Whenever I hook up the vacuum, the pump loses prime and suction is extremely low. I've hooked up the vacuum hose to a skimmer basket and plugged off the other skimmer to maximize suction. I've ensured the hose is completely filled with water when hooked in to the skimmer basket. The pump will stay fully primed and at full power until I plug in the vacuum hose--I get a few seconds of good suction, but then the pump loses prime and suction.
Any ideas what could be wrong? The pump pulls strong through the skimmer until I put the hose in place.
There appears to be a very tiny amount of air getting in to the system, nothing significant, but I see a small amount of bubbles coming through one of the returns when the pump is running. I've had a leak on a poor pvc job after a fence installation hit some underground plumbing, and this is a significantly smaller amount of bubbles than occurred during that time, so its hard for me to think that is the culprit, but I could be wrong.
