Step 4: Remove the Old Water Heater
Getting the old one out!

- Tighten the nuts securely using an adjustable wrench.
Step 7: Fill and Bleed the Water Heater
Let’s get some hot water flowing!

- As the water heater fills, open the hot water taps at the highest points in your home to release any trapped air.
- Once water flows smoothly from the taps, close them.
Step 8: Restore Power
Time to power up!
- For an electric water heater, turn on the circuit breaker.
- For a gas water heater, light the pilot light according to the manufacturer’s instructions.
Step 9: Check for Leaks

- No hot water: Check if the power is on, the pilot light is lit, and the water supply is turned on.
- Leaking water: Tighten the fittings or apply more plumber’s putty.
