2.3.2 Place of installation and installation conditions
According to applicable regulations, drainage points beneath the back‐
flow level should be secured against backflow from the sewer, see
Ä
‘Regulations from section: Place of installation and installation condi‐
tions’ on page 6 .
A backflow trap can be used if
n
there is a downward slope to the sewer;
n
the rooms are of lower-ranking significance, i.e. neither the inhabi‐
tants' health nor major assets would be damaged in case of flooding
of the rooms;
n
the system is used by a small number of people, and these people
have another WC at their disposal above the back pressure level
which they could use in case of a backflow at the drainage point.
