Water Heater Maintenance
Every 6 months, open the drain valve at the bottom and let the water run into a bucket until the water appears clear. This should be approximately 5 gallons. This will prevent sediment from accumulating.
Every 12 months, test the temperature – pressure relief valve. Either press or lift the valve handle. Water will drain from the overflow pipe. If water doesn’t drain, shut off the water to the water heater, open a hot water faucet somewhere in the house in order to drain the hot water pipes, and then replace the pressure relief valve.
NOTE: If boiling water or steam is released from the valve or any hot water faucets, shut off the heater immediately. If there is ever a growling or rumbling sound, you should conclude the water heater is overheating and turn it off immediately.
Water Temperature – Gas Heaters
The normal water heater temperature is 150 – 160 degrees fahrenheit. If you don’t have a dishwasher, you can lower the temperature.
NOTE: If you have small children, a high temperature water can burn them. Adjust the temperature accordingly.
Temperature Not Correct
If the water is not as hot as indicated by the temperature control, and you think the control may be defective, turn on the hot water at a faucet and let it run for between 3 and 5 minutes. If the heater does not turn on, set the control to a lower setting and test again. If it continues to fail, you will need to replace the heater.
