closing the pool today, had a bunch of leaves in the middle of the pool, i thought Id bypass the skimmer basket, the pump basket and vac the leaves to waste,( av ground 28ft round sand filter) well it was good for a minute, then i lost sucking power, 4lbs of pressure instead of 18lbs. i took the multi port and flushed it out, turned the pump on without useing the filter still very low pressure, but water was comeing out. it all works but very very low sucking, the hoses seem to be clear, do i have to take the pump apart an look inside?? had to go buy the leaf bagger, were u hook up your hose to it and it sucks up the leaves it really works i got the pool clean but im worryed about the sucking power, as it will be like this in may if i dont figure this out. this is the most stupid thing that I did as a pool owner does any one have a idea ???????? Help
