Start a replacement job with accurate interface measurements. Match pipes, bends and clips within a compatible range, with outdoor exposure and thermal movement addressed before installation.

1 Match the Interface First

· A nonmetallic body avoids steel rust, but ageing and damage still need inspection.

· Match pipes, bends, connectors and clips by actual system dimensions.

· Measure the old profile, outside size and socket depth separately.

· Allow the specified movement, insertion depth and support arrangement.

3 Location and Accessories

For conventional gravity rainwater drainage, not an automatic substitute for hot water or pressure piping. Review protection near heat sources and traffic, and any fire stopping needed at penetrations.
