cowl.
The Building Regulations, Document H1 sub
section 1.31, stipulates that any soil and vent
pipe installed externally within three metres of
any opening window, is required to terminate
a minimum of 900mm above the window.
This new development to the traditional
internal Air Admittance Valve allows a
soil stack fitted with an external Air Admittance
Valve to terminate within three metres of a
window opening. This allows the pipe to
terminate at the same height as if it were
installed internally i.e. 200mm minimum above
the highest wet entry point to the soil vent pipe.
(diagrams a & b).
The use of an external Air Admittance Valve
eliminates the need for the installer to work and
handle pipe above the roof line, making it
easier to comply with Work at Height (WAHR)
and Manual Handling Regulations.
