Review: Great replacement pump - Very nice pump. Installation is simple, but it would be nice if there was a better assortment of connectors provided. Like many have commented, some installations will require an additional connector. The slide lock connectors that attach directly to the pump are nice. Just insert the fitting and push in the lock. The pump is quieter than my old one but you have to be careful not to over tighten it. If you do, you'll crush the rubber mount and the pump will be solid to the mounting surface and it will be very noisy. I had to loosen the mounting screws. With the switch system on this pump you can draw a small quantity of water without the pump starting. The pump holds pressure well. With my old pump it would run for a couple of seconds every hour since it would lose pressure. With this pump I can turn it off and wait a couple of days and when I turn it on, it doesn't have to run to build pressure because it's held pressure without bleeding down.
Review: Don’t count on any warranty support - I’ve purchased 2 of these in the last two years. The first one failed right after the desertcart return window closed. After calling the support line and a few troubleshooting steps it was determined the “motherboard” was faulty. I was then informed they were out of stock and I was assured I’d be out on a list to receive a replacement as soon as they were available. After 6 months and several follow-up attempts I saw they were listed again on desertcart. I contacted seaflo again and was informed I needed to contact another supplier then crickets. Finally after many attempts to Contact someone went. Ahead and purchased another one directly from Seaflo and was assured there was a 4 year warranty. It didn’t work as well as the previous one before it almost burnt my RV to the ground. Now less than 2 years later it has completely stoped working. I’ve filled out several forms for warranty and found they have put so many road blocks in the process, and no way to actually talk to a human I’ve given up out of frustration. The pump was fantastic but don’t last. Good in theory but crappy in execution. I would certainly NOT recommend buying anything from them for any reason.

### ⭐⭐⭐⭐⭐ Great for Off Grid Applications.
*by D***S on October 17, 2025*

I bought this for an Off Grid tiny home for my elderly mother. I ended up using it on my house (Off Grid Too) My wife is a dog groomer, and when bathing a dog, the water flow was low enough that it would destroy the pressure switch on other pumps designed for RV’s in a very short time. This pump has NO surging. It is connected to a 1,600 gallon water tank feeding my whole house. I live at 6,500 feet where it freezes in the winter. The motor does get hot. So caution when wrapping it with insulation. Can’t fault the company tho, I am a few feet above the Sea…..
