I recently came back from a two week vacation and found my pool level 1.5 feet below normal with water greener than Shrek. I usually turn off my skimmers before leaving but this time I forgot.

The pump ran dry. The booster pump for my polaris went bye bye but the main pump seems ok. I don't know how it survived. It was set for 5 hours a day. Must have quickly got too hot and shut itself off.

I set my sprinkler system to dump water in the pool every other night expecting a lot of evaporation in the Texas heat but I guess it wasn't enough.

In my opinion, the most important thing to do (if you leave the pumps set to turn on) is to turn off your skimmers.
