Filmaster® Filling Loop

The Filmaster Filling Loop is pipe connection to a central heating system in order to re-fill or re-pressurise the system from the mains water supply. The boiler filling loop feeds water back into the system and is detached once the system has been filled to the adequate pressure.

A filling loop is not part of the boiler system and is detached ready for re-use after each use. Both connections on the pipe are fitted with valves to allow the user to easily cut off the water supply and disconnect the pipe.

Protecting against class 3 contamination risks, the Filmaster Filling Loop has been designed with 15mm compression connections, thumb-grip nuts on the hose and a ball valve for easy operation & installation.
