    MDPE Pipes (Medium-Density Polyethylene Pipes) are durable, flexible, and corrosion-resistant pipes commonly used for underground water supply, service connections, and utility distribution systems.

    About MDPE Pipes

    MDPE pipes are designed for transporting potable (drinking) water and suitable for underground installation due to their high resistance to impact and cracking. They offer a lightweight and long-lasting alternative to traditional metal pipework, reducing installation time and maintenance requirements.

    Typically coloured blue for potable water and yellow for gas supply (where permitted), MDPE pipes are used extensively in domestic, commercial, and industrial applications. They are compatible with compression and electrofusion fittings.

    • Underground mains water supply.
    • Service connections to properties.
    • Irrigation and agricultural systems.
    • Industrial and utility infrastructure.
    • Rural and off-grid water distribution.

    Key Features

    • Made from medium-density polyethylene.
    • Typically supplied in coils (25m, 50m, 100m) or straight lengths.
    • Available sizes: commonly 20mm, 25mm, 32mm, 50mm, 63mm, 90mm.
    • Colour-coded (blue for water supply).
    • Compatible with compression, push-fit, and electrofusion fittings.
    • Designed to meet WRAS and BS EN standards.

    Installation & Technical Info

    Install in an appropriate trench with a sand bedding to prevent point damage. Use approved MDPE fittings and ensure connections are clean and debris-free. For water systems, flushing is recommended before commissioning.

    Protect from sunlight when stored for extended periods. Always follow local regulations (e.g. minimum burial depth requirements). Pressure testing should be conducted post-installation.
