Protect Your Home with Reliable Downpipe Systems

When it comes to safeguarding your home against the elements, one often overlooked yet crucial component is the downpipe system.
These frequently underestimated devices play a crucial role in redirecting rainwater away from the foundation of your home, serving as a front line defense against potential water damage and erosion.
By efficiently channeling water, downpipes contribute significantly to preserving the structural integrity of your home and safeguarding it from the harmful effects of excess moisture. 

What is The Purpose of Downpipes?

A downpipe transfers water from your gutters to the stormwater drain system or into a water tank.

At its core, the primary purpose of a downpipe is to channel rainwater from your roof and gutters into the stormwater drainage system in a home and away from your home’s foundation.
Without an efficient downpipe system, rainwater will spill over the gutters and accumulate around the homes foundation, leading to potential issues such as erosion, flooding, and even structural damage over time.
By carrying the rainwater away, downpipes help protect your home and surrounding land.

Why Install Them?

Installing downpipes on your home is required by law
The roof, guttering and downpipes are all connected and they need to be able to collect and channel rain water from your roofline into the storm water system.
Each area of Australia has slightly different guidelines about gutters and down pipes based upon the regions rainfall.
For example, the rainfall on the Central Coast is very different to central or outback New South Wales towns.

The general rule of thumb though is that no downpipe should collect water from more than 12m of guttering. It’s a little more complex than that though, because you need to consider the roof pitch, the catchment area and the average amount of rain you usually get.
Your roof, gutters and downpipes are all linked in together to ensure there is an effective fall and adequate capacity to discharge all water anticipated during a storm.

Roof Drainage Design

It is the drainage designer’s responsibility to design a rainwater system which allows adequate drainage to occur.
Your roof drainage planning should be done by a professional and typically it is an architect, builder, engineer, or a roofing or guttering contractor who will do the calculations.
The design and installation of a rainwater system needs to comply with the NCC2016 requirements or the Building Code of Australia and Australian Standards AS/NZS 3500.3 Plumbing and Drainage, Stormwater Drainage or AS/NZS 3500.5 Plumbing and Drainage, Housing Installations.

Responsibilities of the Installer

The installer’s must ensure the rainwater system is installed as per the requirements outlined by the rainwater system’s designer.
Adequate fall towards the downpipes must be given to gutters (a minimum of 1 in 500 for eaves gutters and 1 in 200 for internal gutters).
The installer must ensure that the correct number of downpipes of sufficent size are installed, that they are clear of debris and able to discharge correctly.

What Should Be Considered When Choosing Downpipe?

Selecting the right downpipe for your home involves careful consideration of several factors:

In the design and detailing of a roof drainage system, consideration must be given to a range of factors such as:

  • rainfall intensity
  • roof catchment area
  • gutter size/capacity
  • gutter fall
  • gutter outlets (sumps, rain heads, nozzles)
  • downpipe size, quantity and placement
  • overflow consideration
  • material choice
  • Material: Downpipes are commonly made from materials like PVC, metal, or even copper. Each material has its advantages, including durability, cost, and aesthetic appeal. Choose a material that aligns with your preferences and the climate in your area.
  • Size and Shape: The downpipe’s size and shape are critical factors influencing its ability to handle water flow. Assessing the average rainfall in your region is essential to selecting the right size and ensuring optimal performance. Moreover, when deciding on the downpipe’s dimensions, it’s crucial to account for the anticipated volume of water and the potential for debris, such as leaves, entering the gutter system. This consideration ensures that the chosen downpipe not only aligns with the architectural aesthetics of your home but also effectively manages both water and debris flow for a durable and efficient system.
  • Installation and Maintenance: Opt for downpipes that are easy to install and maintain. Some materials may require more frequent inspections or cleaning, so factor in the long-term maintenance when making your decision. Additionally, it’s advisable to explore options that facilitate professional installation, ensuring a seamless setup by experts who can address specific requirements and guarantee the longevity of your downpipe system.
