DC 12V Solar Hot Water Heater Circulation Brushless Little Pump with ETL Listed DC Power Supply Adapter Low Noise 780L/H 206GPH 5M/16ft for Home Brewing Recirculation System

I use this to circulate water between my RV water heater and a roof-mounted solar water heat panel. Works great!

Didn't function as it should. Got it to empty a tank we have on the ground and it wouldn't pump the water

Very good little pump, will push water really good. Worth the money and built strong. Nice hose and connections included.

I realize this is listed as a circulation pump, but I expected a small suction head height. It has absolutely none. Be aware of that if you need to pump f.rom one tank to another or anything like that. Priming the pump doesn't work either. I'm actually using it in a closed system pump cool water through a heat exchanger so it,l work for me. The pump itself looks to be pretty cheaply built so I'm definitely leaving my system adaptable for a replacement. Didn't set my expectations too high at the price so I'm not disappointed

Holy moly this is the best pump ever! I use it to pump water from a well uphill to a storage tank for a cabin. It has strong enough lift capacity to go a 70ft length up a 15ft high incline. I use 1/2 inch tubing. The screw on fittings are standard NPT threads. 10 out of 10! Stronger than the "770 GPH" massive pumps twice its size. I plan to order several more in the future.

Worked ok, only lasted a year. Was used to recirculate water in a water table. Its output was lower than expected as well.

I used this in a water fountain that we’ve had for years that was custom made. The pump went out quite a while ago and I have had the absolute worst time finding a pump that would fit and was quiet enough to use. While this pump isn’t silent, the waterfall sound does hide the hum. The flow is perfect for my application, but I do not know how well it would do if you needed a lot of water pushed.

Works great, but is just not durable. I use it to circulate pool water for a solar heater during the day only in the summer on solar power. The first one lasted a little over 1 year and the second one lasted less than 1 year.
