Hello i just bought a house with a pool and unfortunately my on patient self decided to try and open the pool even though I’ve never done it before. The problem i am having is at the skimmer basket i am getting little to no suction at all but the pump is still pulling in water from what i assume is coming from the floor drain. I closed the valve to the floor drain hoping that the skimmer would suck but no i was wrong. Can anyone please help me out.
