Customer Reviews for VEVOR Water Diaphragm Pump, 20.8 LPM Flow, 4.8 bar Rated Pressure (2.8-6.9 bar Adjustable), 12.7 mm MNPT Self Priming Sprayer Pump with Pressure Switch for RV Camper Marine Boat Lawn, FCC Certified

Leider ist der Druck bzw Magnetschalter nach 1,5 Jahren defekt und man bekommt keine Ersatzteile

i’ve tried two of these on two different 15amp breakers… constantly trips breakers and gets very hot at the pressure switch.. dangerous.. great water pressure.. ive even tried turning it way down. still trips breakers

Der Schalter hat keine ausreichende Hysterese, sie schaltet ständig aus und an. Das heißt im sekundentakt, es rattert.

Pump motor quits after about 1 /2 hour to 45 minutes, it has happened four times. I’ve called several times and left messages about warranty no response.

Connections break easily. I have not been impressed with this product! It is impossible to get replacement parts for those that broke through VEVOR !

This website is the most pathetic software of all the websites I've ever been on the guy who made the software should get a beaten

We installed this pump, it's flow rate is 1.7 gallons per minute. NOT 3.7 GPM. Installed next to a 1000 litre IBC. worked for one month. Fine for just cold water with the tap open all the way. If open halfway or less it stutters and shakes. And with a boiler, with the tap open on full hot, it also stutters and shakes, and does not deliver even the 1.7 gallons per minute needed for the boiler's specified pressure. Two days ago it died without showing any signs of apparent struggle. The pressure switch is stuck on, it does not make a sound or vibrate. And the motor does not move. A waste of money. If you buy anything from this brand, be ready to install it straight away so you can use their guarantee.

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..

Business Bureau No replacement, no refund, no help. Don't trust their return policy as they don't seem to have any intention of keeping it. There is no phone number to call. These pumps are a complete waste of money. Complete Junk!instead of sending me a pickup ticket they wanted pictures of the pump!So you want a picture of your pump not working ?

Supposed to be set to pressure. Installed in my RV and it pulsates like crazy
