 lb range before)
I have checked the water level at the skimmer - it is at the proper level, and no air is entering through there.
I have checked the vacuum hose, and it is not cracked or leaking.
I have replaced the pump strainer lid o-ring, and it is new, lightly lubed with o-ring lube, and does not appear to be the source. The pump strainer lid also does not appear to be cracked or damaged.
All of the above ground suction side PVC pipes and connections appear solid and I don't hear anything that sounds like air entering the system.
What are your thoughts or suggestions?
many thanks
Bob
