Quick, cold showers, and low water pressure are a major drag, but they aren’t the only reasons you should replace your old water heater as soon as possible. Sediment build up can occur in old water heaters, especially if you have not drained them regularly as recommended by the manufacturer. This can create an ideal environment for bacteria and other harmful organisms to grow, which compromises the safety of your water supply. Sediment buildup can also interfere with the heating process and make your equipment work extra hard to get water to desired temperatures. If you’ve noticed a spike in your energy bills, your old water heater could be to blame.
