What could be causing my bubbles? Pool was finished in November, and I notice bubbles coming out of the pool return when solar or heater is running, now I have bubbles in the spa when spillway or heater is on, my PB has stop by and is telling me he sees no air leaks and it could be the 3" plumbing and I should try running the pump at a higher rpm to clear the air out.
Checking the pool this morning when cleaner was running and I have no bubbles.
So what is this telling me???
