The system

A complete socket system for waste, ventilation and rainwater piping inside buildings. Every pipe and fitting has a socket with a lipped rubber ring, so joints are tight as soon as they are pushed home and can be pressure tested straight after installation. No gluing or welding is needed.

The smooth inner wall keeps the risk of clogging low, and the system connects to existing drainage pipes of other materials.

Piping in the building

Collection piping
Horizontal piping in the building, either a main that leads out of the structure and ends 1 m in front of it, or a lateral connected to the main.
Connection piping
Between sanitary fixtures, inlets or other drainage equipment and the stack. The bore follows the kind and number of fixtures, and the pipe runs in wall grooves or under the ceiling.
Stack
The vertical waste pipeline between connection and collection piping, mostly in wall grooves or service ducts. Minimum bore 75 mm for urinals, baths and kitchen sinks in flats, 110 mm for large kitchens.
Stack base
The stack turns into the collection piping through two 45° bends; in buildings of three or more floors a straight 250 mm calming piece sits between them. Reduce the bore only in the vertical part, before the bends.
Branches
Fixtures of different types on one level enter the stack through branches with an inner angle of max. 90°. Identical fixtures can share a double branch; WCs on a double branch need an inner angle of max. 135°.
Cleaning fittings
1 m above the floor, at each change of direction on the bottom floor, on the top floor when the roof gives no access, on every third floor, and on every floor where several fixtures discharge into one stack.
Ventilation piping
The upper section of the stack, rising above the roof, with no fixtures connected. Single fixtures may end in vent caps or valves.

Transport and storage

  • Loose pipes rest on the cargo bed along their full length. Do not drag pipes along the ground or the bed.
  • Take care below 0 °C. Lift with textile belts.
  • Pipes, fittings and seals may be stored in the open for up to two years; after that, protect them from UV radiation.
  • Store pipes and sockets so they cannot deform. Pipes off pallets are stacked no higher than 1.5 m.

Jointing

  1. 01

    Cut with a pipe cutter or a fine-toothed saw in a mitre guide, at a right angle to the pipe axis.

  2. 02

    Clean the cut and bevel it at 15° with a bevel cutter, a fine rasp or a file, to the bevel width b in the table.

  3. 03

    Clean the socket and the spigot end and check the sealing ring.

  4. 04

    Spread the original lubricant evenly on the bevelled spigot. Do not use petroleum-based greases or oils.

  5. 05

    Push the spigot fully into the socket, mark the socket rim on it, then pull the pipe back about 10 mm to allow for expansion. Fitting spigots go fully home.

  6. 06

    Do not glue pipes or fittings.

Anchoring

  • Use steel holders with a rubber lining, sized to the pipe outside diameter. Steel hooks and flexible PVC tapes are not recommended.
  • Fixed holders sit under each pipe socket and on every fitting or group of fittings.
  • Loose holders, with slip sleeves, sit between them and leave the pipe free to expand.

Walls, ceilings and concrete

  • Penetrations and grooves let the pipe run without tension, move as the structure settles and stay protected. No joints inside penetrations.
  • Pipes can be plastered over once wrapped in cardboard, felt, mineral wool or mesh. Insulate hot-water pipes that run alongside.
  • Horizontal connection pipes rest on the brickwork along their whole length, with room to expand.
  • Ceiling penetrations must be watertight and soundproof. Fire-proof sleeves go on the ceiling side with the greater fire risk, never inside the hole.
  • Pipes may be cast into concrete: allow for expansion, fix the line against floating, tape the joints against cement laitance and close the open ends.
13

Fire precautions

  • The system is class B2 to DIN 4102, a material of normal flammability.
  • Collection piping that passes between two fire sectors through a ceiling gets a fire-proof sleeve, whose filling closes the opening at 130 °C.
  • Where collection piping runs through an installation shaft that is a fire sector of its own, every branch gets a fire-proof sleeve.
  • National fire regulations apply in addition.
14

Testing

  1. 01

    Tests cover a technical inspection, water tightness of the collection piping and gas tightness of the collection, connection and ventilation piping. Leave joints visible and accessible until then.

  2. 02

    Water test: openings sealed, clean water, overpressure 3 kPa to 50 kPa for one hour. Passed if leakage stays at or below 0.5 l per hour per 10 m² of inner pipe surface.

  3. 03

    Gas test: a harmless, non-combustible test gas that is foul-smelling or coloured, at 0.4 kPa overpressure. Passed if no gas is smelled or seen in the building after 30 minutes.

  4. 04

    Record the results in writing.
