Manifold connector

The multi-waste manifold simplifies waste plumbing by grouping all associated pipework from various sources such as sinks, basins, bidets, urinals and showers to one internal point above the finished floor level. The manifold will permit the connection of three 32/38 mm copper/plastic waste inlets to any new or existing 100 mm diameter pipe stack and three 50 mm copper/plastic waste inlets to a 150 mm diameter pipe stack.

The manifold main body is connected to the stack using standard coupling. On the 100 mm manifold, to achieve a 32 mm waste connection, remove the 38 mm inner rubber ring by using the outer ring (for waste pipe maximum lengths see EN 12056-2). Pipework connecting discharge appliances to a manifold should be designed not to cause self-siphonage.

Fixing instructions

  1. Cut the appropriate groove for 32 mm or 38 mm waste connections (100 mm manifold only), remove the grommet and tear out the centre disk where required.
  2. Apply an appropriate silicone grease (not provided) to the outside of the grommet and re-fit into the manifold ensuring the retaining groove of the grommet is located correctly in the casing.
  3. Lubricate the pipe ends and insert into the grommet with a rotational movement. Pipe ends may be chamfered for ease of insertion.
  4. Any grommet not fitted with a waste pipe must also follow instruction 2 above.
