Extended Product Information

FAQs

Can this pipe be used for driveway drainage?

This pipe is primarily for sub-surface land drainage. If used under a driveway, it must be buried deep enough to avoid crushing from vehicular traffic.

Does the 50m coil include everything needed to join it?

The product includes a coupling for connection; however, you may need additional connectors if you are cutting the pipe into multiple sections.

Is this pipe resistant to roots?

While durable, no perforated pipe is fully immune to aggressive root systems. Ensure trees or large shrubs are planted a safe distance from the drainage run.

What is the primary benefit of the 80mm diameter?

The 80mm size offers an excellent balance between high flow capacity for groundwater collection and ease of installation in standard residential trenches.

What is the purpose of the perforations?

The perforations allow surrounding groundwater to enter the pipe so it can be transported away from the saturated area to a safe outlet point.

Troubleshooting

Pipe seems to flatten when uncoiling

Ensure the pipe is not kinked. Allow it to warm up in the sun, which makes the plastic more pliable and easier to straighten.

Water is not draining away as expected

Check the gradient of your trench to ensure it has a consistent downward slope and verify that the outlet point is not obstructed.

Joints feel loose or disconnected

Ensure the provided coupling is seated firmly and that no dirt has entered the connection point during installation.

Pros and Cons

Pros

  • Meets rigorous BS4962 safety and performance standards
  • Generous 50m length minimizes joint requirements
  • Easy to handle and transport due to its coiled design
  • Includes necessary coupling for immediate installation
  • High-durability material suitable for long-term burial

Cons

  • Requires proper trench preparation to avoid silt blockage
  • Coil may have a 'memory' effect making it stiff during cold weather
  • Not intended for high-pressure or pressurized fluid applications

Setup, Compatibility & Care

To ensure peak performance, follow these guidelines for setup and care:

  1. Trenching: Dig a trench deep enough to slope at a gradient of at least 1:100 to encourage gravity-fed water flow.
  2. Backfilling: Always surround the pipe with a layer of clean gravel or shingle before backfilling with topsoil to prevent blockage.
  3. Geotextile Wrapping: For areas with fine, sandy soil, consider wrapping the pipe in a geotextile membrane to provide an extra layer of filtration against silt.
  4. Handling: If the pipe is stiff due to cold temperatures, store it in a warmer area before uncoiling to make it easier to manage.
  5. Maintenance: Periodically check your system's discharge point to ensure the outlet is not clogged by debris or plant growth.
