The FloPlast Deepflow Hi-Cap Gutter is an ideal choice for homeowners and contractors managing properties with large roof surface areas or regions prone to heavy rainfall. This high-capacity PVC-u system is engineered to handle significant water volume up to 5 litres per second, ensuring effective drainage and protecting building foundations from overflow. While its robust design provides long-term reliability and compliance with industry standards, users should note that as a 3m extrusion, it requires precise measurement and specific joining techniques to maintain a seamless, watertight fit across longer rooflines.

This Deepflow system is designed for compatibility with 68mm round downpipes.
Yes, the PVC-u material is designed for outdoor durability and resistance to UV-related fading.
While it can be used on sheds, it is primarily designed for larger residential roof spans due to its high-capacity nature.
Use a fine-tooth panel saw or hacksaw to ensure a clean, smooth cut that avoids damaging the PVC profile.
The 3m extrusion is supplied as a single length; brackets, unions, and downpipe adapters are purchased separately.
The guarantee typically covers material defects; ensure the system is installed according to the manufacturer's technical specifications for coverage.
Check that the rubber seals are clean and correctly seated within the fittings; ensure the gutter length is properly pushed into the union.
Verify that your gutter brackets are spaced at the manufacturer-recommended intervals (typically 600mm-800mm) to provide adequate structural support.
Installation requires standard PVC guttering tools, including a fine-tooth saw for trimming the 3m lengths and a silicone-based lubricant for rubber seals. Ensure the gutter is mounted at a slight gradient toward the downpipe to encourage flow. The system is strictly compatible with 68mm round downpipes. For maintenance, it is recommended to clear debris and leaves at least twice a year to prevent blockages that could impede the high-capacity drainage performance. Use only water and mild soap for cleaning; avoid abrasive chemicals that might degrade the PVC-u finish.
