Possible Causes
Excessive inlet pressure, Blocked outlet, Thermal expansion without relief, Incorrect tank rating for system pressure
How to Fix / Troubleshooting
Safety: Immediately shut off water and depressurize the system. A deformed pressure vessel can be dangerous.
- Depressurize: Close inlet and outlet valves and open a downstream tap to relieve pressure.
- Inspect tank rating: Check the Idrobase tank label for maximum working pressure and compare to system pressure.
- Check for blockages: Ensure outlet valves and downstream plumbing are not blocked or closed.
- Install protection: Fit a pressure reducing valve and expansion vessel if system pressure or thermal expansion is high.
- Replace tank: Do not continue using a visibly deformed tank. Replace the resin tank with a new, correctly rated vessel.
