Minimising the likelihood and cost of blocked drains


Blocked drains are both inconvenient and unpleasant. There are, however, a few things to keep in mind that will help detect a blocked drain early, and steps that can be taken to minimise the likelihood of blockages altogether.

If you do have a blocked drain, Pav Plumbing can definitely help fix the problem. We can clear the blockage using a high pressure water jetter or electric eel (also known as a plumbers snake), and for reoccurring blockages we can use a CCTV drain camera to locate the cause and location of the underlying problem. Whether you have a blocked toilet, basin, shower waste or drain grate, or you have a sewer or stormwater blockage, our Sydney plumbers are experienced and can quickly unblock any blocked drain.

Detecting blocked drains

Is your drain blocked? Early detection of a blocked drain can drastically reduce the work involved for a plumber to unblock and clear it, saving you money. Tell-tale warning signs to look and listen for include:

  • A gurgling or gulping sound (often accompanied by a smelly drain grate) coming from the floor waste or toilet when water is in use;
  • The water level in the toilet rising above or falling below normal levels, and/or the drain outside the house overflowing, especially after the washing machine has been in use; and
  • The floor waste overflowing during a shower.

If you do suspect that you have a partially blocked drain it is best to call in a plumber to clear it as soon as possible.

Preventing blocked drains

Tree roots are the most common cause of blocked drains in Australia. Especially in the hottest months of summer, trees will be thirsty for water and will be drawn to the condensation that forms on the outside of pipes. These roots will eventually break through and gradually cause a stormwater or sewer blockage. When clearing a blocked drain we try to identify which trees are most likely to be causing the problem. As a general rule trees and plants should be planted as far away as possible from sewer and stormwater drainage lines.

Visit Sydney Water for more information on how tree roots can block drains and cause sewer overflows. Sydney Water also publishes a list of known problem tree species on their website and it is worth referring to this if you are about to plant trees.

It is also important to be careful what you put down your sinks. Fat and grease will stick to the inside of drains and should never be disposed of down the sink. Large amounts of hair can cause clogged or blocked drains and should be prevented from going down your shower waste or vanity basin. Excessive loo paper is a common cause of a blocked toilet. Cement or plaster from DIY repairs will also prevent water flowing smoothly through your sewer and may cause a blocked drain.
