What are rectangular cast iron downpipes?

Rectangular cast iron downpipes are rainwater pipes with a traditional rectangular profile. They provide the durability and authentic appearance of cast iron while complementing guttering systems designed with rectangular or traditionally detailed downpipes.

Why choose rectangular cast iron downpipes instead of circular?

The choice is primarily based on the architectural appearance and compatibility with the guttering system. Rectangular downpipes can provide a more defined, traditional profile that may better match certain period properties and existing rainwater systems.

Are rectangular cast iron downpipes suitable for period properties?

Yes. Their traditional profile and cast iron construction make them suitable for many period, heritage and restoration projects.

What size rectangular cast iron downpipe do I need?

The required size depends on the roof area and the capacity of the associated guttering system. The downpipe should be correctly sized to manage the expected volume of rainwater.

Can rectangular cast iron downpipes replace existing downpipes?

They may be suitable for replacement projects where the new pipe matches the existing system's dimensions and connections. Existing pipework and outlets should be measured before selecting replacement components.

How do you maintain rectangular cast iron downpipes?

Regularly inspect the pipes, joints and protective coating for signs of damage or corrosion. Keeping the rainwater system clear and maintaining the coating will help support long-term performance.
