G Ganen 12V DC Fresh Water Pump with 2 Hose Clamps 12 Volt Diaphragm Pump Self Priming Sprayer Pump with Pressure Switch 4.5 L/Min 1.2 GPM 110 PSI Adjustable for RV Camper Marine Boat Lawn

Very powerful for the amount of power it uses, almost too powerful for my camper sink.

This seems to work well in my cargo trailer conversion. It pumps the water from my water container to my sink.It works well so far.Its very small but powerful. Overall happy with it for now,I will update at a later time.I'll add it is noisy but they all are.Good value.

Good little pump for my 15 gallon sprayer.

Works awesome & price was great

This is the second one of these we have gotten.....wait, you say 5 star for the second one? Well let me explain, lol. Got one 3 summers ago, it ran every 30 min on a timer for about 600 ft of black hosing. This pumps about 120 degree water (avg temp) into our 27’ pool and it totally works!!!! It’s super loud, but my fault-we have this in an upside down & attached to the underside of the deck, in a container to shield rain/weather. Works like a charm! Live in a very cold climate in winter and we don’t touch it! So this 20$ item runs like silk for 3 years in the conditions we leave it-I am personally impressed! I honestly think the other one works “ok”, but for the inexpensive cost, worth throwing away the old to ensure we get an 85 degree pool :)Also, great way to keep a pump out of a pool so there is no power cord hanging in a pool as I have seen other people do!

I got this pump for use in an RV and the price seemed reasonable. I didn't need much flow and figured that 1.2 gpm would be sufficient. I didn't receive the hose clamps so had to purchase separately which makes the overall price a bit higher. It's not quiet but since I'm using it for a sink, it is only on for a short time and not continuously. However, I have realized that this is a piece of junk. The pressure sensing switch is either faulty or the pump just isn't designed well since it stutters. Turn on the tap and the pump operates. Turn the tap off and the pump stops, then starts for a fraction of a second, then stops, then starts again. so it's buzz...buzz...buzz...buzz. The connectors for the hose are so minimal that it's impossible to get a decent purchase with the hose clamps resulting in constant leaks. Worst. Purchase. Ever

The first time I used it I put a tube in a jug of water on the inlet side and started it. It primed and pumped up to the pressure it switches off at. After letting some water out the pressurized side it turned back on and wouldn't pump anything. This all in under a minute. I then tried placing my finger over the suction side to see if it was pulling any water. There is no suction. I turned it off for a few minutes and tried again. It started running and in about 5 secs starting pumping again, got up to 15psi, and wouldn't go higher (still running, not tripping the pressure switch). I tried again another day, and again had mixed results. I found once it stops sucking I could shake it and sometimes get it to work for 20 seconds.I now have it installed at the bottom of a tank where there are no issues with priming and it has a small pressure feeding water to it. So far in that situation it is working well.It would appear that it works fine if you have a good air free source supplying it, but has basically no suction to prime itself. That is a bit surprising as I believe it is a positive displacement pump.

Ok, just put around 15v on this pump, added 2 hoses and it started to suck water from a bucket and then returned to it with a low volume but lot of pressure.First of all, there one small arrow indicating the exit hose, not easy to see.Second, took a few minutes to find out how to adjust the pressure, just turn the screw to the left to reduce the pressure and right to increase it. In my case i just need no more than 30psi amd this pump meet my requirement but there is not documentation that explains about the pressure adjustment.As i need it to build a portable shower, the volume of water and adjustable pressure plus some range of working voltage 9-14v, makes this pump a perfect fit to my project.Will update as project progress as realibility is the remaining question.
