Water heater preventive maintenance I should remember

When properly maintained, the water heater will provide years of steady trouble-free service. It is advised that a routine water heater preventive maintenance program be practiced and followed by the user.

Here is an example of a list water heater owners should remember to do.

• At least once a year, lift and release the lever handle on the temperature-pressure relief valve. It can be found on the side of the water heater. This is to make sure that the valve operates smoothly. Let several gallons of water flush through the discharge line to an open drain.
  • DANGER: Before manually turning the relief valve, make sure that no one will be exposed to the danger of coming in contact with the hot water released by the valve. The water may be hot enough to create a scald risk. The water should be released into a suitable drain to prevent injury or property damage.
  •  If the temperature and pressure relief valve on the water heater discharges regularly, this may be due to thermal expansion in a closed water system. Contact the water supplier or your plumbing contractor on how to correct this. DO NOT plug the relief valve outlet.
• When the “Clean Filter Reminder” warning appears, clean it by washing with mild detergent and water. Dry and replace. Remove the filter by lifting it up, then replace it by lowering back into the filter slot on top of the unit.
• At least once a year pour a cup of bleach in the access opening of the condensate drain. By doing this, it will kill any algae, mold, or mildew that has formed in the pipe. Ensure the condensate can flow freely; unclog if needed.
• A water heater’s tank can act as a settling basin for solids floating in the water. It is not surprising for hard water deposits to accumulate in the bottom of the tank. It is encouraged that a few quarts of water be drained from the water heater’s tank every month. This is to clean the tank of these sediments.
• Rapid closing of taps or solenoid valves in automatic water using appliances can cause a banging noise heard in a water pipe. Strategically located risers in the water pipe system or water hammer arresting devices can be used to reduce the problem.
• Most electrical appliances, even when new, make some sound when in operation. However, if the hissing or singing sound level increases excessively, contact a qualified installer or plumbing contractor to inspect.
