I have a Hayward W560 in line leaf canister that I installed in between my Xtreme suction cleaner and hose rotator. When I install the canister everything is under water so that there is no air in the hose or canister but as soon as I turn on the pump I see air bubbles getting into the canister. It takes about 5 minutes for the canister to fill about 1/3 with air and that air then going out the canister into the pump and then the cycle starts again. The pool has a side suction port, so the cleaner is not connected to the skimmer. I'm wondering if this is normal or should I not use the canister since it is sending air into the pump.
I should add, that I wondered if I had some type of air leak in the pump, so I took the extreme suction cleaner out and ran the pump without it and the bubbles never formed in the canister. So it seems that the pulsating motion of the suction cleaner is causing the air bubbles.
