Size: 4.0GPM-50PSI-110V-Garden Hose Adapters
I own two of these pumps to pump water from external tanks into my cabin. The first one has worked flawlessly - I've had no problems with it at all. The second one quit working after about a month. I messaged the seller and explained the problem. He helped me do a little troubleshooting, then when it was apparent that the pump was beyond repair, sent a replacement pump to me. I only had to pay a small amount for shipping. This has been a good product with great customer service!

This high-pressure water pump works incredibly well! From the moment I installed it, I noticed how powerful and efficient it is. The water pressure is strong and consistent, which makes it perfect for many uses like cleaning, watering, or general household needs. The pump feels very solid and well built. Installation was simple and it started working right away without any problems. I also appreciate how smoothly it runs without making too much noise.

Easy to set up and works like a charm for moving the water out of my rain barrels and up a sloped backyard to a fountain ~100 feet away. Nice touch that it comes with the adaptors you need, which was very appreciated.

Has the fittings ready to go I do recommend getting a little hose to go from the tank to pump but works great for my electric and gas pressure washer stops pumping as soon as there’s no flow or once you let off the trigger love it would definitely buy again

This pump failed on me after about 4 weeks of running it for 15 minutes per day. So why 4 stars? Well, I think it was my fault. It's a long story, but stick with me. I bought this pump to feed water from my rain barrels to a drip system. The drippers are supposed to have max 40 psi. Instead of getting a regulator, I decided to just reduce the pressure on the pump using the adjustment screw. The instructions for doing this are confusing and mention a bypass mechanism. However, when I adjusted it down everything seemed to be working ok. Flash forward a few weeks, and I notice a lot of vibration coming from the rain barrel and supply pipes. Water was still pumping fine, so I didn't think much of it. A week after that it stopped working. In retrospect, I think the pump was rapidly cycling on and off (i.e. multiple times per second) and the pressure switch wore out prematurely. Luckily, it's fairly easy to remove 4 screws, pry apart the housing, and replace the switch. Look for "Snap Action Micro Switch" here on Amazon, but make sure it's "normally closed" or NC and not the normally open variety. I just ordered a couple of switches, and I'm sure that will fix the issue as I verified the pump still works when I bypass the switch (be very careful if you try this, because it's 120v). I'll just throw in that otherwise this pump is great. I plugged it into a wifi-connected switched outlet, and I can control the irrigation from anywhere. I guess one other thing to know is that the pump doesn't act as a valve. My rain barrels sit above ground, and even with the pump off a small amount of water seeps through it and out to the drippers due to the small head pressure. I ended up buying a solenoid valve that I control with the same outlet.

I bought two of these because I (stupidly) ruined the threads on the first one. It is installed between a 250 gallon IBC tote and the water line into my house ( my well ran dry ). Pump turns on when you open a faucet and off when you close it. NOTE: does not play well with a well pressure tank - turns on and off in a loop. I closed that part off with the main house water valve. Very very happy with it as my house would be uninhabitable without running water. It's not fun filling toilets with river water from a bucket.

I use this pump on the farm to fill water troughs. Pumps well and even has a high pressure shut off.

The media could not be loaded. I’m using this pump to water plants on my deck with rainwater collected in barrels. DO NOT make the mistake I made. DO NOT ADJUST THE FLOW PRESSURE SCREW BEFORE SET UP AND FIRST TRIAL!!! I made a test setup with a bucket of water and the flow seemed just ok. I adjusted the screw and was almost ready to return the pump. Instead I read the instructions (which are not at all reader friendly) and the next day attempted to put the screw back into its original position (or as close as I could remember it being.) The pump works like a charm. Pump power is sufficient to drive water through nozzle. Pump quality seems to be holding up well. I plan to drain it and put a freeze cover over it for the winter. Pump build quality is on par with other similar pumps. I wish the connections were brass rather than plastic. The garden hose connection adapters which were included are brass. Leaks are too easy to occur when threaded plastic meets threaded brass. Overall I’m happy with the price and quality and supposed support from the manufacturer (which I haven’t had to use, but is spelled out in the owner’s manual). We’ll see how it holds up being stored throughout the winter and firing up again next spring. NOTE: Keep the box in storage. I recall reading in another review that if you do have to return it to the manufacturer for warranty service, they request the original packaging.
