Does it do any damage if you have air in the pump?
I have two things going on. One is that when I vacuum it seems like I always get some air in the pump. Is this a problem?
Also, when the leak detector guys came, they said there was a very small leak in the pipe from the skimmer to the pump. They said that probably no water would leak out of this, but it would suck a little air into the system, and that it might get worse over time. How big of a problem is this?
