Can you connect cast iron guttering to plastic?

Connecting cast iron guttering to its plastic alternative is a rare but important subject when it comes to rainwater systems.

Luckily, we have years of invaluable experience supplying and installing cast iron rainwater management systems for customers across the UK, so we know which solutions work and which should be avoided.

For expert guidance on what is best for your home, you’re in the right place.

Below, we explore how cast iron guttering can be connected to plastic and identify the various scenarios in which you may need to consider this option for your property.

Can you connect cast iron to plastic guttering?

Put simply, yes, cast iron guttering can be connected to plastic guttering – with one of the most common solutions being a suitable running outlet and cast iron to the plastic gutter adaptor.

Designed to join two different types of guttering, these adaptors are typically made from durable and lightweight PVC, but it’s worth bearing in mind they are not without disadvantages.

As experts in rainwater management systems, we do not recommend using a cast iron to plastic gutter adaptor. While these handy products can appear to be an affordable and convenient solution, they are often only compatible with systems from the same manufacturer.

That makes finding a cast iron to a plastic gutter adaptor that doesn’t leak and provides a seamless fit, a challenging task.

Not to mention, if the adjoining gutters are set at different heights, it can be impossible to fit a suitable adaptor without having to spend time and effort realigning the guttering.

Why would someone want to connect cast iron to plastic guttering?

While cast iron guttering can be connected to plastic guttering with a helping hand from a cast iron to plastic gutter adaptor, it’s rare that a homeowner will want to combine these materials on their own property.

Often, the only circumstance in which a homeowner will need to use a cast iron to plastic gutter adaptor is if their property shares a downpipe with that of a neighbour.

Homeowners looking for cast iron to plastic gutter adaptors are, therefore, often those with semi-detached or terraced properties searching for ways to join their guttering to next door’s.

Regardless of whether your property has plastic guttering and your neighbour’s has cast iron guttering or vice versa, we strongly believe there are better ways to tackle this issue.

What is the best way to connect cast iron to plastic guttering?

Instead of using a cast iron to plastic gutter adaptor, for example, you may want to consider installing a stopend on both systems and converting them to separate gutters.

While this would require water to be diverted somewhere else, it’s a more reliable and permanent solution than using a cast iron to plastic gutter adaptor. It’s worth noting, however, that this is just one option that may not be suitable for every property.

If you’re not sure which solution is right for you, we always recommend reaching out to professionals for an expert opinion.

At Rainclear Systems, we even offer a free sample service where we send out physical examples to ensure you achieve a like-for-like profile and material match for your rainwater management system; you can do this using our ‘Request a Sample’ button on our product pages.
