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

I used this pump to draw water from a pond to water a 40 foot pollinator garden. I used it in conjunction with a 12 volt sealed gel cell battery made by the same company. It is drawing water through 14 feet of pvc pipe and water hose that I did fill with water in advance to pre-prime the intake. I also installed a check valve at the far end of the intake pipe to keep the water from draining each time the pump is shut off. I can only say that I am extremely pleased with how well the pump works. I installed a waterproof rocker switch between the battery and pump and installed it all in the ground in a standard valve box. The battery is being charged by a solar panel so the whole system is very simple to use. As soon as the switch is flipped the pump is filling a shrink garden hose to 70 psi in seconds. It works so well that if you shut off the hose nozzle for a couple of seconds the pump shuts off because it is at maximum pressure. As soon as you reopen the nozzle the pump starts right up. You can't go wrong with this pump.

Used for spraying of my fruit trees. Make sure that you flush the pump with water after every use to for increased lifespan.

I plan to use this as a softwash pump to do roofs and clean other exterior surfaces. I got it all hooked up with about 45 feet of 1/2” hose. It ran great for the maybe 10 minutes of testing and easily shot over the top peak of my one story house. As long as this can last for a few jobs it’ll be worth it for the price. Everything fit and no leaks easy to hook up So I’ve used the first pump on multiple house washes plus prior to that used it for watering the garden last year. The first pump is still working great so I ordered a second and plan on building a siamese system using 2 of the 5.5gpm pumps hoping to get close to 11 gpm. I used 1/2” hose for one I plan to run 1/2 into 3/4 plumbing and hose on the Siamese setup. Haven’t tested the new pump yet hopefully I’ll get the same results.

These are very strong and durable. Going strong after 2 years still. This pump can handle the needs of my food truck!

Easy install, takes a bit more power than my old pump lights flicker when running low pressure, i don't think thats a product issue just a power output issue on my 30 amp camper. Great pressure will see how long it lasts.

Really good pump had it for a few months now. Recomended I used this pump for rain water my plants.

Well constructed. Motor seems heavy duty. Not cheap RV crap.

Having issues with pumps don’t turn of on the pressure switch what can I do? Other than that pumps are great. And price is great need to purchase more before price goes up on the 12 volt pumps self priming 70 psi Need to buy some more pumps vevor sells good pumps and price is great and they never run out of mechandise

Used this pump for rain catchment and it has worked great for several years. Had an issue with the diaphragm switch and vevor promptly sent me the part free of charge.

The pump is actually really great. It not only works just like you would expect it to, but is very easy to mount. I bought this for a custom temporary water setup on a house that I am building. Works great and was very easy to mount with a simple power setup. No problems as of yet, so as long as it keeps working I am very satisfied.
