I haven't used the spa this summer and I noticed the water level was down before I drained and cleaned it. Upon refilling it leaks down from full to the middle of the highest jet. This is the highest jet in the tub, it's higher than the skimmer too. The water leaks into the blower box until it drops below that jet. It has ruined the blower motor also. Anyone ever have this problem? Also, does anyone have a piping drawing for a 1989 Supra Lounger? Thanks ahead of time. Tim C

Just want to let everyone know what fixed my problem. The tech at my closest Sundance dealer told me my Hartford loop was full of water. I drained the tub and blew out the loop, but also installed a check valve, and this seems to have corrected the problem. The tub was refilled and this seems to have corrected the problem. Tim C
