Common Combi Boiler Draining Problems
Draining a combi boiler system can be straightforward, but several common issues may arise during the process. Understanding these potential problems is crucial for ensuring a smooth operation and preventing damage. This section highlights frequent challenges encountered when draining a combi boiler and offers insights into how to effectively address them.
Sometimes, issues may arise during the draining process. Understanding these can help you address them effectively.
Water not draining: Check if the drain valve is fully open. If not, adjust it accordingly.
Airlock: If water flow stops, it may indicate an airlock. Open a radiator bleed valve to release trapped air.
Leakage: If water leaks from the hose connection, ensure the hose is securely attached.
