Features to know about

Automatic Pressurized Faucet Water

When you turn on the faucet, you expect steady water, not sputtering or uneven pressure. This 24V automatic pressure pump restores smooth, pressurized flow at the sink or shower with integrated start-stop control. Rated up to 3 bar (45 psi), it maintains consistent freshwater delivery across multiple fixtures without manual cycling.

Self-Priming From Below Tank

Mounting a pump above the tank can make priming more demanding, especially when vertical lift is involved. This unit self-primes up to 3 m (10 ft), allowing flexible placement relative to tank height. Reliable lift performance supports consistent water delivery after system cycling or maintenance.

Runs Dry Without Damage

Low tank levels or intermittent supply can damage standard pumps. This model is designed to run dry without damage, reducing failure risk during temporary water interruptions. It maintains operation when supply conditions fluctuate.

IP67 Sealed Motor Housing

Damp marine or RV compartments demand protected electronics. The IP67 sealed motor housing supports installation in moisture-prone areas. Sealed construction reinforces durability in enclosed freshwater system spaces.

Flexible Plumbing Connections

Retrofit installations often require connection versatility. This pump supports quick connect 15mm female ports plus (2) 1/2" threaded and (2) 1/2" barbed fittings included. It integrates into established marine plumbing layouts without redesign.

Video Transcript for Review of Whale Boat Water Pump - Freshwater Pumps - AT36GR

Hi everyone, Steven here with etrailer.com. Let's take a look at our Whale Watermaster automatic pressure fresh water pump, runs on 24 volts. Folks, this delivers smooth, consistent flow and runs dry without having to worry about damage. So if you do run it dry with nothing going through it, you're not gonna damage it. You've got some rubber isolators here for whenever you're mounting it, you can spin them out, mount it however you need it. So it's pretty versatile as far as that goes.

And of course you have your electronic wiring hookups. You have a nice inline filter here it looks like. And then two each of these different connectors that are simply just push connections on the pump itself. It's a self-priming up to 3 meters or 10 foot. It delivers smooth, consistent flow.

And as I already showed you, those mounting feet rotate so it makes it easy to install. This has been IP67 sealed and in a protected motor housing with an integrated pressure switch inside. Overall, it's about eight and a quarter inches long and roughly a little over six inches wide and about five inches tall. So again, folks, the voltage is 24 volts. The host connection are quick connect 15 millimeter female connections, and two inch long by half inch threaded connections.

And that's gonna wrap it up for our quick look together. I'm Steven, thanks for watching.
