Designed to efficiently collect and divert excess groundwater, the perforated pipe ensures effective drainage for your land. The included geotextile filter sleeve acts as a protective barrier, fitting over the pipe to prevent sand, silt, and debris from entering and clogging the perforations. This setup keeps your drainage system clear and functional, improving the permeability of the surrounding backfill. It serves as a practical, cost-effective alternative to traditional, expensive filter materials and is designed for easy installation by a single person.

FAQs
What is the diameter of the pipe?
The pipe has an outer diameter of 100mm.
Does the sleeve come pre-installed?
Yes, the kit includes a matching filter sleeve designed to fit over the 25m coil of pipe.
Can I install this alone?
Yes, the kit is designed for easy installation and is lightweight enough for one person to handle.
What type of backfill should I use?
It is recommended to use clean, washed gravel or aggregate to allow for maximum water permeability and to protect the filter sleeve.
How deep should I bury the pipe?
Typical depths range from 400mm to 600mm depending on your specific soil conditions and drainage goals.
What is the purpose of the filter sleeve?
The sleeve acts as a barrier to prevent silt, sand, and fine debris from clogging the perforations in the pipe.
Troubleshooting
Water is not flowing from the outlet
Check the outlet for blockages or ensure the trench slope is sufficient to allow gravity to move water toward the discharge point.
Silt build-up at the discharge end
Verify that the backfill material used is clean, washed aggregate; fine sand or soil in the backfill can overwhelm the filter sleeve.
Pros and Cons
Pros
Integrated filter sleeve reduces maintenance by preventing silt clogs
Flexible pipe allows for easy routing around garden features
Lightweight construction facilitates one-person handling
Complete kit provides everything needed for a standard installation
Highly efficient for diverting excess surface or groundwater
Cons
Requires proper trench excavation and backfill selection for optimal performance
Not suitable for high-pressure industrial flow applications
Filter sleeve may require care during backfilling to avoid tearing
Setup, Compatibility & Care
Excavation: Dig a trench of appropriate depth for your drainage requirements, ensuring a consistent slope.
Preparation: Uncoil the 25m pipe and ensure the pre-fitted filter sleeve is secure and intact.
Placement: Lay the pipe into the trench. Ensure the perforations are clear and the pipe is not kinked.
Backfilling: Surround the pipe with permeable material such as clean gravel or aggregate. Avoid using heavy, clay-rich soil directly against the filter sleeve.
Maintenance: Regularly clear surface drains or outlets to ensure the pipe can discharge water freely. Periodic inspection of the outlet point will confirm the system is moving water as intended.
