Hello all.
I am trying to deal with an air leak for the second time now. I managed to seal the first a while back but this one seems to be somewhere underground in the suction side pipe.
Before going through digging up the pipe, I am considering buying a new pipe, installing it between the skimmer and the pump and verifying that it is indeed the problem.
Now that I'm about to get a new pipe, I was wondering about the proper size. I believe what I have now is a 1.5" piping (or 50 mm - I can't remember at this point which measurement is used for what...).
Since currently, the filter pressure is somewhere near 0, the return flow seems quite slow, and the pump seems to be straining, I am thinking of trying a 2" pipe on the suction side.
Is there a problem with using different sized piping on the suction and return lines?
I have noticed installations with multiple "in" valves (lines in parallel) and only a single return pipe. I even use the same configuration when manually vacuuming the pool bottom (during which the system seems to work better - pressure goes up to 6 psi, return flow is adequate, and the pump sounds better).
