Hello, I am new to the forum and was hoping I could get some help with my problem. I have an IG pool, 29K gallons, cement, 2 skimmers 1 MD, Sand filter, 1hp pump. SWG.
I am losing prime when I shut the pump off. Also, I have bubbles enter the pool through the 3 jets closest to the equip. when pump is running. Here is what I have done so far. After turning off pump I closed all three jandy valves on the the MD and 2 Skimmers. Still loses prime. I can see bubbles enter the basket through the drain side. I have turned the multi valve to closed with same result. I have run water over all the connections while running with no noticable difference in the sound of the motor or change in the bubbles in the basket. I am trying to determine if the leak is in the suction side or the pressure side. When the pump is running it never completely primes as I always have some bubbles in the basket. It is running at 10 psi.
Question 1) by closing the jandy valves on the 2 skimmers and the MD and still losing prime does this indicate there is not a leak on the suction side? The valves are located about 6inch from where the pvc comes out of the ground. Provided the jandy valves are working properly.
Question 2) does bubbles coming out of the jets indicate an air leak on the return side?
Any help would be greatly appreciated, I have read through some post earlier trying to find a solution first but no luck yet.
