A Beginner’s Guide to Home Drainage Systems

A residential drainage system works well and hard to minimise the risk of flooding. It works by safely and efficiently carrying away stormwater to creeks, rivers and in the process, discharges home wastewater into the main sewer line.

Most of the time, home drainage systems work so well, that they go unnoticed.

However, what happens when there’s a problem with your residential drainage system?

What should you do?

Understanding the ins and outs of your residential drainage systems

It’s wise to know a thing or two about your home’s drainage systems.

Why? So, you can identify if something goes wrong or what might lead to a bigger problem down the line.

When designing and building a house, drainage systems must be in accordance with the Plumbing Code of Australia (PCA), to ensure its durability and quality.

What is involved in a residential drainage system?

  • An array of pipe networks that include
  • Home gutters, downpipes and pipelines,
  • Which connects to larger council, shire and city drainage systems.

Residential drainage systems assist greatly in ensuring household wastewater go directly to the sewer. Let’s explore down below what that entails with a Melville Plumber.


Sewer drainage system

A city’s main sewer line is where your household wastewater should, ideally, get directed to. Insufficient disposal could very well and very greatly damage your home and pose serious health risks to yourself and family.

What are the components of a sewer drainage system?

  • Branch drain lines

Out of sight and out of mind, these lines connect your home’s plumbing fixtures to the main drain lines. They’re often hidden in the ceiling, walls and floor.

  • Main drain line

This crucial pipe connects your home’s sewer system to your municipal’s sewer system and found commonly beneath the foundation slab of your home.

  • P-traps and toilet traps

P-traps hold standing water, located beneath sinks and bathtubs, hold standing water and work to prevent sewer gases rising from your sewer system and smelling up your home. Nobody wants that.

  • Washing machine standpipe

The drain tube of your washing machine empties into an exposed standpipe, leading to a branch drain line, into the home’s main drain.

Stormwater drainage systems

Your home’s drainage system should make provisions for stormwater, be it storing rainwater for cleaning, watering, or directing to your city’s main lines.

What is involved in a residential stormwater drainage system?

  • Gutter systems

Which work to divert stormwater away from your home, protecting the home’s foundation, lawn, driveway from flooding.

  • Downpipes

Which take stormwater down, into your own rainwater collection system or the city’s mains.

With winter on the horizon, it’s essential that you know and make sure your home’s plumbing is ready for rain and storms.
