Bought this pump so I could back flush my tank at home. Very pleased with the results. It pumped a VERY strong stream of water through 75' of 3/4" hose across level ground to my home's sewer cleanout access. Easy to use, just hook up the water hose and the drain hose, turn the flush valve on and let it do its work. Turn the flush valve off and turn on the pump. The results were pretty nasty.
Hooked it up to a dedicated 12 volt
circuit, with a weatherproof outlet installed inside the fridge access door. I used a 20 amp, 110 volt plug and receptacle instead of the usual 12 volt
connections. Everything is clearly marked as being 12 volts in case I go brain dead . Looks and performs like a quality product but it is a bit pricey.
