The FloPlast 80mm Round Downpipe is the high-capacity drainage solution designed for large domestic, commercial, and agricultural buildings. With a significantly wider diameter than standard 68mm pipes, the 80mm system is built to clear massive volumes of rainwater rapidly, drastically reducing the risk of blockages and overflows during severe storms. It acts as the perfect companion drop system for FloPlast's heavy-duty guttering profiles, including the 115mm Hi-Cap and 170mm Xtraflo systems. At Gutters.co.uk, we supply the complete 80mm commercial downpipe range, including pipes, bends, branches, and shoes, all ready for fast UK delivery.
Why Choose FloPlast 80mm Round Pipe?
Maximum Water Clearance: The extra-wide 80mm diameter channels a much higher volume of water than standard residential pipes, making it ideal for vast roof surface areas and steep pitches. Fewer Downpipe Drops: Because each pipe handles so much more water, you can safely reduce the total number of downpipes required around large buildings or warehouses. Reduced Blockage Risk: The larger diameter easily clears leaves, moss, and debris that might otherwise clog a standard 68mm pipe. Heavy-Duty Durability: Manufactured from thick, robust uPVC that easily withstands the harsh demands of agricultural and commercial environments without rusting or corroding. Simple Push-Fit Assembly: Despite its industrial size, it uses the exact same user-friendly push-fit system as standard domestic pipes, ensuring a fast and secure installation.
FloPlast 80mm Round Pipe FAQ
Which guttering systems does this downpipe fit? The 80mm round downpipe is specifically designed to be paired with high-capacity guttering systems. It is the designated commercial drop system for the FloPlast 115mm Hi-Cap (Deepflow) and the FloPlast 170mm Xtraflo profiles.
Can I use an 80mm downpipe on a standard house? While you technically can, it is generally considered overkill for a standard 3-bed or 4-bed home. However, if your home has an unusually large roof area, or if you regularly suffer from blocked and overflowing 68mm pipes due to heavy tree cover, upgrading to an 80mm pipe (alongside Hi-Cap guttering) is an excellent preventative upgrade.
How far apart should the downpipe clips be spaced? Because of the sheer weight of the water inside an 80mm pipe during a heavy downpour, correct support is crucial. Downpipe clips should be spaced at a strict maximum of 1.8 metres apart vertically. We also strongly advise securing a clip immediately below the gutter outlet and directly above the shoe at the base.
How do I join two lengths of 80mm downpipe? FloPlast 80mm downpipes come with a plain end and a socketed end. To join them, simply push the plain end of the top pipe into the socket of the pipe below. If you need to join two off-cut plain ends, you will need to use a FloPlast 80mm Pipe Socket.
