3)
Using a suitable sized brush, apply a thin, even coat
of solvent cement to the internal surface of the socket
first.
Then apply a thin even coat of solvent cement up to the
witness mark on the spigot, DO NOT USE EXCESS SOLVENT
CEMENT, and DO NOT DILUTE or add anything to
the solvent cement. As a guide the brush should be approximately
one third the pipe diameter and large enough to apply
the solvent cement to the joint in about 30 seconds.
1)
Before jointing, check that the spigot has been cut square
and all burrs removed from the inside and outside pipe edge.
Remove all dirt, and moisture from spigot and socket end.
4)
Make the joint immediately. In one movement insert and twist
the spigot end into the socket so that it rotates to about
a 1/4 turn. The spigot end should be fully homed in the
socket. Hold for a minimum of 30 seconds 
5)With
a clean rag, wipe off any excess solvent cement which
may have built up eternally on the pipe or socket.
