This overview is not complete. To ensure safe and proper usage, read the "installation instructions" and the 
"instructions for use" carefully.

Regulations for backflow stops

NOTICE

 Protection against backflow is provided by wastewater lifting plants with a backflow loop. Backflow stops 

are intended for domestic use and may only be used if permitted by local building regulations and the following 
requirements according to EN 12056-4 are adhered to

 

Gradient from the drainage line into the sewerage system.

 

Flooding does not present a health hazard or threaten valuable property.

 

There are only a small number of users and they have a WC available above the backflow level.

 

Use of the connected drainage points can be suspended in the event of a backflow.

NOTICE

 

Incorrect installation:

  

Incorrect installation may lead to self-flooding and 
backflow if drainage points above the flood level are 
routed to a backflow stop.

Correct installation:

  

Only route drainage points below the flood level to a 
backflow stop. Connect downpipes for surface water 
downstream of the backflow stop in flow direction.
