Downpipes might not be the most exciting thing in the world, but you’ll quickly notice if they decide to take a rain check on the job — especially when La Niña comes knocking (again).

Connected to your guttering, downpipes are an integral part of your home's drainage system, keeping your home safe and dry from stormwater.

What are downpipes

Much like the name suggests, downpipes are the pipes that run down the side of a house. They’re connected to the guttering and the stormwater system, channelling the rainwater that runs off the roof. 

This is an important element of your drainage system, preventing rainwater from gathering around the foundation of your house and safeguarding your property from potential water or structural damage.

Downpipes can also be connected to a rainwater tank, which is common in rural and high-fire-risk areas. This lets you collect and store rainwater.

Things to consider when choosing downpipes

Type of downpipes available

Downpipes are available in round, rectangular or square designs and are usually made from some type of steel but are also available in other materials like PVC.

They’re also available in a tonne of different colours so that you can match them to your home’s exterior colour scheme and your existing guttering.

Sizes of downpipes

When it comes to downpipes, capacity is the most important thing to consider as fast and  easy drainage is the name of the game. Ideally, you want your downpipes to effortlessly whisk water away from the roof and the sides of the house as quickly and efficiently as possible. 

If your downpipes are too small, they’ll get blocked or be unable to handle a heavy flow of water. In regions prone to heavy rainfall, opting for a larger downpipe is definitely a smart move. 

Who installs downpipes?

Downpipes are typically installed by roof plumbers or roofers. They can make sure that your downpipes are installed correctly so they can keep your home protected for years to come.

Given how important downpipes are in keeping your house dry and safe, hiring a professional for downpipe installation is definitely recommended. In Australia, it’s often illegal to do any plumbing or drainage works yourself too.

Expertise and efficiency

A qualified downpipe installer will have extensive knowledge of various downpipe materials and styles, including PVC, metal, and composite options. They’ll also be available to answer questions about the size of downpipes required for your region and roof.

Proper fit and functionality

Even the tiniest gap or misalignment can spell disaster for your downpipes. A professional will be able to accurately measure and assess the necessary dimensions for your downpipe system. This precision guarantees that your downpipes will function efficiently and prevent any potential drainage issues in the future.

Prolong the lifespan of your downpipes

Improperly installed downpipes can lead to premature wear and deterioration. A professional installer knows that the hardware and brackets they're using will adequately support the weight of the downpipes, extending their lifespan and reducing the need for frequent replacements.

Safety, reliability and aesthetics

Properly anchored brackets and connectors minimise the risk of accidents or damage, providing you with peace of mind that your downpipes will be doing what they're made for. Given how visible your downpipes are, a professional installation will also make sure they look as good as possible.

Many downpipe installation companies will also offer comprehensive services beyond installation, including:

• Material and style consultation: Assisting you in choosing the right material, size, and style for your downpipes, taking into account factors like weather resistance and personal style and colour schemes

• Gutter cleaning and maintenance: Some companies may offer this as an additional service, helping keep your gutters and downpipes in top working condition and keeping your home safer from floods and fires
• Downpipe repairs: If you're after a repair instead of a replacement, downpipe installation companies should be able to help

How to choose a downpipe installation service

When it comes to choosing a downpipe installer, experience, reviews, and credentials should be at the top of your checklist. Make sure they hold the necessary licenses and insurance to carry out downpipe installation properly. Always ask about any warranties or guarantees they provide, as well as their post-installation cleanup procedures.
