Have had a Sunseeker 3 years and never had this problem until this spring. The water has a slight sulfur odor. I have drained the whole system and refilled, but problem still present. I fill from our well (filtered) and don't have this problem in our house.

Also the frig is freezing food. I have set the temp control to the lowest setting to no avail. This just started this spring also!

Any help/information will be greatly appreciated!
