The FloPlast 68mm Round Downpipe (RP5.5G) is an essential component for professional rainwater management, specifically designed for builders and DIY enthusiasts working on structures of two storeys or higher. Its primary advantage is the extensive 5.5-meter length, which significantly reduces the number of joints required for long runs, creating a cleaner look and a more durable seal. One caveat to keep in mind is that due to its length, transport and handling require careful planning to prevent bending or damage before installation.

Yes, it can be easily cut to size using a fine-toothed handsaw.
No, it uses a push-fit system that relies on internal seals rather than solvent welding.
It can be connected to square gutters provided you use the correct square-to-round downpipe adaptor.
The outside diameter is 68mm.
Yes, the push-fit design allows you to disassemble the downpipe for maintenance or cleaning.
While designed for two storeys, it can be used on single-storey buildings; however, you will need to cut the pipe down significantly.
Ensure the pipe is pushed fully into the fitting and check that the internal rubber seal is not pinched or missing.
Ensure that adequate downpipe clips are installed at intervals no greater than 2 meters to provide necessary support.
Ensure the pipe end is square, deburred, and consider using a small amount of silicone lubricant on the seal.
Installation requires standard PVC cutting tools to trim the pipe to the required length. Ensure that the cut edge is deburred to prevent damage to internal seals. When connecting, push the pipe firmly into the fitting until it hits the internal stop. For thermal expansion, it is recommended to pull the pipe back out of the fitting by approximately 10mm. To maintain the system, periodically check the pipe clips for tightness and flush the system with water annually to ensure no internal obstructions are present. The pipe is fully compatible with all standard 68mm round FloPlast fittings.
