Looking for a Local Plumber in Sydney?
A sewer blockage could be caused by any number of things obstructing the flow of sewerage from the property. It's important to work out what it is so you can have your sewer drains cleared out and returned to working order.
Sewer blockages are the property owner's responsibility to take care of. If a blockage is in the sewer main (normally outside the property boundary), it is the responsibility of your local council or water authority.
In this article, we'll go over what you can expect from a blocked drain, how to identify one, and what to do in the event your sewer system or sewer pipes become blocked.

The most common causes of sewer blockages include:
A build-up of fat, oil and grease
Fat, oils and grease can all solidify when they cool down. Many homeowners dispose of cooking fats in the sink, which is fine until it's time to wash up. The water mixes with the fragments of food still stuck to your plates or utensils, and without proper care can cause massive blockages.
Tree roots
As trees grow, their roots can find a way up the drains and cause blockages. This usually happens when the roots break into the pipes, allowing dirt and debris to make their way in and catching waste as it comes through, forming a blockage.
Food debris
Food that hasn't been washed off before going into the drains can block them too. Food scraps or other types of food debris from cooking or dining can end up clogging the drain if they're big enough. Thankfully most sinks have some kind of filter these days, so the risk is low.
Disposable wipes and other foreign objects
While they might be called disposable, you really shouldn't be flushing wet wipes down the drain. Disposable wipes don't break down well, instead getting caught in your drains and forming blockages over time. This effect is amplified if you're flushing other things as well, such as rubbish.
