I have a question about the bronze pump recirculation pump I understand that you use that with a on-demand tank and that little device under the farthest sink so you're not wasting the water in the pipe going down the drain it push it through to the cold side I have two questions question number one can I put a recirculation pump and that little device on a regular conventional hot water tanks number two when you open the hot water valve doesn't the water meter still run when it's pushing water through to the other side if so there's really no death there will be no difference between using a recirculation pump versus just letting it run down the drain if you're still getting charged from your water company.
