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

So far so good. I bought this to replace my broken Aqua Hot boiler for my motorhome. The OEM pump was hundreds of dollars- so super cheap. Seems to be doing the job. I did need to get new 1/2” adapters to fit my Aqua Hot- but that is no fault of this product. Just saying if you are using this in the manner that I am.

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.

Worse than useless. This pump only lasted a couple of months pumping clear water. DO NOT BUY.

I ordered two, because one device came with brass fitting having no threads. I only briefly used one. It worked well. But for my use adaptation, I found out it did not work well. One reason being that the silicone hose bands easily when making rapid curvature. When it bands, it restricts the water flow. I did not want to let it burn out, so I returned it. But I only used it for a few minutes, before the hose bent, so I do not know anything about longevity of the device. But it did work under about 140-150 Fahrenheit degree load.

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

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

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

Worked only briefly. After that, it would not go on. The impeller moves slightly, but does not rotate unless you give it a little push from one of the ports. Unfortunately, too late to return.
