Questions and answers
Leaking from the bottom ring
The manual does not provide specific instructions for fixing a leak from the bottom ring of an ACV COMFORT 45. However, general troubleshooting steps include:
1. Inspect the Source – Check if the leak is coming from a pipe connection, the drain valve, or the tank itself.
2. Tighten Connections – If the leak is from a fitting, ensure all connections are properly tightened.
3. Check the Drain Valve – Ensure the drain valve is fully closed and not leaking. If faulty, replace it.
4. Examine the Inner Tank – If the inner tank is leaking, it may indicate internal failure, requiring professional inspection or replacement.
5. Verify System Pressure – Ensure the system pressure does not exceed 15 psig before draining the inner tank, as recommended in the manual.
If the issue persists, contact a qualified technician for further diagnosis.
