VerRich 12V Water Pumps, 1/2" Diaphragm Pump 20MM Connector Self Priming High Pressure Pump for Motorhome,Caravan,Boat Garden

Our dishwasher discharge water pump stopped working and I needed to remove the water from the dishwasher before I could pull out the dishwasher from under the counter and lay it on its side to check out the problem.This pump made quick work of pumping out the water from the dishwasher to a bucket. You do need a 3/8” ID plastic hose for the input and outlet side of the pump. Two hose clamps are provided. You also need a 12V power source.It is a great bargain for under $20, as it is a positive displacement diaphragm pump with a 12V motor, and sure beats a drill pump which doesn’t even come with a motor.After disassembling the discharge pump, I was able to determine that there was a small broken piece of a cereal bowl that was stuck inside the pump. After removing it and reassembling the dishwasher it is running like new. I saved spending over $1,000 for a new Frigidaire Professional dishwasher.The pump was a life saver and I will keep it for other pumping jobs.

I replaced a failed pump with this unit on an Ironton ATV 8 gallon sprayer. This is a great pump so far. I used it for 8 hours. I did not realize that the flow went in the opposite direction as the original pump, but this was not a big deal to re-plumb it with some extra tubing. I didn't bother to check the pressure, and the pump blew up the cheapo tubing that came with the sprayer. I was surprised that this pump have that much pressure! I adjusted the pressure down and installed a new sprayer hose and it worked like a charm! For the price, you can't beat this pump.

Lo compré porque ofrece alta presión pero no conozco la presión ni como ajustarla porque no hay instructivo. Tendría que comprar un medidor de presión, y son muy costosos, más que la bomba.

Purchase this to pump water from a 20 gallon container 6 to 10 ft. to cool condensing columns experiments within organic chemistry. With the right fitting it can also be used as a vacuum pump so dual purpose but I don't suggest it be used for both at the same time. This pump has the power but one can easily end up running unwanted chemicals through the pump that may damage it. But at this price why not buy two! My second one is coming up soon.

The pump quit after three uses… not happy, and the company does not respond!

Needed a replacement for my sprayer pump and this one fit perfectly. Sprayer up and running again. Easy to install, quiet and reliable.

Look for the arrow, it may be backwards of the oem pump
