The NABIC 175 Three Way Cock has been designed for use on vented hot water systems, to ensure there is a permanent connection from the boiler or calorifier to atomosphere. Fitting a NABIC 175 allows the use of a single common vent pipe, and permits continued operation of the system whilst maintenance is carried out on an individual unit.
