The FloPlast Deepflow Hi-Cap Gutter is an essential solution for homeowners and builders seeking to manage high volumes of rainfall in regions prone to extreme weather. Designed with a 115mm width and 75mm depth, it provides a high-capacity flow rate of up to 5 litres per second, making it ideal for larger roof areas. While it offers superior drainage performance and durability, users should note that its specialized dimensions require compatibility with specific 68mm round downpipe systems and careful alignment during installation to maintain optimal flow.

The system can handle a flow rate of up to 5 litres per second.
No, this system is specifically designed for 68mm round downpipes.
It is manufactured in compliance with BS EN 12200 and BS EN 607 standards.
The product comes with a 10-year guarantee.
The Anthracite Grey finish is intended to be durable as-is; painting is not recommended as it may void the warranty and lead to finish degradation.
Yes, the material can be cut using a standard fine-toothed hacksaw, though care should be taken to sand the edges smooth afterwards.
Check that the seals are properly seated and that the gutter sections are fully pushed into the union brackets.
Verify the gutter is properly angled toward the downpipe and check for debris blockages in the downpipe entry.
Ensure that the bracket spacing complies with the recommended distance to provide adequate support for high-capacity flow.
Installation requires standard guttering brackets spaced according to manufacturer guidelines to support the weight of the water. When cutting the 4-metre lengths to fit your specific roof run, ensure that edges are filed smooth to prevent debris snagging and to ensure a perfect seal at joints. This system is designed for use exclusively with 68mm round downpipes; attempting to use non-standard sizes may cause leakage or blockages. To maintain the system, perform a bi-annual inspection to remove leaves, moss, and silt. Use only mild soap and water for cleaning; avoid abrasive brushes or harsh solvents that could damage the Anthracite Grey finish.
