ZAOJIAO DC 12V Home Brew Little Pump, Solar Hot Water Circulation Brushless Pump 780L/H 206GPH 5M/16ft Low Noise + 10ft Food Grade Silicone Tubing + ETL Listed DC Power Supply Adapter

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

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

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.

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.

This is not a self priming pump and takes a little practice for efficiency. No on/off switch but I have it plugged into a power strip with a switch. I added a small ball valve at the outlet of the hose to help reduce the sparse water. The hose is a little thin and can kink if you are not careful but for the money it’s an awesome buy and makes brewing even easier. My setup currently is a 3.5 gallon SST pot of a small single propane burner (already had both) and the hot water pump to rinse the grain in our electric Brewer’s Edge Mash & Boil that has its own recirculating pump built in. Prost!

Work great until it didn't. Stopped working a few days before the return window so hopefully seller sees this and sends me a replacement. Maybe a bad batch off the assembly line so who knows.

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.

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.
