I just registered on this site. I actually registered b/c I wanted help w/a problem and hoped someone could help me! We have an above ground 24 foot round pool. We have had it for around 5 years. This year, whenever we turn off the pump, water blows out of the skimmer. It has never done this before. I am also noticing air under the clear lid of the pump when we turn it on. Any idea where this air is coming from, and if it is the reason we are getting water blown at us every time we turn off the pump? My hubby does not think the excess air is a big deal, and isn't worried about it. However, I am concerned that it may be damaging our pump. Any help would be greatly appreciated!
