Frequently Asked Questions
The new standard temperature that manufacturers use when pre-setting your hot water heater at the factory is typically 120°F. This is a sufficient temperature for most households. If you have an older model, you can set the thermostat at medium. Gas models usually have a dial on the front of the gas valve. Electric models have thermostats (there may be two) that are concealed behind the two panels on the side of the tank. You can adjust the temperature to meet your needs. Keep in mind that hot water also helps in minimizing the growth of bacteria. Consult Reliable Water Heaters on (510) 372 6672 for the recommended temperatures for your particular needs.
Rumbling sounds can be an indication that sediment has built up on the bottom of the water heater. Water can become trapped in this sediment and begin to boil. This means the Water Heater is not operating efficiently and the sediment isn’t allowing the heat to transfer to the water in the tank. You may try draining a few gallons of water off the bottom of the Water Heater tank. This is done by attaching a drain hose to the valve at the bottom of the tank. Allow it to drain for about five minutes. Many newer models of water heaters have a new feature that prohibits the buildup of sediment in the tank. If your heater is an older model, it may be cost effective to replace the water heater if the buildup is severe.

Yes, you should test the pressure relief valve regularly and replace it if it fails to operate. At least once a year you should flush out the sediments. As long as a tank has a functioning anode, it should not rust. Therefore you should have the anode checked by Reliable Water Heaters professional about once every year.
- 1 - TURN OFF GAS OR ELECTRICITY      Gas           : Twist the dial on the top of the thermostat from the ON to the OFF position.
Electricity : Switch the circuit breaker for the water heater to the OFF position.
- 2 - TURN OFF WATER SUPPLY      Turn the handle on the water valve CLOCKWISE until it stops. If the water does not stop, turn off the main water valve for the entire house.
- 3 - DRAIN WATER HEATER       Attach a hose to the drain valve at the bottom of the tank. Run the other end of the hose to a lower place where you can drain rusty,
hot water without causing damage. Open a hot water faucet in the house to let air into the tank.
- 4 - OPEN THE RELIEF VALVE       Flip handle so it is sticking straight out or up. (CAUTION: Scalding hot water).
