Installation
The Wellmate WM-9 / WM0120 tank is designed for quicker and less costly installation compared to traditional steel tanks. However, proper installation is crucial for optimal performance and safety. It is highly recommended that installation be performed by a qualified professional in accordance with all local plumbing codes and regulations. Ensure the tank is placed on a level, stable surface and that all connections are secure and leak-free. Do not over-pressurize the tank during initial setup.
Operation
The Wellmate WM-9 / WM0120 tank functions as a crucial component in your water pressure system, storing water under pressure to provide a consistent flow and reduce pump cycling. Once properly installed and charged, the tank operates automatically with your well pump system. Monitor your system's pressure gauge regularly to ensure it operates within the recommended range. Avoid tampering with the factory-set air charge unless performing maintenance as instructed.
Maintenance
Wellmate tanks are designed for minimal maintenance. A key feature is the replaceable air cell, which assures easier field servicing should it ever be required. Regular maintenance should include:
- Annual Air Charge Check: Verify the tank's air pre-charge annually using a pressure gauge. The pre-charge pressure should be set according to your pump's cut-in pressure, typically 2 PSI below the pump's cut-in setting.
- Visual Inspection: Periodically inspect the tank for any signs of external damage, leaks, or corrosion.
- Connection Integrity: Check all plumbing connections for tightness and signs of leaks.
For detailed instructions on replacing the air cell or other specific maintenance procedures, consult a qualified technician or the official Wellmate service guide.
Troubleshooting
If you experience issues with your water pressure system, consider the following common troubleshooting steps:
- Low Water Pressure: Check the tank's air pre-charge. A low pre-charge can lead to reduced system pressure. Also, inspect for any leaks in the plumbing system.
- Pump Short Cycling: If your pump turns on and off frequently, it may indicate a loss of air pre-charge in the tank or a ruptured air cell. Verify the air charge and inspect the air cell.
- Waterlogged Tank: A tank that feels heavy and contains water when the system is depressurized likely has a compromised air cell. This requires air cell replacement.
For persistent problems or issues beyond basic troubleshooting, contact a certified well system technician.
