4.6.6 Anti vacuum valve
An Anti-vacuum valve must be fi tted to prevent a vacuum forming in
installations where there is the potential of the draw off rate exceeding
the rate of fl ow to the inlet; this can occur in properties with multiple
outlets below the base of the hot water heater. The valve contains a
check cartridge which under normal conditions is held closed by the
system pressure.
When a vacuum condition exists, the suction will cause the check car-
tridge to open and air to fl ow through, equalising the pressure within
the hot water heater. The capacity of an anti-vacuum valve should be
equal to or greater than the rate of the vacuum formation in the vessel
being protected. An Anti-vacuum valve kit (part number 7799189) is
available from Andrews Water Heaters.
should be made to BS 853 cl 10.3 or to the capacities of the valve in
