Cutting the gutter

1 Manufacturers recommend that gutter and rainwater pipes are cut using a
fine-tooth saw or a hacksaw with a 24-teeth/inch blade.
2 Measure and mark the gutter to the required length.
3 Cut the gutter or rainwater pipe carefully using a fine-tooth saw and de-burr
the cut using a file or rasp.

Making the guttering into the fittings
PVCu gutter systems use a snap-fit jointing system. To make a watertight joint,
simply insert the gutter into the fitting up to the expansion mark. Push the
gutter up into the back of the gutter fitting clip. Pull the front of the gutter
down and clip the gutter in with the front gutter fitting clip using the thumb.

Installation of the rainwater pipe

1 Before installing the rainwater pipe, it is advisable to fabricate the swan neck
bend at the top of the pipe where it connects to the running outlet:
l measure the distance between the two 112.5° bends marked ‘L’ on
Figure 8.22
l cut the length of rainwater pipe, de-burr the pipe and, using solvent weld
adhesive, glue the swan neck bend together; this should be left for 5
minutes to set.
2 Install the swan neck onto the outlet and measure the distance to the shoe
at the base of the rainwater pipe (if the pipe is to be fitted directly to the
p Figure 8.22 Making the swan neck drain, measure the distance to the drain connection).
bend 3 Cut the length of pipe required and de-burr. Install the pipe onto the
bottom of the swan neck and, using a level, mark and drill the bottom
rainwater pipe clip, and screw the clip and pipe against the wall using wall
plugs and 50 mm × 10 alloy or stainless steel screws.
