As a homeowner, you can perform simple routine plumbing maintenance to extend the life of a water heater. For example, you should drain the water from your heater once or twice a year to flush out sediment. If not removed, sediment can build up in the tank, causing rust and damage. You can also add a water softener to your system to reduce the mineral content and prevent scale build-up. In addition to these simple steps, don’t hesitate to contact a professional for expert advice and assistance.
