Customer called in about not getting hot water in his kitchen faucet. Getting cold water just fine. Customer has copper throughout the house but does live in an older part of town. Was able to back feed water pressure through the cold side and dislodged sediment. Customer made mentioned of constantly having to clean aerators to remove sediment. Customer does not currently have a water treatment system. Recommended to customer at least getting a sediment filter to help fight sediment issues. Customer would like different options on water treatment system.
