Quick Answer
A bladder tank not holding air can be due to a leak in the diaphragm or a faulty valve, or it may be over-pressurized or under-pressurized, causing the air to escape. To troubleshoot, check for leaks, inspect the diaphragm, and adjust the pressure setting.
Inspect the Bladder Tank and Diaphragm
Inspect the bladder tank and diaphragm for any signs of damage, wear, or corrosion. Check for any holes, tears, or punctures in the diaphragm, and inspect the valve stem and O-ring for any signs of wear or damage. Use a pressure gauge to check the tank’s pressure and compare it to the manufacturer’s recommended pressure range.
Check for Leaks and Adjust Pressure
Use a soap solution or a pressure test kit to check for any leaks in the tank, valve, or connections. If a leak is found, repair or replace the affected component. If the tank is under-pressurized, adjust the pressure setting to the recommended range. If the tank is over-pressurized, reduce the pressure setting to prevent damage to the tank or diaphragm.
Adjust the System for Optimal Performance
Once the tank is pressurized within the recommended range, check the system’s performance. Ensure that the pump is set to the correct cycle rate and that the tank is sized correctly for the system’s demand. A properly sized tank should hold 2-3 gallons of air per gallon of water. If the tank is undersized, consider upgrading to a larger tank to ensure optimal system performance.
