FAQs
What is a filling loop used for?
A filling loop is used to safely connect the mains cold water supply to a sealed central heating system for the purpose of topping up or refilling the system with water.
Does this filling loop comply with water regulations?
Yes, it features an integrated check valve (non-return valve) designed to prevent the contamination of the mains water supply, which is a key requirement of water supply regulations.
What size pipe does this connect to?
This filling loop is designed for 15mm pipework, using standard compression fittings.
Can I leave this filling loop permanently connected?
No, filling loops should not be left permanently connected to the system. They are designed for temporary connection during filling and should be disconnected afterward. The dual isolation valves allow for easy disconnection.
What is the benefit of dual isolation valves?
The dual isolation valves provide complete control. You can use one to allow water in to fill the system and then close both to completely isolate the filling loop from both the mains supply and the heating system.
What material is the body of the filling loop made from?
The body components are made from robust brass, suitable for heating system applications.
Troubleshooting
Water leak from compression fittings
Ensure fittings are correctly aligned and tightened. If the issue persists, the olive or pipe may be damaged and require replacement.
No water flow when valves are open
Check that both isolation valves are fully open. Ensure the mains water supply is on and that there are no blockages in the pipework or filling loop.
Check valve not preventing backflow
This is a critical safety component. If backflow is suspected, the filling loop may be faulty and should be replaced immediately.
