The FloPlast Deepflow/ Hi-Cap Downpipe Branch is an essential component for homeowners and contractors looking to manage complex roof drainage by merging two downpipes into one. It is specifically engineered to integrate smaller rainwater systems, such as those from porch roofs, into a main roof downpipe drop for efficient water redirection. While it offers a robust and reliable push-fit connection, users should ensure their existing pipework is compatible with the FloPlast 80mm system before installation to avoid leakage or misalignment issues.

No, this specific model is designed for 80mm downpipes and will not provide a secure, watertight fit for 68mm systems.
No, this component features a push-fit system, which is designed to be installed without solvents or glues.
While the material can be painted with suitable outdoor plastic paint, it is generally recommended to use the black component as-is to avoid potential flaking or maintenance requirements.
The seals are integrated into the FloPlast system components. If a seal is damaged, it is best to replace the specific branch component.
No, this product is designed exclusively for external rainwater drainage and is not pressure-rated for internal plumbing or soil and vent applications.
Verify the downpipe is fully inserted past the seal and check that the pipe edge is smooth and free of burrs that may have damaged the rubber gasket.
Apply a small amount of silicone lubricant to the exterior of the pipe end and ensure the pipe is aligned perfectly straight with the branch socket.
Check that you are using the correct 80mm FloPlast pipe; using piping from a different manufacturer may result in improper tolerances and a loose fit.
To install, ensure the downpipe ends are cut square and deburred to prevent damage to the internal seals. Simply push the downpipe into the branch socket until it hits the internal stop. It is recommended to use a silicone-based lubricant on the seal if the pipe is difficult to insert. For long-term care, regularly inspect the joints during seasonal gutter cleaning to ensure no debris has accumulated at the junction. If you need to clean the system, simply pull the branch apart from the downpipes, remove any blockages, and re-seat the joints. Always verify that you are using genuine FloPlast 80mm components, as mixing brands often results in failing seals and leaks.
