Stormwater Drainage Fittings: Crucial Products for Proper Stormwater Management

As a vital force that sustains life on Earth, we need rain to support ecosystems, biodiversity, industries, agriculture, food production, as well as human consumption and hygiene. However, experiencing a great deal of rainfall can be too much of a good thing.

Without proper stormwater management, this can easily lead to flooding, which in turn causes damage to buildings with foundational cracks and structural weakening. Risks of damage to the infrastructure, soil erosion, and contamination of groundwater, rivers, lakes, and oceans are also high with uncontrolled rainfall. And then, there are health and safety risks from breeding grounds for bacteria and mosquitoes, too.

Effective drainage is necessary to ensure proper management of the rainfall runoff, the key being the use of quality stormwater drainage products essential for ensuring a smooth flow and, at the same time, preventing leaks. Every component, including the fittings, no matter how small, is crucial for both protecting waterways and reducing pollution.

The Indispensable Stormwater Drainage Products

Our range of stormwater pipe fittings, from connectors like bends, junctions, and adaptors to caps, can meet the diverse needs of industries and developers, while also helping you stay compliant with regulations like AS/NZS 1254:2010 and AS/NZS 2032.

Bend

Available with male and female ends for a snug and leak-proof fit, the plain bends are connector stormwater fittings, also known as simply bends or elbows. Bends are designed to change the direction of a stormwater pipe by 45° or 90°, thus allowing you to change the flow’s direction so it can move smoothly. They can connect pipes both vertically and horizontally in the drainage system.

Junction

What is a stormwater junction? Much like the bend, it is also a connector for pipes. Depending on what you need this connecting piece for, you can choose from the boss and plain junctions.

Seemingly simple, these PVC stormwater fittings are crucial components for creating quick and cost-effective solutions.

These include installing a branch line of pipes into an existing main stormwater drainage line, as in the case of the boss type. All this without the need to cut a full junction into the line, saving both time and money. The plain junctions are ideal for connecting multiple drainage lines into the main one, which is why they’re available in different angles.

Expanda Joint

In areas where soil and building foundations can withstand differential movement, the expansion joints are plumbing joints essential for preventing structural damage to the pipework, all the while ensuring a watertight seal.

Coupling

Reducer

Yet another connecting PVC stormwater pipe fittings product type, the pipe reducer joins pipe sections or tube sections. As an important component, it’s created to assist with changing a pipe size from larger to smaller to connect pipes of different diameters and manage the flow between sections. It’s usually present in connections of roof downpipes to the larger underground pipes.

There’s also the socket reducer, which is similar, with the exception that it’s designed to fit within socketed pipe ends. The stormwater to sewer reducing bush is another reducer that’s also an adaptor, as it connects stormwater pipes of different sizes to the sewer.

Downpipe Drop

Also known as simply downpipes, their function is to provide a way for the water collected by the gutters to go down and away from the building, into the drain. They can connect elevated downpipes with lower stormwater pipes, allowing you to control the gutter water.

Adaptor

A downpipe adaptor is a connector that joins downpipes with standard stormwater drainage pipes, ensuring a secure and leak-free result and optimal drainage system performance.

Cap

Placed on the open end of a pipe, caps are stormwater drainage fittings that serve to seal pipes and protect them from contaminants. They can also be used for sealing certain sections of a system during an inspection, and can also come in handy during a project or for a boost in safety. When it comes to the different types, there are the push-on cap and threaded access cap designs.

The push-on cap makes for quick installation without the need to use any tools. It can easily help you push pipes into place, creating a secure and watertight seal. The threaded access cap is ideal in DWV (Drainage, Waste and Vent) systems, providing access to large access points, perfect for inspection, cleaning, and unclogging of stormwater pipes. As it’s got a threaded design, it makes for easy opening and resealing.

How to Select Adequate Stormwater Drainage Products?

With a range of options, it’s necessary to consider a few aspects to make your selection easier. This includes:

The Layout

The system layout you get depends mainly on the flow of the water, drainage areas and the site’s topography. As there are many components involved, from gutters and grated inlets to swales and underground pipework to collect and discharge the rainwater, you ought to consider all this to ensure you choose the suitable connectors and adaptors. While a change in direction is possible, it’s best not to overdo it out of risk of blockages. This is why mapping out the water flow is so important.

The Pipes

There are different types of pipes used in a drainage system. Before investing in reducers and adaptors, it’s essential to know the types of pipes the system has, the focus being on the size, to avoid using inadequate fittings that are either too big or too small. Both can cause problems such as flow restrictions and pooling.

The Material

As the fittings can go through a lot, from weather elements to soil and water pressure changes, it’s also a must to choose ones made from high quality materials to be sure you’re getting something reliable and durable. UV-stabilised PVC is certainly a go-to choice.

The Regulations

To be on the safe side with local council rules and regulations, it’s best to look for products that are made according to the strict Australian standards and certified to ensure optimal safety, compliance and performance.

Maintenance Musts

To avoid any problems with the system, aside from choosing the ideal stormwater drainage products, a little inspection of the fittings and components can go a long way. Any early sign of water seepage means you can spot the issue and address it in a timely manner without any damage to the system or property. Inspections are also a must before heavy rains.

Additionally, getting in the habit of cleaning gutters to remove leaves and debris can protect the system from contaminants. To further combat stormwater runoff pollution, consider investing in a whole house filter to capture the stormwater and use it for irrigation, toilet flushing, and cooling. The addition of a filter, though, calls for maintenance inspections by professionals every year or two for peace of mind and optimal performance.
