My pump (Pentair variable speed) ran dry for a couple hours because of something mindless I did. It still works apparently, but I want to say its a bit louder than before (more whiny). What exactly should I be aware of going forward with this pump? I'll be closing up the pool in a couple weeks, there will be a good chance to work on the pump then if there is something I can replace inside to undue any damage I may have done.
Thanks
