Cast Iron Pipes and Fittings

We offer Hargreaves Foundry's premium Halifax Drain cast iron drainage products, known for their exceptional quality and performance. The Halifax Drain system is a socketless, mechanically jointed solution designed to minimise installation challenges and reduce maintenance costs over its lifetime.

The Halifax Drain and Soil systems are fully compliant with the highest industry standards (BS EN 877:1999 + A1:2006 Incorporating Corrigendum 2008) and have been rigorously tested and certified by BSI Kitemark (Cert No. KM 684754) and BBA (Cert No. 06/4401), guaranteeing exceptional quality and performance.

Key Benefits of Halifax Drain:

  • Exceptional Lifespan: When properly installed, Halifax Drain systems can last well over 100 years, providing a cost-effective and long-lasting drainage solution for your building.
  • Minimal Maintenance: The inherent strength of cast iron and the high-quality epoxy coating create a low-maintenance system, reducing lifecycle costs.
  • Superior Fire Resistance: Cast iron's A1 fire rating ensures exceptional fire resistance, eliminating the need for fire collars and minimising fire risk.
  • Quick and Easy Installation: The innovative jointing techniques of Halifax Drain make installation faster and easier compared to traditional cast iron systems.
  • Adaptable and Sustainable: Halifax Drain system can be easily modified for future building changes, and cast iron is 100% recyclable, making it an eco-friendly option.
  • High-Pressure Couplings: The system's high-pressure couplings are ideal for use in high-rise buildings.
  • Corrosion Resistant: High-quality epoxy coating protects the pipes from corrosion, ensuring a long service life.

Explore Our Range of Sizes and Fittings

Our cast iron drain pipes are available in three standard diameters: 100mm, 150mm, and 200mm, catering to a wide range of drainage requirements. All pipes come in 3-meter lengths for flexibility during installation. We also offer a comprehensive selection of cast iron fittings and accessories to complete your underground drainage project.

Installation and Maintenance

The innovative jointing techniques of the Halifax Drain cast iron drainage system make installation quicker and easier compared to traditional cast iron systems. The uniformity of our cast iron pipes allows them to be cut at any point to accommodate project requirements, while still maintaining a secure seal with the specialised Halifax couplings.

Depth of Pipework and Pipe Falls

For most buildings, Halifax drain pipes can be installed at regular depths without needing extra protection. However, under roads with less than 1.2m of soil cover or in areas with heavy loads, you'll need to consult with a professional to determine the appropriate depth and any necessary protective measures.

The pipework also needs to be installed at a slight angle, called the fall or gradient. This is crucial for the drainage system to function properly. The recommended fall depends on the pipe size and water flow rate. In general, for pipes carrying less than 1 litre per second, a 1 in 40 fall is recommended for 100mm pipes and 1 in 60 for 150mm pipes. There's also a minimum fall requirement to ensure proper drainage - 1 in 80 for 100mm pipes and 1 in 150 for 150mm pipes.

How Long Do Cast Iron Drain Pipes Last?

Cast iron drainage systems are known for their impressive lifespan. With proper installation and care, they can reliably function for well over 100 years. This exceptional durability is due to the inherent strength and corrosion resistance of cast iron itself, which is further enhanced by high-quality protective coatings. These features allow the pipes to withstand harsh weather conditions, exposure to chemicals, and physical impact without degrading or losing their structural integrity.

How to Join Halifax Drain Pipes to Other Systems?

The Halifax Drain system is designed to work flexibly with different pipe materials and sizes as long as the outer diameters match. Our standard couplings allow for easy connections between Halifax Drain pipes and products from other manufacturers.

For example, you can connect a 110mm plastic pipe to our 100mm Halifax cast iron drain pipe (model HD4001) using a dedicated 100mm Halifax Drain Ductile Iron Coupling (model HD4012). This coupling's design ensures a secure and watertight joint, letting you smoothly integrate Halifax Drain into projects with mixed piping materials.
