Great Pump!

I use it as a booster pump to speed up water delivery from my reverse osmosis system. Beyond that, the pump runs strong and is fairly quiet. Pressure is adjustable, but most people will find it works great right out of the box.

The water pump arrived exactly as described, and the pressure it puts out is seriously impressive, plenty of power for our needs.

Great 110V RV/Boat Pump

This is a good quality 110V water pump - much better than the one it replaced. The pump is solid and heavy, the motor is metal.

I'm impressed with how well and how quietly this pump runs. It's winter here, so I haven't been able to test it on a large scale, but I hooked it up to a battery and tested its function by circulating water in a barrel.

Functions flawlessly

Fast delivery. The pump works perfectly. It handles high pressure well. Using it as a garden pump with a battery and solar. 30 meters of hose is no problem. Full pressure. I'm surprised myself. Would buy again.
