"POOL MOTOR SAVER" (not yet protected)
Ten million swimming pools in USA. Almost all have freeze protection. I invented an overheating pump motor detector and cutoff with reset.
We will make swimming pool pump motor overheating detectors that interrupt the power until whatever caused the pump to lose prime is solved and the homeowner resets the unit to protect the equipment. When pool pumps lose prime, the motor, controlled by computer or timer, keeps running. The heat then causes pump baskets to warp, impeller seals to burn up, bearings to burn and then the motor burns, all at great expense. All pool owners need this!
