3" Round Cast Iron Downpipes

3" Round

A 3" round cast downpipe (76mm downpipe) is a popular choice as it's a standard size and can fit existing cast iron guttering systems. The main benefit of this type of guttering is that it's easy to install and replace if necessary.

Our 3" downpipe is available painted in gloss black or transit primed (unpainted) with a grey primer.

The 3" downpipe is one of the most common sizes of rainwater pipes in the UK. It is made from cast iron and comes in a wide range of colours to match your roof or other elements of your home's exterior.

These downpipes are usually placed directly below the eave line or above the soffit line (if you have an overhang), depending on where you want them to direct water away from your home. They usually have small holes drilled into them regularly so rainwater can flow through them easily without becoming blocked with debris or silt.

For effective drainage for your building, when you live in heavy rainfall areas, you can get the 125mm guttering from Cast Iron superstore anywhere in the UK.

Benefits of 3" Downpipes (76mm Round Downpipes)

There are many benefits to this size of the gutter, and it is not just a matter of personal preference. These benefits are:

Better Drainage:

3" downpipe systems can cope with greater volumes of water because they have a larger surface area to catch the water from your roof. The increased size means that guttering can better withstand the force of heavy rain.


Installing a 3" downpipe system is cost-effective in the long term, with cast iron rainwater systems having an exceptional service life. Some cast iron drainage systems have been known to last for more than one hundred years.

Improved Design Flexibility:

A 3" downpipe system is suitable for all roofs and can be used on pitched or flat roofs without any problems whatsoever. This means that you will be able to design your roof in any way you want to without having to worry about whether the downpipe will fit your property or not!

Things to Consider During Installation

When installing 3" downpipes with gutters, there are a few things to consider. The first thing is the size of the pipe that you are going to use. This depends on the size of your roof and the height of your gutter. 

The second thing you need to consider is whether or not you want to use cast iron, uPVC, or another metal, like aluminium or steel, for your downpipes. Cast Iron is typically more expensive to install than other materials, but it will last longer because it is stronger and less likely to rust over time.
