Your water heater is required to work more during winter months. It is recommended to it flush it out and remove any sediment buildup. The buildup can cause corrosion, shorten the life span, and reduce heating efficiency. Remove several gallons from the faucet near the bottom of the tank. To do that connect a hose to the faucet at the bottom and remove several gallons to a drain or bucket. Call Schepers with any questions. 616-669-2210.
