  • Great buy, Great Performance, Low Price
Size: 3.5GPM-45PSI-12V-Standard Package
This pump works just as well as the popular brand we find in most stores in the Caribbean and is quieter. Water volume is perfect. Easy to install.

  • Only surprise was how well it worked.
Size: 3.5GPM-45PSI-12V-Standard Package
I feel most people, and for me a technician who installs such stuff, this little pump surprised it's new owner (37' sailboat) when we opened all 3 valves to full in order to drain the tank for service. It not only emptied the large tank in about 20 minutes, it did so without showing it at the taps. I was pleased for recommending it and had little issues with installing it. I will buy a few for myself as well. ... show more

  • Doesn’t last
Size: 3.5GPM-45PSI-12V-Standard Package
I purchased this in November of 2025 and used it once and winterized my camper for the season and when I just de-winterized my camper the pump no longer pushes water. It is just a trickle the pump primes but when I turn on the facet it comes out with a little pressure at first and then goes to a stream I turn off the water again and it primes and the same thing I get a little pressure when I turn it on and then nothing. Which is what it was doing before I replaced it. It worked great in November for our camping trip and now it’s already gone bad. ... show more

  • Works as well as Shurflo
Size: 3.5GPM-45PSI-12V-Standard Package
Installed in an off-grid bathroom for sink, shower and toilet. It pumps well and gives good water pressure. This pump is quieter than the Shurflo it replaced and fit perfectly. The best part is it was less than half the price of Shurflo and functions perfectly.

  • Inlet/outlet thread surprise!
Size: 3.5GPM-45PSI-12V-Standard Package
If it lives up to the propaganda I’ll be happy. I haven’t tested it yet but have learned that the inlet and outlet are not 1/2” NPT, as the manual states. 1/2” brass NPT fittings do not thread onto it. I’ll be recutting the threads with a NPT die.
