STEP 2: SHUT OFF WATER SUPPLY
STEP 1: TURN OFF WATER HEATER
Note: Install a new water heater at this point if the existing water heater will not be used.
Follow the water heater manufacturer’s installation instructions. A drip pan with a drain
line to the outside of the building is required whenever water storage tanks are located
above living space.
For electric water heaters: turn off the circuit breaker and verify with a volt meter at the top of the water heater.
For gas water heaters: shut off the gas supply valve.
Shut the cold water inlet valve to the water heater. This is usually a ball or gate valve located near the top of the water
heater. Shut off water to the home at the main water shutoff.
STEP 3: CONNECT HOSE TO DRAIN BIBB
Connect a garden hose to the drain connection at the bottom of your water heater. Make sure discharge end of
the hose is in a safe place for hot water to flow. Open the drain bibb.
STEP 4: OPEN PRESSURE-RELIEF VALVE
As water heater is draining, open the pressure-relief valve on the side or top of the heater. When heater is empty,
remove hose, close drain bibb and relief valve.
