We just replaced our hot water heater because we were getting a lot of mineral deposits in our fixtures throughout the house because the hot water loop returned to the bottom of the tank and always mixed up the sediment in the tank. Our plumber is trying to install a recirculation pump without using the drain valve (at the bottom of the tank) as the return for the loop. He is trying to explain to me how putting a pump in different places can circulate the hot water through the house and back into the hot water heater. Is this even possible?
Here is the current setup, which isn't really working. Inconsistent water temperatures, and some times little to no hot water.
Thanks for your help!!
