Medog Water Pressure Wash Down Diaphragm Pump 12V DC 1.35 GPM 116PSI 5LPM Pump Head 165foot for Caravan/Marine/RV/Boat/Agricultural Spraying Build in Pressure Switch

This little pump can push a ton of water! However I can't use it on my sailboat as planned. I failed to notice that it operates at 116 psi (my bad). So when I got it hooked up it blew the connections apart where the faucets were fitted onto the line. I only need 35 to 45 psi. As noted, you need to check the water flow direction before getting it all hooked up. It was opposite to the way its predecessor was hooked up, so I had to undo after I was all hooked up. Now I just need to replace it with a different model with lower psi.

First the good - moves a lot of water at up to 5L per minute. Now the bad this pump is EXTREMELY loud (I would say 90db). It also takes quite a bit of juice at 60W. I have a pressure guage and it measured the pressure around 103PSI, close to the rated amount. The cut-off is pretty lousy and the pump will continue to putter for a bit before it finally shuts off on a standard 4-gallon water tank. This pump is not something one would probably want in their RV unless they really don't care about noise. I was going to use it for a misting system with a 4-gallon RO tank, but it's too loud for that, even covered with towels and in a large box. I guess I'll just keep it since it's hardly worth returning given the price.

Pump does what it says. My application is a aeroponic grow tower with seven 0.012" orifice misters. I had for 2 months before it died. I was cycling at 30 seconds on 3 minutes off, 24 x 7. This is my first attempt at a tower so I am not sure how this life compares to other pumps. I can say that at 21$ it is hard to beat. If I got 6 months out of it I would say it was a deal.Pump is LOUD. 85 Db. when on in an ambient sound pressure level of 41 db.

I just finished hooking this pump up to work as a portable delivery system for spraying apple trees, and then whatever else may need it. I used high pressure 3/8 tubing and hose clamped it to the intake and outflow ports. Worked like a champ! I used a 3/8 barb by 3/4 GTH (Garden Hose Thread) adapter to connect to a decent spray wand, and had a spray reaching over 30 feet vertically. For 20 bucks it's hard to go wrong. When I open the spray wand the pump turns on, when I close the spray wand the pump shuts off.

Using for transfer pump to fill rv tank with 5 gallon bucket. The 3/8 fitting is too short to clamp hose on correctly. The threaded portion has a groove cut into it for some reason so a fitting wont screw on water tight for 116 psi. Could not git a 3/8 coupler to start on plastic threads.

works as advertised. It would be easier to work with if it had a different outlet attachment. The hoses I found that fit the attachment couldn't handle the 100psi(it is being used as a demand pump) so it will have to be modified to take a larger hose or a reinforced one.

Don't expect a stream of water that's going to be used for a fire hose or anything. For what it's made for and the price...hard to go wrong with this one. Now, if I still had my nice rv and was replacing the water pump in it, I'd look to sureflow for more volume and higher quality.

Hooked it up to test it out. Worked great for 5 minutes then pump quit. Not happy
