Just a quick question about the use of a skimmer vacuum plate. I want to start using a plate when vacuuming my pool so the cartridge filter doesn't get so dirty. The only problem is the hose cuff will come above the water line while in use. Is this OK? Assuming I prime the hose and attach the non-swivel end to the plate, will the cuff still bleed air into the system? I know the swivel end of the hose will because it sucks in air if it ever comes to the surface, not sure if the non-swivel does also.
