HELP!! Second summer as a pool owner. Swam last night in lovely 85 degree water. Tested and added chlorine. Tonight, went out to check and lost about 6 inches of water. The intake hose to the pump was disconnected and the pump was running away on AIR. The water must have poured out until it went below the skimmer. Found that the return hose (at the pump) looked odd also. It was pulled down further on the hose, but the hose was still attached. I am convinced that I am a victim of vandalism because I find it incredible that the hose would just loosen? Perhaps it could. Two hoses? My main concern is the pump and how long it was sucking air and how FUBAR it will be now. Any advice on how to proceed? Fill it up with water and see or should I do something else first? Thanks.
