Customer Reviews for VEVOR Water Diaphragm Pump, 13.25 liters, 55 PSI Rated Pressure (40-80 PSI Adjustable), 12.7mm MNPT Self Priming Sprayer Pump with Pressure Switch for RV Camper Marine Boat Lawn, FCC Certified

I bought this 5 months ago for a booster pump for my RV. It is in a heated compartment, the RV park has really low water pressure. There is nothing externally that could have ruined this pump. It busted after only 5 months and sprayed water everywhere. I will be lucky if there is no mold or mildew from this type of leak while I was out in town for a few hours. There should never be a massive failure like this form normal use. Photo attached showing it isn't leaking from any fitting, connection, or hose. It is leaking from the back, top of the pump.

I have no idea if this pump works well or not because I have yet to get it set up due to the wire that connects to the power source being so short. This might not be an issue for someone who knows a lot about wiring, but I have no idea what gauge of wire I need to purchase in order to connect this to a battery. I sent a message to Vevor asking for guidance but got no response so this pump is absolutely useless to me. I will have to order another pump from somewhere else that had more than a few inches of wire..

Didn’t work out if the box. Verified polarity before hookup but it just hums when powered and pops fuse

Very disappointed. The first one i bought worked well for a while but then it became obvious that the pressure switch was not turning it off. Instead the motor was stalling and heating. Eventually the motor burnt out. So I bought this one (same as the last one). Again drawing current when not in use because the motor stalled before the pressure switch opened. If you don't like changing your pump frequently, don't buy this one. Warranty procedure is ridiculous. How am I supposed to submit a video of a stalled, overheating pump?
