DC HOUSE 42-Series Water Pressure Pump, 12V, 3.0GPM, 55PSI Water Diaphragm Pump Variable Flow with Filter for RV Yacht

Great lil pump, very stout, and skookum. It will self prime. It has a unique 3 impeller design. Water won't flow thru while pump is off. Great pressure while pump is on. A bit loud... but it's outside, I can't hear it while In the house. I use it in a closed loop baseboard heating application with water reaching 150deg at moments. It's a home made Boiler system where the pump draws from a open tank and pushes it thru a tankless water heater dedicated to this task, then to the baseboard convection heater, then water returns to the tank. The tank temp varies but can reach 150 deg. Pump is a high grade reinforced unknown plastic type, but handles the heat like a champ. I do not use the included filter as that is cheap plastic and would melt....uh,it did melt.

Use the booster pump help with low pressure at the RV park , work great for about a week and then started leaking from around the plastic can’t get replacement parts. Review the product here on Amazon seller got in contact with me and immediately sent out a brand new pump after sending him a couple pictures of the problem great customer service have to change a couple things but other than that great customer service

We bought this pump to try and save a little money. Pump works horribly. Water barely pumped, had lots of air in the water, and ran without building pressure. Horrible. Took it out, checked everything, dimantled pump to check for issues, none, put back in and still bad. Switched back to Shur-flo, and water is back to expectations and shuts off immediately after building pressure. Avoid for sure!

The price was good and it works very well.The only downside is that it doesn't seem to have an integral back flow preventing valve. When I hooked up a campsite water connection, water back-flowed through the pump into the water tank and overfilled it, causing water to leak into my trailer. This never happened with the old pump. Order a check valve to go with it.

I used this for drip irrigation for the garden. I used it for a year and one half and it broke. Not sure if my fault or not because I do use it to pump lake water. I called Amazon they put me in touch w/ the seller and they sent me a new one w/in one week and did not give me any trouble. I did not have to return the old, so, there were no out-of-pocket expenses. I do recommend this pump because it does work great and has a 4-year warranty and they have great customer service.

It would be nice if an adapter that can connect to a standard garden hose was included, but it's not hard to get an adapter. Otherwise it works great! I have an RO/DI filter in my garage that fills a 55g drum. I use that to make saltwater for my fish tank, top off the fresh water that evaporates from the same tank and I use it as a spot free rinse after washing my cars. Previously, I was filling 5g buckets and carrying water around. Splashing buckets of water on your car kind of sucks. Now I hook this pump to my drum, connect it to a hose, turn the pump on and it pumps water to my fish tank or even through a regular garden hose and sprayer nozzle to rinse my car. I really can't tell the difference between my city water pressure and the pressure from this thing pumping water out of my drum. The pump is pretty quite and I love that it shuts off when the pressure in the hose gets high enough. I can just close the nozzle on the hose and the pump shuts off. I've only had it for a week, so we'll see how long it lasts.

I used this water pump for my food truck and after the second one stop working less then a few months maybe 6 . I have decided to look at another manufactor. This is a big pet down in the food business and not to have water.

I used this pump on a watering system for my indoor plants. I designed the system to be automatic while I was on a trip for several weeks. After returning, the water pumped was as expected and the plants were healthy. The pump is quiet and operates on 120 V. I did not use the included flexible fittings. I used schedule 40 pvc fittings to install the pump in a fixed situation. I would suggest that if you intend on using the flexible fittings that come with the pump that you should install some anti-vibration material between the pump and mounting material to minimize any vibration and noise. I also installed a stand/expansion pipe in the system to reduce cycling.

Works great

Pump is not too noisy. Had a issue after a couple months. Seller was really easy to deal with and is shipping new pump out.

The media could not be loaded.  UPDATE 2021-11-15: After a bunch of back and forth they have sent me a replacement pump. I have yet to test it...In short: the pump head leaks and they won't replace after < 2 months. See video.I got this pump a little less than two months ago and tested it within the first few weeks for my project. Seemed to work out. I've finally got to the part of the rain-water harvesting project where the pump fits in and I found the pump kept cycling on and off every 5 minutes or so. At first It thought it was my shabby plumbing but on closer inspection, the pump head is leaking in multiple places. (See the video for one). It leaks while running and while idle, under pressure. Some quality control that is...They won't replace it because it's too late apparently and aren't offering a way to fix it apart from giving me a discount if I can fix it myself. Like I need more work to do.... <sigh>

This seems to be a well made pump. It's very quiet and efficient. Uses very little electricity. However as others have posted, it can only run for one hour before the motor becomes incredibly hot. As you can see in the photo, I created a water cooler that allows me to run the pump 8 hours straight with no problems so far.

The adjustable shut off pressure, allows me to leave it on, and then works when I turn on a hose.
