Water Heater Information and Recommendations

For safety purposes, keep the temperature of your water heater dial set at or below the recommended factory setting listed on the water heater or in the handbook. Beyond that setting will substantially increase the potentiality for scalding.

All water heaters are mandated by law to be outfitted with a temperature and pressure relief valve (t & p valve) as a safety component to avoid damage from excessive pressure > 150 psi or temperature > 210 degrees. If the t & p valve is expeling water you should call your plumber immediately.

Flushing your water heater

This is something that thing that ought to be undertaken on a routine basis.

Here is a video about how to do this.  Below is a written description.



The procedure is as follows:

- Hook a garden hose up to the lower drain valve. Place the garden hose in a position to permit total discharge of the water through the hose (into a floor drain, bath tub or street). NOTE: THIS WATER WILL BE BLISTERING AND IS A SCALD DANGER! THE TEMPERATURE MAY WELL KILL PLANTS.


- Run the water out of the hose till the water runs clear (generally just a few seconds).

- Once the water is clear, shut off the bottom drain valve and remove the garden hose.

How many years do water heaters last?

The answer is not simple. While the average life expectancy for water heaters is around 12 years, numerous things can affect the lifetime of a water heater.

* Water softeners are made use of to reduce hardness in water, they can lessen the life of water heaters by consuming the anode rod quickly (commonly within one year). Once the anode rod is consumed there is no protection system in the water heater to prevent the water from dissolving the seam joints. Anytime a water softener is installed the water softener will need to be bypassed annually to permit some lime to accumulation to preserve the heater and decrease the anode rod consumption

* Thermal expansion can easily create very high pressures and normally manifest itself by untimely breakdown of the water tank or leaking t & p relief valves. Thermal expansion is normally only a problem on a closed plumbing system.

*The under sizing of water heaters makes them to be "on" much more frequently than a correctly sized water heater. This will cause parts to go downhill much more rapidly than expected.

* Mineral deposits and buildup inside water heaters are destructive and act as an insulator involving the heat source (burner or elements) and the water, leading to the water heater to work harder to keep the temperature.

* Missing anode rod because of water quality or elimination of anode rod.

If you have a question or worry about any one of these issues involving your water heater, you ought to call your plumber.
