Steps to Replace a Water Pressure Tank

1. Preparation:

   • Make sure you have a new tank that matches the specifications of your old one.
   • Gather necessary tools like pipe wrenches, Teflon tape, and a bucket.
   • Turn off the power to the well pump circuit breaker.
   • Shut off the main water supply to the house.
   • Drain the entire system by opening faucets.

2. Disconnect the Old Tank:

   • Use a wrench to disconnect the water line from the old tank.
   • Carefully detach the electrical connections, if applicable, marking each wire to ensure correct reconnection later.
   • Loosen the pressure switch connections and detach them.

3. Prepare the New Tank:

   • Inspect the new tank for any damage during shipping.
   • Apply Teflon tape to the threads of the tank connection points.

4. Install the New Tank:

   • Carefully position the new pressure tank where the old one was.
   • Thread the water line onto the elbow connected to the tank. Ensure it faces directly up to meet the coupling.
   • Thread the coupling together and tighten it up.

5. Reconnect Components:

   • Reattach the pressure switch and electrical connections, ensuring they match the original positions.
   • Ensure all connections are secure, and all fittings are properly tightened.

6. Recharge the System:

   • Slowly turn the main water supply back on.
   • Keep the water running to remove air pockets from the system.
   • Turn the power back to the pump after the system has been recharged.
   • Check for leaks and address them immediately if any are found.

Important Notes:

• Safety First: Always disconnect power before working on electrical components.
• Proper Tools: Use the correct tools to avoid damaging the tank or connections.
• Check Tank Pressure: Verify the pre-charge pressure in the new tank matches the system requirements. Adjust if needed.
