Blocked sewer or drain? The where, how and why

Is a drain, pipe, shower, toilet or sink blocking up at your home? It’s a common occurrence especially in the older homes of the inner west and eastern suburbs of Sydney.  This and the following posts will cover why this happens and how to handle and prevent blockages. We’ll build your understanding from the ground up with this series!

The series of posts will cover:

  1. The anatomy of your drains and sewer (or put another way, “Where does the waste water go?”)
  2. Where blockages occur and why
  3. How to unblock or repair a problem drain.
  4. In depth look at some of the crucial structures in the sewer and how you can look after them

To start with, let’s look at:

The anatomy of your drains and sewer

As waste water leaves your home, it exits via the drainage system. Rainwater leaves via the stormwater system and water used in the home (waste water) goes into the sewer. This post focuses on the sewer.  All water used in your bathroom, toilet, kitchen and laundry ends up in the same place (unless you recycle your greywater). It all enters the set of pipes that sit underneath your home that delivers the waste to the main sewer system.

Here’s a  diagram of how all the parts of the drainage system work together:

 A blocked sewage can occur at any point or multiple points along this pathway. In Part 2 we will show you how it all works together and explain the reasons why sewers block and how to avoid it

Do you have a question about how the sewer system at your home works?
