Brett Martin 68mm Round PVC Downpipe in Black - 4m
Ideal for carrying rainwater from gutter to gully or drain, this 4m, 68mm diameter downpipe is made from durable, gloss-black PVC. Fully compatible with Brett Martin’s 112mm Roundstyle system, it creates a secure, low-maintenance drainage run for domestic buildings and outbuildings, and is lightweight, robust, and easy to install.
This 4m length of 68mm round downpipe forms the vertical drainage run in Brett Martin’s high-capacity rainwater system. It connects to the running outlet of the 112mm Roundstyle gutter using compatible fittings and directs rainwater to a gully or soakaway at ground level.
Manufactured from durable, gloss-black PVC, the downpipe is lightweight, corrosion-resistant and UV-stabilised to maintain its appearance over time. Fully compatible with Brett Martin’s push-fit accessories including bends, offsets, brackets and shoes, it’s quick to install and supported by a 10-year guarantee.
Perfect for domestic properties, extensions, garages and garden buildings, this pipe forms the backbone of a reliable, low-maintenance rainwater system.

Installation tips
Fit the downpipe to the outlet or offset bend and push into the socket until seated. Then withdraw by at least 5mm to allow for thermal expansion. Use a spirit level to ensure vertical alignment, and mark the wall through the bracket lugs to set fixing points. Drill, plug and secure with corrosion-resistant screws.
If the wall projection requires it, install an offset bend to follow the building contour. At the base of the run, a downpipe shoe should be used to guide water into the drain or gully. Once fitted, water test the system to confirm fall and joint integrity.
Handling
This Brett Martin rainwater system is made from PVC, making it lightweight and easy to handle. All guttering and fittings should be handled with care at all times to avoid not only damage to the product but also preserve the appearance.
Storage
All Brett Martin products should be stored in conditions that will prevent the risk of damage and impact the appearance. Fittings and long items, such as gutter sections and pipes, should be kept in a cool, dry place. Gutter and pipe lengths should also be laid horizontally while in storage on a smooth, level surface to prevent distortion.
If storing gutters, pipes and fittings outdoors, ensure all items remain in their original packaging until installation to protect them and maintain their original appearance.
Maintenance
Regular maintenance of your rainwater gutter systems is essential, with cleaning recommended at least once a year. In areas prone to significant windborne debris, such as falling leaves, more frequent inspections and clearing may be necessary.
The high-gloss finish of the guttering helps resist dirt build-up, but when external cleaning is required, a mild detergent solution is suitable for removing surface grime without damaging the finish.

Customer Collection Notice
Please ensure you have pre-booked your collection slot before travelling to site.
When arriving to collect your order, please report to a member of our Warehouse Team who will register your arrival and locate your goods. Once ready, your items will be picked and brought to your vehicle loading area.
During busy periods, there may be a short wait while our yard team assist other customers or complete other loading tasks. We always do our best to work within your booked collection time.
We respectfully draw your attention to the following important points:
- Loading is ultimately the customer’s responsibility. While our team can assist with mechanical loading using forklifts, we cannot handball items into enclosed vehicles. Customers must ensure their vehicle is suitable and that goods are safely loaded and adequately secured before leaving the premises.
- Sharp sheeting, metal goods, and long/heavy items may pose additional handling risks. Please come prepared with high-quality protective gloves, and any appropriate protection materials to avoid damage to your vehicle or restraints (e.g. ropes or straps). The edges of roofing sheets and metal products can be extremely sharp, and care should be taken when handling.
- We strongly recommend that customers bring their own straps, ropes, or other securing materials, as we are unable to provide these at the point of collection.
- If you are unsure of your vehicle’s load capacity, we can advise the approximate weight of your order in advance. It is your responsibility to ensure your vehicle is suitable for transporting the goods safely and legally.
- Cladco will not be held liable for any damage to your vehicle or goods once they have been loaded and leave our premises. Loading assistance is provided entirely at the customer’s own risk.
