Solar plumbed backwards?

Yes, that was the first place I looked to do the switch, but my equipment shed is so crowded in that corner that it would be easier to dig up the pipes. The panels drain nicely and the air is purged into the pool when the valve turns on so I will probably leave it alone. I thought maybe I could get a jump start on the swim season in the spring if I could get a few more degrees out of it. Our western Oregon swim season is short enough as it is!

This is reassuring since I'm about to be installing ours next week. Good to know there's a fair margin of error- JK!
Glad the systems working out for you!
