HANDLING
Brett Martin Soil and Waste Systems are light in weight and therefore
easy to handle. As with all other quality materials, the components
should be handled with due care at all times to avoid damage and preserve
appearance, particularly in low temperatures.
STORAGE
All components should be stored under conditions which will prevent
damage and preserve appearance. Pipes and fittings should be kept in
a cool dry store, with lengths of pipe stacked horizontally on a smooth
level and continuous base to avoid distortion. Extra care should be
taken when stacking socketed pipes so that adjoining sockets do not
exert undue pressure on each other. Stacks should not be more than 1.2m
high to prevent overloading and damage to bottom layers in the stack.
Where pipe and fittings are stored outdoors, cover securely with an
opaque waterproof cover to avoid exposure to the elements.
CUTTING
Pipes can be cut with a hand saw having 6-8 teeth per cm, held at a
shallow angle and sawing with slow steady strokes. A file should be
used to remove any swarf and a chamfer should be made around the full
circumference of the pipe.
PUSH-FIT JOINTING
To ensure watertight jointing the following procedure should be followed:
1. Pipe ends must be cut square. Chamfer the end to about half the wall
thickness and at an angle of about 15º using a file or rasp. Remove
all swarf. Chamfers are moulded on spigot ends of all fittings.
2. Check all seals, sockets on pipes and fittings, and pipe ends, for
a distance equivalent to socket depths, are clean.
3. Apply Brett Martin lubricant around the pipe end or spigot end of
fittings - not around the ring seals.
4. Align components and push the pipe end or fitting spigot fully into
the ring seal socket; mark the pipe or fitting spigot at the socket
face.
5. Withdraw the pipe or spigot until the mark is 10mm away from the
socket face: this creates a thermal movement allowance within the socket.
