Thanks for the extra input. This does sound like a possibility. The good news for me is that I am benefiting from their pool as they are elderly and happy that someone is using it more frequently. I feel that the least I can do is offer some help (along with dinner invites etc.) They as I stated are elderly and hardly know what a computer is. His pool guy is trying to sell him a $350 plus gas valve and I really don't think that is the problem what so ever. Just trying to keep them from getting into the "let's try this..." syndrome.

Thanks again.
