Water Diaphragm Pump, 12V DC, 5.5 GPM Flow, 70 PSI Rated Pressure (40-100 PSI Adjustable), 1/2" MNPT Self Priming Sprayer Pump with Pressure Switch for RV Camper Marine Boat Lawn, FCC Certified

UPDATE: I finally had time to install my mister system on my deck. This pump is really powerful at its highest setting. I had to run it down to its lowest setting in order to not get totally drenched on my deck! It rapidly pulsates on and off at this setting, but still pumps an amazing amount of water through the system., The pump does jump around a bit at this lowest setting due to the pulsating, but it wouldn't be hard to bolt it down to a board or some other large base. I noted originally that it seemed to run hot, but that's not the case with lots of water running through it. It hasn't shut down on me yet. Obviously, this is not the intended purpose for this pump, so everything I've said is for a system that it really wasn't designed for. I still give it a full five stars because it really is a great pump! I'm very pleased with my purchase, but if I had known how well this pump works, I probably would have looked for a pump with less pressure output to suit my system. ORIGINAL REVIEW: I bought this pump so that I could build up a water mister system for my deck. I don't have a hose bib anywhere near my deck, so I decided to try to use a pump. I also bought a mister hose system from Amazon. Because the mister system is 1/4" tubing and the jets are very small, I had to run the pump pressure up to its maximum setting to avoid the pump pulsating, but it works! I was not expecting just how much water this system uses, but if it were hooked up to a hose, it would use the same amount, you just wouldn't notice it as much. I've only had a chance so far to run about 3 quarts through it at a time and it seems to use this up in less than 5 minutes, so I'll need at least a 5 gallon bucket to make this work, and maybe more than one. This pump is fairly quiet and is built very well. The base has rubber feet on it and it doesn't seem to move at all while it's running. I'm not expecting any issues with it but it does seem to run hot while pumping. If it overheats, it's supposed to shut itself down, so I guess I'll wait and see. And it will run with no issues even if there is no water supply, just like the instructions say. It immediately pulls a vacuum on the intake line once submerged in water, so there is no priming needed. If I encounter any problems once I get the system fully installed, I'll update my review, but for now, 5 stars for sure!!

This pump is well worth the money. The on demand switch works As advertised. It will pump a steady stream of water 30 ft with a regular hose and nozzle. I have constructed a pump/tank assembly to assist in prescribed burns on farmland. Very please to have this pump connected to the IBC tank and 12 volt battery. Works as I expected. Just completed the project so I have no idea how long it will serve. To be continued……… The next day the pump was put to the test. Prescribed burn all morning, 10 acres +-. Pressure was just what I needed. See video. 200 gallons of water pumped and the deep cycle marine battery still had plenty of charge, in use off and on for 5 hours. Flawless operation and demand switch is immediate and effective. No complaints after using as above.

Good pump ,been using for pond fountain and has performed for a year now flawlessly

I’ve went through 2 of these now with spraying less than 300 gallons through them. They start to leak at the diaphragm and suck air. They stop priming and cannot be repaired. The plastic breaks around where the screws hold the diaphragm in.

it uses a classic thermal-current fuse, the one that degrades each time it trips, and they place it near the brushes, where the thermal trip should NEVER go, inside teh motor body with bolts of materials that are GUARANTEED to gall in the body, and heads that strip out when you even think of opening to replace the useless thermal trip with a more reliable/replaceable option if used at 60-70psi as you might for an RV potable water supply this may last a long time, but it says it can be turned up to 100psi, and one would expect that means it NEVER fails to keep doing that for AT LEAST 6 months with a few minutes a day, not so, I hope manufacturers stop EVER using those thermal-current fuses inside motors EVER AGAIN, they ALWAYS fail prematurely and often that causes additional damage to other parts otherwise a great pump, does the job, stays cool, quiet, and full featured, just terrible industry-standard protected motor design(better to simply have no protection at all like that)

Works great, installed on our cabin in the woods to have running water. No issues at all.

Worked perfect for the first 5 times of using it. Now, it won't pump up, no leaks anywhere, clean filter. It just simply won't build up, it keeps running until it blows a fuse

I’ve had this for about four months and installed it today. Right away, this unit feels heavier and more solidly built than any pump I’ve bought in the last decade of living off-grid—shockingly sturdy. I didn’t use the Anderson-style connector on the unit, so I modified it to fit my setup. You might be more prepared than I was. For a quick test, I hooked the water tank to one end and left the other end open. Instantly, I noticed noticeably better pressure than my previous 45 psi—of course, that’s expected, but it’s always great to see. I’ve designed my system for 160 psi; many RVs recommend only 45 psi, so do what works for you. Now the unit is fully hooked up, and it’s running hot water with ease and the washing machine without any issues. I love it.
