Is the cold water safe to drink if the circulating pump is mixing the cold line with water from your water heater? Or do you need to run the cold water for a minute before drinking, to flush the line?
Hey there, if you are referring to hot water bleeding over to the cold side at the tap where a comfort valve is installed, then yes, the water is safe to drink. The pump should be installed on the hot water line and is not involved in mixing water from the hot and cold lines. Hope that helps! -Ty
@@grundfosThank you! Yes I was told by a plumber that you should not drink water coming from your water heater because of the contaminants in the water heater tank. That being said I was concerned where the warm water travels down the cold water line at the comfort valve that those contaminants are now being transferred to the cold water line.
Hello, without a return line, that can be a consequence of a recirculation pump. However, our latest solutions have been built to minimize that warm water.
Hi, please help, i'm seeking for a pump to circulate water, i have not a dedicated return line and i have a tankless heater water, whiche pump d i choose ? Thks
Hello there, it sounds like you would want to look at the ALPHA Comfort System for those without a dedicated return line. We would recommend reaching out to a local licensed installer to help. Here is the link to the pump itself: gfos.ly/6051SdclH

So, without a return line, the cold water line will be hot, while recirculating?
Correct

@@grundfosWhat is your latest solution? Bypass valve sensor? I want to learn as I do not have dedicated return line.
@@grundfosI have a tankless water heater without a return line. What is the solution?
