John Guest 15mm Filling Loop With Integral Check Valve

Reliance Filling Loop is a pipe connection to a central heating system 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. The 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 Category 3 contamination risks, the filling loop has been designed with 15mm compression connections, thumb-grip nuts on the hose and a ball valve for easy operation and installation. It also comes with an integral check valve and isolator.
