Note: The above table is based on copper tube. Plastic pipes may be of different bore and resistance.
Sizes and maximum lengths of plastic should be calculated using data prepared for the type of pipe being used.
pipe 9m long, i.e. for discharge pipes between 9m and 18m the
equivalent resistance length should be at least two sizes larger
than the nominal outlet size of the safety device; between 18
and 27m at least 3 sizes larger, and so on; bends must be taken
into account in calculating the flow resistance. See Diagram 1,
Table 1 and the worked example.

Note: An alternative approach for sizing discharge pipes would
be to follow Annex D, section D.2 of BS 6700:2006
Specification for design, installation, testing and maintenance of
services supplying water for domestic use within buildings and
their curtilages.
