Review: Decent little pump - Easy to wire up and supplies adequate water pressure to a few small fixtures. Simple and easy
Review: Works Great - Great Price as Well - Works great. Had to replace pump on used travel trailer we purchased. Trip was rough without the pump. Ordered it when I was at destination. Put it on before heading home and it worked great. It is a little more powerful than the one it replaced. Only problem would be is using more water than you wanted to by turning the tap open more than necessary. Great improvement actually a fine upgrade.

### ⭐⭐⭐⭐⭐ Just what I needed!
*by T***G on July 3, 2026*

This was a almost a direct replacement for the Pentair pump in my RV. A little different wiring and mounting, but pretty close. It is a little louder than I would like, but the pressure is amazing and is much more smooth than the old one. Highly recommended.
