Review: I gambled and lost ,so i thought! - worked great for ten minutes. then stopped working. after messing around with it I found the limit switch was not working. When i jumped it out and took it out of the circuit the pump ran. I ended up bypassing the original switch and worked out a switch of my own. I use it with a spray wand for spraying plants etc. I bought it because it was cheap. That's my fault. I will buy a better pump to replace this one. I have changed my review since i bought this item and had a failure and wrote the above 2 star review but since changed it to 5 star. The company reached out to me through desertcart and apologized for the product not working properly and for the inconvenience. This was totally unsolicited and quite a surprise to me. They offered me a complete refund which i shortly received. They stand behind their product and that level of customer service is quite rare these days. I was very impressed. There is no gamble purchasing from this company Review: What a small Great Pump - Got it last week..Very happy with this Product..powerful..working nicely...and thanks for the Fast Delivery....5star ## Features - The patented design delivers smooth & consistent flow at all ranges of operation, while drawing low current - Inlet and Outlet: 3/8-inch hose barb ports.

If there is any problem with our product, please feel free to contact us through clicking the link of " ask seller" in your order details and I can reship you another new replacement free of charge and there is no need to return anything. **Q: Does this have an AC plug?** A: No ac plug **Q: Can you pump motor oil, or diesel with it?** A: No. This motor can't be used for Flammable liquid. **Q: Will this punp create enough pressure for an 80’ tube misting system?** A: 80 psi of water pressure is equal to about 2200 inches (183feet) of vertical height, of course the higher you pump the greater the pressure drop. For example: 0ft of height is 80psi, 92ft of height is 40psi, and 183ft is 0psi. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I gambled and lost ,so i thought! *by M***O on 4 April 2026* worked great for ten minutes. then stopped working. after messing around with it I found the limit switch was not working.
