Installation is as for Classical fixed socketed pipe, the loose socket, however, is loosely inserted into the pipe before establishing fixed centres.
The socket will perform without the need for filling in the vertical position, but if preferred a suitable low modulus sealant or filler can be used.
To establish pipe length required, loosely insert socket and follow Step 6 in Fixed Socket Section.
Note: Allowances for socket depths, refer Dimension A. (Fig. 1)
Note: When cutting pipe to length, ensure cut ends are clean and square to give a neat appearance. Any gaps can be filled using a proprietary mastic filler for external use.
In a situation where the connection at the base of the rainwater stack runs into the drain inlet, a galvanised steel wall fixing bracket or eared access pipe (100mm only) will be required to retain pipe barrel. (Fig. 2)

This is the reverse procedure to the previous section. The first pipe to be fixed is positioned and marked relative to the offset/gutter nozzle. (Fig. 3)
The process is repeated up to the last full pipe length.
The pipe at the base of the stack will have to be cut to length relative to the shoe.
The loose socket is located and fixed so that it fully supports the offset, or is located beneath the nozzle.
A pipe barrel is then inserted into the inlet of the loose socket.
Both pipe and socket are then offered to the fixed socket spigot ensuring that the pipe end is Iocated to the underside of the fixed socket.
Holes on the loose socket are marked, drilled and socket is then fixed.
This is repeated until stack is completed.
