3.3.5 Laying and connecting the on-site inlet pipe
IMPORTANT
Before the inlet pipe is connected, the excavations must be filled up to this level,
Chapter 3.3.12 “Backfill excavations”.
Specifications:
■
Pipe nominal width,
Chapter 7.1.1 “Dimensions”.
■
Lay pipes to be frost resistant.
■
The pipe cross-section must not reduce in the direction of flow.
■
Make flexible pipe joints.
■
Lay up to the tank with a gradient of at least 1.5 – 2 %.
■
Reverse gradients, and the formation of siphons or pockets are not allowed.
■
Select material that is resistant to the wastewater (e.g. KML, PP, PE, PVC).
Î
IMPORTANT Mark the insertion depth at the
spigot end of the inlet pipe (if the spigot
end of the pipe is inserted too deeply, then
the installation parts will be damaged).
Î
Use acid-free lubricant to grease the
spigot of the inlet pipe and the sealing
lips of the socket seal.
Î
Slide the spigot end into the socket seal
up to the marked insertion depth.
3.3.6 Laying and connecting the on-site ventilation pipe
IMPORTANT
Before the on-site ventilation pipe is connected, the excavations must be
backfilled up to this level, Chapter 3.3.12 “Backfill excavations”.
Specifications:
■
Pipe nominal size DN 100, OD = 110 mm
■
Lay the vent stack so that it rises continuously. Do not reduce the stack cross-section.
■
The end of the vent stack must be routed to above the roof or, for example, in the
ground, where it does not cause any odour nuisance.
■
Choose resistant material (e.g. KML, PP, PE, PVC).
