Septic and Sewer Installations and Repairs - Darwin, Palmerston NT

The most common symptoms of a blocked septic or sewer are:

  • water backing up out of a drain or toilet plumbing

  • gurgling sounds coming from a drain.


In Darwin, problems with septic and sewerage systems generally occur within pipes, which stops sewage from flowing away from your home. 

Sewer and septic blockages damage homes extensively. If left untreated, it can contribute to expensive sewer-line or septic repairs by plumbers.

Some of the most common and often hidden contributors to blocked septics and sewers are:

  • tree roots growing through pipes

  • soil blocking the pipes when plumbing pipes have been split or broken.


If a sewerage or septic plumbing system is blocked, outlets like toilets, showers, laundry and kitchen sinks will not carry wastewater away properly. That can cause serious hygiene and health problems for Darwin households and businesses.


Extreme care must be taken when opening the lids of sewerage systems because poisonous gases can build up in these plumbing pipes.  


If you think a pipe is clogged in your home and you suspect a blocked sewer or septic drain may be the cause, it’s important to shut off the water at the source or at the main. If you’re unsure, call Pett Plumbing and Gas Darwin.
