EXPANSION CONTROL VALVE
1.
The Expansion Control Valve shall have the same pressure rating as other valves used in the system.
2.
The pressure rating of the Expansion Control Valve maybe less than the rated pressure of the storage water heater but shall never exceed it.
3.
An isolating valve, gate valve, non-return valve or any other flow control device shall not be provided between an Expansion Control Valve and the
water
4.
The discharge pipes from Expansion Control valve shall
a)
never be joined together with other discharge pipes,
b)
led to a discharge point which is visible outside the building and in a position where the discharge from the pipe will not cause a nuisance and
cannot become blocked,
c)
installed in a manner that will obviate the development of water traps which could prevent the free return of air into the system,
d)
sized not less than the size of the outlet of the valve for which the pipe is intended, and
