The average homeowner just assumes that their water heater is providing them with potable water. Unfortunately, this misconception is rarely brought to their attention until it is too late and they find out that they have been drinking contaminated water, sometimes for years.

Water heater systems are mechanical devices and they do break down at times. Poorly maintained or constructed water heaters can lead to a variety of problems including poor quality water.

As a responsible water heater owner, you need to carry out a regular program of water heater maintenance. Good maintenance means testing your water regularly, keeping the water heater area clean and accessible, keeping pollutants as far away from the area as possible and periodically having the mechanics of the water heater system checked.
