Junctions in a drainage system are used to connect two pipe runs together. They are available in 45 degrees (often called Y Junctions).
When using junctions in a drainage installation it is important to remember the basic principle of drainage design that all parts of the system must be accessible for inspection and cleaning.
110MM UNDERGROUND DRAINAGE
In terms of installation and connecting pipes to fittings, the process is the same as with 110mm pipes. Cut pipes should always be chamfered prior to insertion into a fitting, and seals should be lubricated with silicon spray or grease.
110mm drainage is often still referred to as, reflecting the old comparative imperial size that was used. As this old pipe was commonly made from clay or salt glaze, flexible rubber adaptors are now available to make a straightforward connection from this old material to PVC.
