  • Works well when attached to rain barrel
Size: 5.5GPM-70PSI-110V
I set up a couple of rain barrels in my backyard to irrigate my vegetable garden. I attached the rain barrels to a drip irrigation system. However, water pressure was so low that the drip irrigation system didn’t work. Then I did some research and found this pump on Amazon. Setting up was a breeze. Now the water pressure is so high that I ended up having to add a pressure reducing valve in my irrigation system. Everything is working perfectly now. I recommend this to anyone who has a similar problem. ... show more

  • Great Pump and Outstanding Customer Service!
Size: 4.0GPM-50PSI(Garden Hose Adapter)-110V
I bought this pump for my mother's garden to use with a 500-gallon water tank that collects rainwater. This little pump connects to a garden hose and has been working perfectly. Recently, we experienced an issue where the pressure switch started acting up and working intermittently. I contacted the Eco-Worthy support team through their support page and received excellent customer service. I inquired about purchasing a replacement pressure switch, and they generously sent us a new pump. Thank you, Eco-Worthy, for the amazing support and for standing behind your product! ... show more

  • Some quality issues, but overall good.
Size: 5.5GPM-55PSI-110V
I've had this pump for a little over a month now. About a week after the return window closed, it stopped working. There are two small black wires that run underneath the pump, which control the pressure on/off switch (Shown in picture). I managed to take apart that section and determined this was the cause of the issue. You can buy these switches online pretty cheaply, but the repair process wasn't exactly convenient or easy. That all being said, the pump performs exactly as described and runs pretty quietly. I live in a small rent house which had extremely low water pressure. This pump is connected to a water storage tank which now feeds the entire house. Low pressure issue solved. ... show more

  • Quiet, Strong, and Great Customer Service
Size: 4.0GPM-50PSI-110V
We use this pump for our dog grooming business, and it runs inside of our business near customers. It’s a very soft hmmm and increases the water pressure Significantly but also not too much that will burst any pipes. We reached out to customer support for questions And they were extremely helpful! Overall great experience! ... show more

I purchased a pump in October, 2023. The pump worked fine last year. It was quiet and dependable. I starting camping again in March of '24, and the pump had an issue. I contacted customer service and they were excellent. They fixed the problem and were true to their word. I would absolutely purchase again from Ecoworthy. They stand behind their products!! ... show more

  • Do not buy, faulty pumps
Size: 5.5GPM-55PSI-110V
I have never left a one star review on Amazon, but this product has earned it. Last year I bought this pump for use with my travel trailer. It worked great for 9 months and then failed. Since there is only like a 45 day warranty, I could not return it, so had to buy a second one. That second pump only lasted 2 weeks, and then failed. I sent it back for a replacement, and it was going to be received in 48 hours, but then it got delayed for unknown reasons and now I am waiting for a new shipping date, and after talking with two Amazon Customer Service reps over three days, I still do not have a shipping date of when I will receive the replacement. Do not buy this pump. ... show more

  • The little engine that could
Size: 4.0GPM-50PSI(Garden Hose Adapter)-110V
I've been using this with a smart plug to pump the grey water from my RV to the sewer (I have a cassette toilet). it does an excellent job and makes very little noise. The filter is a little annoying, so I just removed it. I watch what goes down the drain in my RV, so I'm not terribly concerned. If you don't, this wouldn't be a good application for the pump... the filter fills fast and it's hard to clean. ... show more

  • Temporary Use Only!
Size: 4.0GPM-50PSI(Garden Hose Adapter)-110V
Theses pumps work, and serve their purpose. Yet, only work for about three months with minimal to moderate usage. This was our second pump and has quit working just like the original.
