Review on Efficient 12V Solar Water Heater Circulation Pump with Low Noise - bayite BYT-7A015 by Dontra Majmudar

Used to push and circulate wort (brewing) through the counterflow cooler. Did a test and it works great. I can't submerge it in water because the initial temperature is close to boiling, so it needs to be connected to the ball valve at the bottom of the kettle. It would be great if it could even be slightly self-priming, but it isn't. For the price if it lasts a few years it would be a good investment. Update - There was a problem with the pump. Sometimes it didn't start. I found that sometimes when I tapped it, it would run. On other occasions I opened it up and spun the impeller with my finger and it worked. I contacted the company and they immediately backed up their product and replaced the device. Can't ask for more.
