I am in the process of re-plastering the pool. My PB superintendent pressure tested the SPA line and saw water leaking around the aerator and thru the grout between coping and tile. At first he thought the pipe loop is cracked. After thinking thru this problem, I remember the masonry guy did not cement the new aerator pipe to the old pipe. As a result, water leaks out from that coupling when all the jets are plugged and under pressure.
How are the SPA loop and the aerator normally plumbed? My aerator cap sits at the coping surface. I assume all the jets and the aerator are tied to the same loop, right? In a correctly plumbed system, does water come out from the cap when it is open to let air in? If water does not come out from the cap, why?
The superintendent is coming back tomorrow to pressure test the line with a new plug, which can go down to the aerator line. Should I dig out the aerator and glue it properly? If the water does not ever reach that high in the coupling, I would like to save my trouble by not fixing it. Please advise.
