SEAFLO 33-Series Water Pressure Pump - 115V AC, 3.3 GPM, 45 PSI, Self Priming, Smart Pressure Switch, UL & CSA Certified, for RV, Caravan, Off-Grid, Marine, and Industrial Use

RV water pump in our fifth wheel went out so I purchased this to replace. Was able to plug into outlet in wetbay and have been using it since purchased in November of 2023. We full time so this pump is used daily to pump for showers, RV washer, dishes etc. Pump is still working well. Have noticed a pulsing of the pump that is about 30 seconds intervals; however, that may be due to a small leak we have elsewhere in the fifth wheel that we have been unable to locate. All in all this pump has done it's job well for the past 15 months we have been using it daily.

Works great! I have abused this pump for the past year and she is still going strong! Would buy again

I am not a plumber, but consider myself pretty handy. This is the 4th and final pump I got from Amazon as part of the camp shower build process (NOT defective, just trying different options). Here's what I learned, hopefully this will be helpful to others who are building outdoor camping showers.1. The pumps plastic male fittings don't match box store brass fittings. They likely won't leak in plastic-on-plastic installations, but if you're screwing a metal female fitting onto the pump's plastic male fittings, they won't fit and will leak, even though technically both will say 1/2". I used flexible 1/2" hose and some hose clamps to make it work and avoid brass to plastic fittings.2. This is an on-demand pump. You plug it in, and it will sense if water is being requested anywhere in your system and start pumping. Plan to build a system that's as leak-free as possible or this pump will continue to cycle periodically. I built a prototype garden hose system, which was full of leaks, and this pump kicked on for a second every 15-20 seconds because it assumed I was requesting water (even though it was just leaks). If your system is leak-free, the pump will stay off and silent until you open a valve somewhere in the system.3. I bit the bullet and bought the $70 PEX crimp tool, which greatly simplified building my shower system. You'll need the crimp tool, some metal ring clamps, and a few baggies of elbows, tees, splicers, and shut-off valves. I was able to build my system with zero leaks. If you're doing this, get white PEX 1/2" line, it can be used for hot/cold/any water, in other words, blue cold line, red hot line, and white neutral line are all identical and differ only cosmetically. Don't think you need to buy red line to run hot water, there's nothing inherently special about color lines - they are all the same, and the only reason they are colored is to tell them apart.4. The pump is not silent and will vibrate, which means you'll need to attach it to some kind of a solid substrate very firmly. Mine is outside and the noise is not a problem, but if you're doing an RV/interior build, you'll definitely hear it kick on and work, especially if it's bolted to a hollow surface, like under the stairs. Find a way to bolt it to a cinder block or an anvil to dampen the vibration.5. My system includes a shower and a sink for washing hands (same line, split via a T connector), and this pump is pretty amazing at supplying strong pressure across 10-15 yards through 1/2" PEX lines. You'll be able to take on-demand showers with serious pressure. My wife is still freaking out about the awesomeness of taking pressurized showers in the middle of nowhere. Apparently, gravity/solar showers are huge bummers with ladies who wish to wash their hair, who knew.Overall, if you also grab some flexible reinforced tubing with clamps to bypass brass-to-plastic size fitting size issue, you'll be able to build whatever you need. Strongly recommend.

My kitchen faucet was putting out about 30 PSI, sometimes less when others are using water elsewhere. I installed this pump under the sink to boost the pressure for the faucet. The unit was pulsating (shaking) a lot after installation. I adjusted the hex key knob to stop the shaking when water is running at full. When I open the faucet less than full, it still shakes. I am getting a more satisfactory water flow when the unit is running. But the pump as loud as a window AC so I put a power switch to easily turn it on only when I need it.Secondly, I had to install this for the cold water only because the instruction says the inflow should have 1/2" diameter. The kitchen faucet connection is 3/8" and that caused the unit to shake. I ended up changing the stop valve. And since I live in an apartment, I cannot install the pump further up the piping to pressure the water before it enters the heater. So, I think I will have to install another pump if I want the hot water pressurized too.Installation is easy if you have the following:1. Access to a 115v outlet.2. 1/2" inflow piping.3. Know how to buy adapters to make the connections.

I let this thing run dry for hours and it neve fails. It's the perfect pump for a small grow table drip system.
