SEAFLO 33 Series Water 110V AC Pressure Pump - 115V AC, 3.3 GPM, 45 PSI, Self Priming, Smart Pressure Switch, for RV/Caravan/Marine/Industrial Use-NSF, CE & Rohs Certified, UL Listed, 4-Year Warranty

Recived on time, all parts present. Works great for my hunting camper with shower, sink, hot water tank, and toilet.

Product works great hooked it up to a three base sink and diverted hose to a one single sink and pumps very well

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.

I live in an off grid, solar cabin. I bought this, along with a 4 gallon pressure tank, to feed water to my house from a reservoir, which I fill with a submersible well pump. It works great now, after some tweaking, but it wasn't the pump's fault.The pump will work without a pressure tank, but it cycles everytime the pump comes on. I bought the tank to eliminate this problem, but I set it up like a typical well system: 2 psi below cut on pressure. It actually should be the same as the cut on pressure, which is usually 30 psi for this pump, but it is adjustable, and I installed a pressure gauge to measure the line pressure.The other issue I had was priming. My pump is about two feet above the top of the reservoir, with the end of the suction hose about five feet beneath the pump. As soon as the pump would shut off, it would start to lose prime, even after I checked and tightened all the connections. The pump really had to work a lot harder. I installed a check valve near the end of the suction line, almost like a foot valve, and it works great. Haven't had a problem since. If the pump was under the reservoir I don't think this would be an issue.It only runs one faucet at a time, but that's all we need. If that was an issue, Surflo makes more powerful, five chamber pumps.I definitely recommend it.

This pump works great I have only used it for a week but does the job of increasing pressure on a long line. It has a little bit of a noise but it’s a good cheap pump.

UPDATE April 2023: screw this thing! It’s in the garbage now. Went out of town for a weekend and came home to a flooded kitchen. The pump kept cycling on and off until enough pressure built it sprung a leak around a hose clamped vinyl tube fitting going into my hot water heater. Eventually it failed completely and the pump emptied 350 GALLONS of water into my kitchen 🤬 there were absolutely no leaks in the entire system, I checked, triple checked, quadruple checked, checked a million 🤬 times; NO LEAKS EVER. Absolutely no reason the pump should’ve been cycling without a faucet open. CHEAP GARBAGE. Haven’t even had it for a year! DO NOT BUY unless you can put it somewhere it’s not gonna flood your entire kitchen!After a couple of months of using this pump it started cycling on and off every few minutes. Checked for leaks and there wasn’t one anywhere in the plumbing system. Used it this way for a month or so, figuring it must just be how it functions. This morning I woke up and turned on the water, turned it off and it wouldn’t stop cycling. Pulled it apart and discovered TONS of plastic white shavings throughout the pump. Inspected each piece and didn’t discover anywhere in the mechanics that could’ve been grinding these white shavings inside the pump. Only thing I can think of is that these white shavings have been there from the beginning from the manufacturing process. One of these shavings had lodged itself inside the impeller and prevented the pump from working. Pulled all of the white shavings out, reassembled it and now it works alright. I will say that they did make the pump fairly easy to pull apart and service though. Frustrating that a factory defect caused the pump to fail. They include a sediment filter to keep stuff from getting into the pump so they are clearly aware that any fine grained material entering the pump can cause issues so it’s frustrating that they would allow a defect such as this to occur. Other than this issue it has been a fine pump. Only other complaint I have is that it is very loud and obnoxious while operating, but from my research that’s how the majority of these on demand pumps are, so I guess I can’t complain. Beats not having running water at my off grid cabin, I guess.

nice pump,donated to police k9 unit for use with 600 gallon tank I donated to them
