If you are wishing your Shower had Water to work, you could need this. This is a 230 Volt 1.5 Horsepower Single Phase Well Pump Controller. These keep your Well Pump Motor Happy. These are for the Better Well Pumps that have the replaceable guts in a box on a wall, instead of down hundreds of feet in a hole. Got an Old Box? Might want to swap it before the stuff stays in yur toilet! Give a call. show contact info
