Safety Precautions
Before you begin, ensure you have taken the following safety precautions:
- Turn off the water supply to your home.
- Open a faucet to release any remaining water pressure.
- Wear safety glasses and gloves.
Step-by-Step Instructions
1. Locate the Expansion Tank
Typically, expansion tanks are installed in a basement, utility room, or attic. Look for a cylindrical tank with two pipes connected to it.
2. Isolate the Tank
Close the valves on both sides of the expansion tank. This will isolate the tank from the rest of the plumbing system.
3. Drain the Water
Place a bucket under the expansion tank. Open the drain valve at the bottom of the tank to drain the remaining water.
4. Disconnect the Pipes
Using an adjustable wrench, loosen the nuts connecting the pipes to the expansion tank. Be careful not to overtighten.
5. Remove the Old Tank
Once the pipes are disconnected, you can remove the old expansion tank by unscrewing it from its mounting bracket.
6. Install the New Tank
Wrap Teflon tape around the threads of the new expansion tank. Screw the tank onto the mounting bracket and tighten it using an adjustable wrench.
7. Reconnect the Pipes
Connect the pipes to the new expansion tank and tighten the nuts using a pipe wrench.
8. Open the Valves
Slowly open the valves on both sides of the expansion tank. Check for leaks and tighten the nuts if necessary.
9. Turn on the Water Supply
Turn on the water supply to your home. Check for any leaks or unusual noises. If everything is working properly, your expansion tank is successfully changed.
Troubleshooting Tips
- No water pressure: Ensure the valves on both sides of the expansion tank are fully open.
- Leaking expansion tank: Check the connections between the pipes and the tank. Tighten any loose nuts or replace the Teflon tape.
- Water hammer: Adjust the pressure in the expansion tank to the correct level.
In a nutshell: Empower Yourself with Plumbing Knowledge
Changing an expansion tank is a relatively straightforward task that you can easily accomplish yourself.
