This 16-metre FloPlast XtraFlo gutter kit in white is designed for properties requiring high-capacity water management, such as commercial buildings, agricultural structures, and large homes. Its key benefit is superior water-carrying capacity combined with UV-stabilised PVC for durability. A potential caveat for some users is that it connects directly to 110mm round downpipes, which may require specific adapters if a different downpipe size is in use.

FAQs
What is the total length of guttering included?
The kit includes a total of 16 metres of 170mm guttering, provided as four 4-metre lengths.
What size downpipe does this kit connect to?
This system is designed to connect directly to 110mm round downpipes.
How do I ensure a watertight seal between gutter sections?
Each joint features rubber seals. For the best results, apply a silicone spray (like SL40) to the seals before pushing the sections together firmly.
What is the benefit of the 170mm profile?
The 170mm profile offers a higher capacity for water flow compared to standard domestic guttering, making it ideal for larger roofs and areas with heavy rainfall.
Is the guttering UV resistant?
Yes, all components are manufactured from UV-stabilised PVC, which helps to prevent degradation and colour fading from prolonged sun exposure.
What warranty is provided with this kit?
The kit comes with a 10-year manufacturer's guarantee from FloPlast.
Can I purchase additional components separately?
Yes, additional FloPlast 170mm XtraFlo system components can be purchased separately to extend the system or replace parts if needed.
Troubleshooting
Gutter system is leaking at joints.
Ensure the rubber seals are correctly seated and clean. Apply SL40 silicone spray to the seals before connecting components for a tighter fit. Check that the gutter lengths are fully inserted into the joints.
Water is not draining effectively.
Verify that the gutter brackets have been installed with an adequate fall (slope) towards the running outlet. Clear any blockages in the gutter or downpipe.
Downpipe connection appears loose.
Confirm that the running outlet is securely attached to the gutter and that the downpipe is properly inserted and secured into the running outlet spigot.
White finish is discoloured.
Ensure that the gutters are not exposed to excessive direct sunlight without adequate ventilation, which can accelerate UV degradation over time. Regular cleaning may help restore appearance. This kit is manufactured with UV-stabilised PVC to minimise this issue.
