Most Common Signs You Could Have a Broken Sewer Line

A broken sewer line is a serious issue. In short, it will allow raw sewage to leak into the surrounding area. In most cases, the leak will be underground, as the sewer line passes under your yard on its way to the main sewer line.

It is important to note that until it reaches the main sewer line it is your responsibility. That means you are going to have to pay the cost of uncovering it and repairing or replacing it.

It is also worth noting that a broken sewer line increases the likelihood of a blockage forming. This means sewage will ultimately have nowhere to go and will come back up the pipes and into your home.

If you think you have a broken sewer pipe you need to contact a reputable plumber Sydney to get the issue sorted.  The sooner the better!

To help, here are the most common signs you have a broken sewer line.


The first thing you are likely to notice is the distinctive aroma of sewage. In short, because it is not enclosed within the pipes the gases can escape and will move through the soil. You’ll notice the aroma in the area that the pipe is broken, even if you can’t see the pipe.

Slow Drains

As mentioned, a broken pipe increases the likelihood of clogs. But, before they completely block your pipe they will slow your drains. If you start to notice that all your sinks and baths are draining slowly you should suspect a sewer pipe issue and you’ll need to have it looked at by a professional.

Lush Grass

Another clear sign that you have a broken sewer pipe is when you have particularly healthy and lush green grass, but only in one area of the garden. This will be on the pathway of the sewer pipe leaving your property. It’s a result of the nutrients in sewage that plants adore.

They are feeding on the sewage and giving you a hint there is an issue.

Increase In Pests

Pests are attracted to any source of food and moisture, it’s what they need to survive. Your broken sewer pipe gives them both and makes your home more attractive to them. If you notice an increase in pests, in or out of your home, then get your sewer pipes checked to ensure there isn’t a breakage.

Mold Growing

A broken sewer pipe means that moisture is leaking into the ground and possibly into your foundations. This will increase the level of damp in your home and effectively create the right environment for mold in your home. Mold is not good for your health.

If you see more than normal then, again, you’ll want to have your sewer pipe checked.

Don’t forget, the longer your sewer pipe leaks the more likely it is that your foundation will be damaged as the moisture will soften the soil, making it possible for part of the foundations to drop and cause cracks in your home.
