trap with double backflow protection
The base unit is suitable for use in drain pipelines made of HT or sewer
pipe DN 100, 125 or 150. When using other pipes such as e. g. clay
pipes or cast-iron pipes, the relevant adapters for HT and sewer pipes
must be used. The base unit is suitable for faecal matter free, typical
household wastewater up to a temperature of 95 °C with pH values ≥ 4
or ≤ 10.

EN 13564
Use in industrial areas or in pipelines, which transport aggressive liquids
is not permitted. This includes cleaning agents, which can damage sanitary equipment, drainage equipment and pipe materials.
2.2.2
Grundfix backflow trap base unit (cleaning pipe) 6 from 11
Place of installation and installation conditions
If the base unit is being used solely as an inlet to a wastewater line
(cleaning pipe), it can be installed anywhere. In the event of a subsequent conversion to a backflow trap for black water (model 4987.419) or
grey water (model 4987.38), the following installation conditions must be
observed.

Product information
Fig. 2: Correct place of installation of the backflow trap
1 - Street = Backflow level
2 - Area safe from backflow
3 - Connection upper floor
4 - Area at risk of backflow
5 - Protection against backflow through backflow trap
The connection of the upper floor (3) onto the underground pipe must
be made between the backflow trap and sewer within the building (5) –
only then is it possible to ensure that the wastewater system can function faultlessly. To ensure that drainage is permanently guaranteed,
backflow traps may not be employed as the central safeguard for a
building with drainage equipment installed above the backflow level (1) –
in the event of backflow, it would lead to flooding in the building due to
wastewater being unable to drain away (4).
