Backwashed, hose primed with water from jets, extra skimmer plugged. We've been doing it for years, but this year we are having problems. Whenever we hook the hose up we get minimal suction. at first the pump was losing its prime, after some troubleshooting we can get minimal suction.
The pump works fine on recirculation, and filter without the hose. we notice air bubbles when the hose is connected, but the hose is new without leaks and we tried two separate hoses to be sure. (my initial thought was the hose). Or the pump.. It seems as if the pump is having trouble handling the extra load of the vacuum hose. Any ideas?
