Understanding and Diagnosing Faults in Your WellMate 80-Gallon Pressure Tank
The WellMate WM-23, an 80-gallon composite pressure tank, offers reliable performance in demanding well systems. However, like all equipment, it can develop faults over time. Recognizing these issues early and understanding their causes can save you time, money, and prevent system failures. This guide explores the most common faults found in WellMate pressure tanks and provides practical solutions for diagnosing and fixing them effectively.
Common Faults in WellMate Tanks
1. Loss of Pressure
One of the most frequent issues is a gradual decline in pressure within the tank. This often manifests as inconsistent water delivery and frequent pump cycles.
Possible Causes:
- Leaks in the tank or plumbing connections
- Degradation or loss of the internal air charge
- Damaged or failed air cell
- Waterlogged tank due to a compromised bladder or air chamber
2. Pump Short Cycling
Frequent cycling of the pump can indicate a loss of the pre-charge pressure or an internal tank fault, leading to increased energy consumption and equipment wear.
Possible Causes:
- Low or no pre-charge pressure
- Air cell damage or failure
- Incorrect tank size relative to system demand
3. Waterlogging and Noisy Operation
If you notice a persistent knocking sound or the tank feels unusually heavy, it might be waterlogged.
Possible Causes:
- Failed or degraded air cell allowing water to fill the entire tank
- Leaks or structural damage within the tank
4. Air Escaping or Excessive Pump Cycles
Air escaping from the tank can cause cycling issues, pressure fluctuations, and increased pump wear.
Possible Causes:
- Damaged or degraded replaceable butyl air cell
- Leaks around fittings or connections
Diagnosing Faults
Step-by-Step Troubleshooting
- Check the pressure: Use a pressure gauge on the system's pressure port to verify the pre-charge and operating pressure. Typically, the pre-charge should be around 2 psi below the pump cut-in pressure.
- Inspect for leaks: Examine the tank and all fittings for signs of water or air leaks. Pay close attention to the quick connect fittings for any looseness or damage.
- Listen for noises: Knocking or banging sounds can indicate waterlogging or internal component failures.
- Assess the weight of the tank: A waterlogged tank often feels much heavier than normal.
Fixing Common Issues
Restoring Pressure and Fixing Leaks
If the pressure is low, it may be necessary to recharge the system with air, following manufacturer guidelines. For leaks, tighten fittings or replace damaged components.
Replacing the Air Cell
The WellMate’s replaceable butyl air cell is designed for easy replacement if it fails or degrades. This process involves draining the tank, removing the old air cell, and installing a new one, restoring internal pressure and preventing waterlogging.
Dealing with Waterlogging
If the tank is waterlogged, draining and replacing the air charge often resolves the fault. If internal damage is suspected, a full inspection or tank replacement may be necessary.
Regular Maintenance Tips
- Periodically check system pressure and top up the pre-charge if necessary.
- Inspect fittings and connections for leaks or corrosion.
- Monitor the sound and weight of the tank for signs of waterlogging.
- Schedule professional servicing if faults persist or worsen.
Conclusion
Understanding the common faults that can occur in your WellMate 80-gallon pressure tank empowers you to diagnose issues effectively and undertake basic repairs. Regular inspection and maintenance can prolong the life of your system, ensure steady water pressure, and minimize costly repairs. If problems persist beyond basic troubleshooting, consulting a professional is recommended to avoid further damage and ensure your water system operates at peak performance.
Getting the Most from the System
To extend the life of your WellMate 80-gallon pressure tank and improve overall system performance, adopt certain operating habits. Regularly check the pressure settings and maintain the appropriate pre-charge pressure to ensure the tank functions optimally. Monitor water usage patterns and avoid excessive demand. This can help minimize the risk of pump short cycling and extend the lifespan of both the pump and pressure tank.
Additionally, consider scheduling routine maintenance checks for the entire water system. Inspecting connections, valves, and the tank itself for leaks or signs of wear can help catch problems before they escalate. Properly maintaining the air charge and ensuring the bladder remains intact will also contribute to efficient operation and consistent water delivery.
