Maintaining a well-functioning water system is crucial for any homeowner who relies on a private well for their water supply. A key component of this system is the well pressure tank, which plays a vital role in providing consistent water pressure throughout the household and ensuring the efficient operation of appliances that rely on water. Over time, however, these tanks can deteriorate and require replacement, often leaving homeowners wondering how to tackle this task effectively.
Replacing a well pressure tank is a project that requires careful planning and attention to detail. Before embarking on this endeavor, it’s essential to gather the necessary tools and materials, including a new pressure tank, a tank tee, a pressure switch, and various plumbing supplies. Additionally, safety should be paramount, and all electrical connections should be handled by a qualified electrician. Once the preparations are complete, it’s time to embark on the step-by-step process of replacing the old pressure tank with a new one.
The first step involves isolating the pressure tank from the water supply and draining any remaining water. Next, the old tank is disconnected from the plumbing system, and the new tank is put in its place. Once the new tank is securely connected, the pressure switch is adjusted to the desired settings, and the electrical connections are made. Finally, the system is tested for leaks, and the water supply is restored, bringing the replacement process to its successful conclusion.
Disconnecting the Electrical and Water Connections
### Electrical Connections
Before disconnecting the electrical connections, turn off the circuit breaker or fuse that supplies power to the well pump. Locate the electrical panel and identify the circuit breaker or fuse labeled “Well Pump.” Turn it off and verify that the power is off at the pump.
Next, disconnect the wires from the pressure switch. The pressure switch is usually mounted on the side of the well tank. There will be two wires connected to the pressure switch: one from the power source and one to the pump. Use a screwdriver to loosen the screws that hold the wires in place and disconnect them.
### Water Connections
To disconnect the water connections, you will need a wrench or pipe wrench. Start by closing the water supply valve that is located on the pipe that enters the well tank. This valve is usually located near the top of the tank.
Once the water supply is shut off, disconnect the water line from the tank. There will be two water lines connected to the tank: one from the well and one to the house. Use a wrench or pipe wrench to loosen the nuts that hold the water lines in place and disconnect them.
Drain the Tank
After the electrical and water connections are disconnected, you can drain the water from the tank. Open the drain valve at the bottom of the tank and allow the water to drain out. Be sure to have a bucket or hose ready to catch the water.
| Pressure | Capacity | Size | |
|---|---|---|---|
| Tank 1 | 40/60 PSI | 20 Gallons | 24″ x 12″ |
| Tank 2 | 30/50 PSI | 30 Gallons | 30″ x 15″ |
Removing the Old Tank
Before detaching the tank, it’s crucial to depressurize the water system by turning off the pump and opening a faucet to release the remaining pressure. Next, proceed with these steps:
- Disconnect the Plumbing: Using a wrench, disconnect the water supply line, pressure switch, and drain valve from the old tank.
- Remove Electrical Wires: Carefully disconnect any electrical wires attached to the pressure switch or the tank itself.
- Support the Tank (Optional): If the tank is heavy or awkwardly positioned, use a jack or support beams to prevent it from falling while you disconnect it.
- Unbolt the Tank: Locate the bolts that secure the tank to its base or brackets and remove them. Be cautious as the tank may be filled with residual water.
- Prepare for Water: Have a bucket or towels on hand to catch any water that may drain from the tank or piping during removal.
- Remove the Tank: Gently lift and pull the tank off its base or brackets and set it aside. Be prepared for some water to spill out.
Tip: If the tank is rusted or stuck, use a penetrating oil or lubricant to loosen the bolts and ease its removal. Additional Notes:
– If possible, leave the old tank fully connected until you have the new tank ready to install. This allows you to easily compare the connections and ensure everything lines up correctly.
– If you encounter any difficulties or the tank is particularly heavy, do not hesitate to seek assistance from a qualified plumber.Reattaching Electrical and Water Connections
Once the new tank is in place, it’s time to reattach the electrical and water connections.
Electrical Connections
- Turn off the power to the well at the breaker panel.
- Disconnect the wires from the old tank and label them so you can easily identify them later.
- Connect the wires to the new tank in the same configuration as the old tank.
- Turn on the power to the well.
Water Connections
- Connect the water inlet pipe to the new tank.
- Connect the water outlet pipe to the new tank.
- Close the valves on both the inlet and outlet pipes.
- Open the bleeder valve on the new tank to release any trapped air.
- Open the valve on the inlet pipe to allow water to fill the tank.
- Once the tank is full, close the bleeder valve.
- Open the valve on the outlet pipe to allow water to flow to the house.
Bleeder Valve Procedure
The bleeder valve is used to release any trapped air in the tank. This is important because air can cause the tank to malfunction. To use the bleeder valve:
Step Description 1 Open the bleeder valve by turning it counterclockwise. 2 Allow water to flow out of the bleeder valve until it is free of air. 3 Close the bleeder valve by turning it clockwise. How to Replace a Well Pressure Tank
Replacing a well pressure tank is a relatively simple task that can be completed in a few hours. By following these steps, you can ensure that your well system is operating properly. Below is a comprehensive guide on how to replace a well pressure tank:
Tools & Materials
- New well pressure tank
- Wrenches
- Pipe sealant
- Electrical screwdriver
- Teflon tape
- Measuring tape or ruler
Steps
1. **Shut off the power to the well pump.** This can be done by turning off the circuit breaker or fuse that supplies power to the pump.
2. **Turn off the water supply to the house.** This can be done by closing the main water valve.
3. **Release the pressure in the water lines.** Do this by opening a faucet in the house.
4. **Disconnect the pipes from the old pressure tank.** Use a wrench to loosen the nuts on the pipes.
5. **Remove the old pressure tank.** Once the pipes are disconnected, the tank can be removed by lifting it off its base.
6. **Install the new pressure tank.** Place the new tank on the base and connect the pipes. Tighten the nuts on the pipes and apply pipe sealant to prevent leaks.
7. **Turn on the water supply to the house.** Open the main water valve slowly to avoid water hammer.
8. **Turn on the power to the well pump.** The pump will start to fill the pressure tank with water.
9. **Adjust the pressure switch.** The pressure switch controls the pump’s on and off cycles. Adjust the pressure switch to the desired pressure range.
10. **Test the system.** Once the pressure switch is adjusted, test the system by running water from a faucet in the house. The pump should turn on and off as needed to maintain the desired water pressure.
