Make Up Water
Provision must be made for replacing water lost from the sealed system. Reference should be made
to BS6798, for methods of filling and making up sealed systems. There must be no direct connection
between the boiler's central heating system and the mains water supply. The use of mains water to
charge and pressurise the system directly, is conditional upon the Local Water Byelaws. Again any such
connection must be disconnected after use. Ensure the filling point is on the return pipe to the boiler.
Attention - is drawn to the Model Water Byelaws.
Key
1. C.H. filling valve.
