Mr
Pump is great. Had to swap tubing, but good. Added a fresh water wash out. Just have to make sure I have it sealed when in real use to keep pressure up. Great relacement for the Jabsco. We'll worth it.
David Nelson David Nelson
Great for watering my garden
I attach it to a 1000 gallon rain water tank and pump water 40 feet uphill. The pressure of the water at that point is perfect for watering my gardens. I can hear it cycling on and off as it develops pressure and then holds it. I'm very happy with it.

Little Pump Big Results!
I used this pump to run water 80’ thru a garden hose from my rain water catchment tank to water newly planted grass. It is very reliable and powerful! It had a four foot head on the pump and gave me 48 psi at the end of the hose. I did have an issue with it not shutting off a few times after the nozzle was closed and there was no flow, but that could be due to the long run of the hose. I highly recommend this pump, it won’t let you down.

James M Smith James M Smith
Works great
I use this pump on a rain barrel and it works great! I run it through a garden hose and use a nozzle to select different spray patterns and all of them work flawlessly. Would definitely recommend to friends and family.
