No-low pressure cycling. Pump basket will fill (with water) and then, whoosh, drops down about half or more. Feeling the outlet jets I feel no pressure and then a short burst (not full pressure) that seems to correspond with what I observe at the pump basket. This cycle takes about 5 seconds and continues over and over. No bubbles coming out of the returns.
Yesterday I vacuumed the pool and sucked up a bunch of leaves. The problem occurred after vacuuming. The number of leaves in the pump basket seemed to be less than the number I vacuumed up. Can they be stuck in the suction-side plumbing somewhere? Would that cause the problem I am having? How does one clear stuff out of the plumbing?
PS I keep the pool open during the winter and run the pump anytime it looks like we will have freezing temps. Pump has been working fine recently, even running 24/7 during a recent cold spell.
