Hello,
Have a Bradford-White water heater and am looking to drain it. Shower caulk has some yellow stain on it coming from shower water, suggesting that maybe hot water tank has mineral deposits, hasn't been drained in a few years.
The steps outlined in the manual are:
1. Rotate the thermostat dial clockwise to the lowest possible position.
2. Rotate and partially depress gas control knob clockwise to the “OFF” position.
3. Shut off the gas supply to the water heater ----- I might skip this step
4. Close the cold water supply shut-off valve.
5. Open the drain valve on the water heater by turning the knob counter-clockwise. The drain valve has threads on the end that will allow the connection of a standard hose coupling.
6. Open a hot water faucet to allow air to enter the system ----- why do we need to do this?
Then after water is drained, the fill steps are:
1. Close the water heater drain valve by turning the knob clockwise .
2. Open the cold water supply shut-off valve.
3. Open several hot water faucets to allow air to escape from the system.
4. When a steady stream of water flows from the faucets, the water heater is filled.
Close the faucets and check for water leaks at the water heater drain valve, combination temperature and pressure relief valve and the hot and cold water
connections
But the manual now has something as a Warning
Wait at least 2 minutes after this control is pressurized with gas before attempting to light pilot and/or push igniter button. Failure to do so may result in serious injury.
What the heck does this refer to in the steps for Draining and Filling Tank?
Any inputs/suggestions/advice on things to look out for before starting on this?
Thanks
