Not sure what they are called but the 2 deep end ports that suck water back to the pump; how hard should they be sucking? I ask this because when I'm brushing the pool down it does not seem to suck in the dirt even when I sweep it right on top of it, today I jumped in and put my hands on both of them and can't feel anything, I'm wondering if they left the plugs in and it's getting some water back to pump .
any ideas to check that from above?
the reason I say this is because they had left a plug in the skimmers
