## Description

Review: Good product at a good price. Very quiet while running
Review: Hi. I ordered this product 8 months ago. I live in my RV full time and have only needed to use it 5x before. Today I went to pump my onboard septic into a stationary tank and the pump just won't work. I paid $99 for it and haven't ever had an issue before. I'm outside the desertcart replacement window, however I'd like to see if the manufacturer would offer a replacement. Thank you. I love this product!

*by E***N on 11 July 2025*

Absolutely fantastic pump! I installed the 42-Series in my RV and it’s been flawless. The water pressure is strong and consistent—perfect for showers and washing dishes. It’s super quiet, easy to install, and the on-demand pressure switch works like a charm. I love that it’s self-priming and can run dry without damage. Great value for the price. Highly recommend for anyone upgrading their water system!
