Across the UK, thousands of homes still rely on outdated lead or steel water mains — pipes that may be silently harming your water supply. If you're experiencing poor flow, inconsistent pressure, or you're simply unsure what pipe material lies beneath your property, it's time to consider upgrading to a safer, more modern option: 25mm MDPE (Medium-Density Polyethylene).

What's Wrong with Traditional Pipe Materials?

• Copper (15mm): While durable, copper pipes are narrow and prone to internal scaling over time, significantly reducing flow rate.
• Steel: Steel corrodes and rusts internally, leading to pressure loss and potential water discolouration.
• Lead: Lead pipes are not just outdated — they're dangerous. Prolonged exposure to lead in drinking water can cause lead poisoning, especially in children and vulnerable adults.

Why Choose 25mm MDPE?

Modern MDPE pipes offer a host of advantages:

• Wider Diameter: At 25mm, they allow significantly improved flow rate.
• Corrosion-Free: MDPE resists scaling, rust, and chemical degradation.
• Lead-Free Safety: Completely eliminates the risk of lead contamination.
• Certified: WIAPS approved and compliant with modern water regulations.

Government Grants Available

United Utilities currently offers grants to help homeowners replace lead water mains — making this the ideal time to upgrade without the full financial burden.
