5. Installation
and jointing
Wavin has designed its low-noise systems to reduce noise
emissions in concealed and visible installations. However, to
achieve a high level of soundproofing it is strongly recommen-
ded to follow the instructions given below.
Push-fit connections between pipes and fittings must be able
to withstand thermal-related length changes of up to 10 mm
over a maximum length of 3 m. Pipes should therefore be pul-
led out of the coupling by 10 mm once the join is complete.
Push-fit connectors used to join fittings to each other are not
subject to changes in length, and can therefore be pushed
fully home.
5.1. Connecting Wavin AS+ to fittings and pipes
Wavin AS+ connections are fitted as follows:
Check the position and condition of the lip seal in
the coupler channel. You may have to clean the fitting
and lip seal.
Clean the push-fit end of the pipe and/or fitting.
Push the end into the coupling so that it goes in fully.
Slide the pipe (not the fitting) back out of the push-fit
coupling by 10 mm
When positioning pipes vertically, secure the individual leng-
ths with brackets as soon as they have been fitted. This will
prevent them slipping out of place and eliminate the 10 mm
dilatation space.
Fixing
In principle, Wavin AS+ soil and waste water pipe systems
should be installed tension-free and able to withstand chan-
ges in length. The pipes should be secured with sound-absor-
bing brackets that are compatible with the external diameter
of the pipes and completely surround the circumference
of the pipes. We recommend the use of Wavin low noise brac-
kets, designed for securing to the brickwork with screws and
plastic wall plugs. Metal anchors may also be used, although
these do not favour sound insulation.

Cutting pipes to size
Pipes can be cut to size using standard pipe cutters. When
cutting pipes to length, do so at an angle of 90° to their axis.
Remove any burrs or unevenness from the cut ends and rub
down sharp edges.
