Safe and reliable waste water disposal via a plastic pipe system is an important contribution to environmental protection.
Water is one of the most important foods for humans. Humans can survive for several weeks without solid food, hardly more than a week without water.
Because we get most of our drinking water from groundwater, In addition to economical consumption and responsible use of drinking water, keeping the reservoirs clean is essential to life.
groundwater protection
The disposal and treatment of all waste water from industry- and commercial establishments, but also from private households is regulated in strict ordinances and regulations and is monitored extremely strictly. A breach of such a regulation always entails a considerable fine and can in extreme cases- or repeated cases also have criminal consequences. The supervisory authority can shut down the affected facility or system by ordinance until the damage or defect has been properly remedied. In principle, the polluter has to bear the costs, in private households always the house owner. Is the damage due to improper installation, the use of non-approved materials or even tampering with the system, every insurance company is also exempt from the obligation to provide benefits.
Labelling
The regulations for house drainage are integral parts of the state building regulations. authoritative-
is the DIN 1986 in their latest version. It contains all the criteria for the materials, their processing and laying are stipulated. In Germany, only marked pipes and fittings with the PA approval of the Institut für Bautechnik may be used for waste water pipes, Berlin, be used. In addition to the PA symbol, the identification must also include the nominal diameter and the material (z.B. PP = Polypropylene, flame retardant) emerge.
There are three different types of sewer pipes: KA-Rohr (KAN or KAV) for connection- and connecting lines with low temperatures indoors (color light grey), HT pipe for indoor lines with high waste water temperatures (Color dark grey) and KG pipes for all temperature ranges for laying outdoors (Color reddish brown).

Drainpipes should lead the waste water to the sewage system as quickly as possible. That is why in the DIN 1986 assembly instructions are also included.
HT- and KG pipes
Sewage pipes must be frost-, be heat and chemical resistant. For this purpose, so-called HT pipes are used inside the house, high temperature resistant plastic pipes made of polypropylene, used. you are up 90 °C, short term also until 100 °C, absolutely heat- and shape-retaining. KG pipes are used for laying in the ground (channel-basic-pipe-re) used.
Matched Systems
Most manufacturers now offer complete line systems. All parts can be connected via plug-in sockets, in which seals are already inserted, plug together easily. The tubes can be cut to any required size with a precision saw. A lubricant takes care of that, that the seal is not damaged when plugged together. The individual pipes must have a gradient of 2 to 5 cm/m to the downpipe. If the gradient is too low, dirt particles can remain in the pipe, while the water is draining. Is the gradient too big?, the water shoots over the solid parts, and constipation occurs. A blockage can occur if the pipe cross-section is too small, at the same time, however, there is also a suction effect, which sucks the odor traps empty. To avoid this danger, the nominal diameters of the pipes required for the individual sewage points are prescribed.
downpipe and house connection
The individual drain lines are routed either via a collecting line or directly to the downpipe. This should lead vertically through all floors directly to the house connection. Is this not possible, the pipe has to be "distorted" horizontally up to the house connection and then in a so-called. crash again perpendicular to this. The nominal width of the downpipe must never be smaller than that of the strongest connected supply line, mostly pipes with at least 100 mm nominal diameter used. The downpipe should have a maintenance opening that is accessible at all times at least on every floor. To avoid strong noise development, downpipes are laid in shafts, which are filled with insulation.
