FAQs

Can I use this with round guttering?

No, this downpipe is specifically designed for square and ogee guttering profiles.

Do I need glue for the joints?

No, the push-fit system is designed to be watertight without the need for solvent welding or silicon sealant.

How do I cut the 5.5m pipe to size?

You can use a fine-toothed hand saw. Ensure the cut is clean and square, then use a file or sandpaper to remove any rough burrs.

Is this pipe suitable for commercial buildings?

Yes, its durable construction and high capacity make it suitable for a variety of building types including commercial properties.

What is the primary material?

The pipe is manufactured from high-quality, weather-resistant PVC.

Can I paint this downpipe?

While the black finish is designed for longevity, if you choose to paint it, ensure you use a plastic-compatible primer and paint system.

Troubleshooting

Joint is leaking water

Ensure the pipe is pushed fully into the fitting socket and check that the internal rubber seal is seated correctly and free from debris.

Pipe is bowing or sagging

Add additional downpipe clips at intervals of no more than 1.8 meters to provide better vertical support.

Difficulty inserting pipe into fitting

Apply a small amount of silicone lubricant to the end of the pipe to reduce friction against the rubber seal.

Pros and Cons

Pros

  • Quick and easy installation via push-fit system
  • No chemical bonding agents like solvent weld required
  • High flow capacity suitable for large roof areas
  • Durable, long-lasting PVC construction

Cons

  • 5.5m length can be difficult to transport in smaller vehicles
  • Requires precise measurement before cutting to length
  • Not compatible with round downpipe fittings without adapters

Setup, Compatibility & Care

Installation requires standard cutting tools to trim the 5.5m length to your exact requirement. Ensure the cut edge is deburred to prevent damage to the internal seals of the fittings. When joining, ensure the pipe is inserted fully into the socket to allow for thermal movement. For maintenance, keep the downpipe free of debris such as leaves or moss by installing a leaf guard at the gutter outlet. Periodically wash the exterior with mild soapy water to maintain its appearance. The system is designed to be compatible with standard FloPlast squareline and ogee gutter brackets and accessories.
