Offsets and Sealing

Making Up Offsets

When the projection of the fascia is in excess of 455mm the offset is formed with a pipe offcut, and two 112.5° bends (as shown in Fig. 1).

Sealing Pipe Joints

With vertical pipes, joints are usually left unsealed in the sockets so that if any blockages occur the rainwater pipe does not fill up with water to the eaves and create a nuisance.

Only seal joints between gutter outlet and rainwater pipe or offset. (Fig. 2)

Also, any joint which is in the horizontal position such as 90° Branch arms or Bends etc.
