The hot water line throughout the house is equipped with a recirculation return line that enables the occupants of the home to receive instant hot water at any faucet in the home. On the previous invoice, it was listed that the recirculation pump does not have a timer and was constantly running 24/7. With this pump running all the time, The lifespan of the copper piping used in the hot water and recirculation line is greatly reduced. On the last visit here, Southside Plumbing unplugged the pump to prevent any further damage However, the inside of the line already has damage done. The recirculating line was already repaired above the kitchen and now a leak has started behind the refrigerator. These leaks are a result of the damage done by the recirculation of water through the lines. The bad section of piping can be repaired using Pex piping to replace the bad section of pipe. The piping being replaced is going through the floor into a wall space above.
