3WDP4-45-115V

Excellent pump! Installed it in my RV and it works flawlessly—steady water pressure at 45 PSI with no pulsing or noise issues. Self-priming feature makes setup simple, and it handles sinks, shower, and even outdoor use with ease. Solid build quality and very reliable. Great for RVs, boats, or camping setups—highly recommend!

This pump is awesome. Uses less amps than our 7.5amp pump. Same company but its 4 to 7amps depending on the use. Fit right in, came with the right fittings for about any fitting. Its quiet and does what is needed. Great price, fast delivery thanks a bunch seller

I used this pump to build a portable pump box to use with my water trailer to feed water supply to a sink and toilet in my lake bathhouse during the summer. Works great, powered by a 12 vt deep cell battery. Was just what I needed.

This 12V self-priming RV water pressure pump delivers an impressive 4.0GPM at 45PSI, ensuring a steady flow of water for all my needs.One of the standout features of this pump is its performance. The water pressure is consistent and strong, making tasks such as showering, washing dishes, and filling up tanks quick and efficient. It's reliable and delivers the water flow I need to make my RV experience more comfortable and enjoyable.In terms of installation, the WASSERMANN RV Pump was straightforward and easy to set up. I appreciated the user-friendly design that allowed me to connect it to my existing water system without any hassle. The self-priming feature worked like a charm, saving me time and effort during the setup process.While the pump itself is efficient and effective, I must mention that it is a bit noisy during operation. The sound level is noticeable, especially in quieter settings, which may be a consideration for those who prefer a quieter camping experience. However, I found that the noise was a minor trade-off for the performance and reliability that this pump offers.Overall, the WASSERMANN RV Pump is a reliable and efficient water pressure pump that has enhanced my RV adventures. Despite being a little noisy, its performance and ease of use make it a valuable addition to my camping setup. If you're in need of a sturdy and dependable water pump for your RV, the WASSERMANN RV Pump is definitely worth considering.

other pumps cycle on/off and pressure is always fast/slow, fast/slow, etc. if you're using an inline water heater, then the temperature varies with water flow. not acceptable.this pump has very steady flow. you adjust the flow at the faucet and it stays that way.not tested for longevity or corrosion resistance... yet.

Has been installed for only 9 months with maybe 4 trips with my toy hauler and the pressure sensor/relay is already bad. I could wiggle the wires on the terminals of the relay and get it to turn on intermittently. I removed the pressure switch, opened it up (had nothing to lose at this point) and I could see the rear contacts are misaligned and there is a good amount of debris in the switch from the contacts arcing. I ordered another pressure switch (hopefully better QC) to see if I can salvage the pump as my Shurflo lasted 12 years and was expecting more than a trouble-free year out of this Wassermann. In hindsight, I should have replaced it with the same reliable Shurflo I had. Only reason I didn't is because I was hoping for a quieter pump which I will say this Wassermann was and it had decent reviews. If you pull the trigger on this, keep your old pump for a back up if it still functions so your trip isn't ruined.

This was an incredibly frustrating process, of getting this pump to work (hang with me).I connected this pump into a solar controller with a battery and solar panel. Everything was set right but the pump didn’t start.After some trial and error, figured out that the pump required more than a 10A controller. So, I tried it again with a 20A controller and it started right up.I was super confused though, as no water was pulling in or leaving the pump. Long story short, I didn’t notice the red cap inside the inlet and outlet. I removed the clear plastic ones covering the whole thing, but I didn’t think there would be another.After I removed those, the pump worked beautifully. It’s actually super powerful. I pull water from my rain barrel for my garden and it was able to fire more than halfway across my obnoxiously large garden.Simply put, this is a good pump

Easy to install and works great
