Wavin AS+ Technical Manual
A bypass pipe should be used for downpipe offsets
< 2 m.
The bypass pipe should be connected at least 2 m
above the inlet bend and 1 m below it. The bypass
pipe should measure no more than DN 100 (prefe-
rably less), in accordance with the dimensions of
the downpipe.
The 250 mm coupler can be omitted if a bypass
pipe is installed.
