Keep an eye on the HydroThurster pH. The O-Ring in the very front of mine decided to leak last night. Woke up the the nice tune of a half filled pump sloshing water around. By some miracle it appears the overheat protection actually worked this time allthough I didn't get a chance to check to see if the CPU was still good. Had to get to work. best news is all my planing to keep anti freeze off the white carpet in case a leak worked! Not a drop made it to the floor. Only half the fluid leaked out though.
I have had nothing but problems with this pump..... Sucks my Little Giant 170GPH seized up the other day aswell. I am down to one POS 200gph submersable....

When I get home I will tear the HydroThruster apart and see what gives....
