Plumbing problems always strike at the worst possible time

Summer weather in Sydney has been predictably unpredictable. In the aftermath (or is it still happening?), we continue to see the knock-on effect of these extreme weather conditions (specifical rain) on Sydney’s drains. Unfortunately, hoping that these problems will go away, especially in March – Sydney’s 2nd wettest month on average can cause homeowners a whole host of new, more costly issues. 

As we know (and if you don’t, check out ‘what is the root of the problem’) many defects, specifically in sewer drainage, are caused by tree roots. The main two ingredients of a tree’s diet (photosynthesis) are sunlight and water, both of which we have had in abundance over the past three months. 

What this means is that any existing cracks caused, or intrusions made by tree roots are likely to have worsened, and if you haven’t already, you and your plumbing are more likely than ever to fall out as the heavy rain not only feeds the trees but brings a few other notable issues.

Increased Pressure 

Heavy rainfall, the type we have been experiencing the last few weeks, can saturate the ground causing sand and dirt around your pipes (often buried beneath your driveway or garden) to turn to mud. Mud, due to the increased water content is heavier and in turn, applies more pressure to the piping. In isolation may not be an issue for newer, durable systems, but if you have pre-existing problems, the chances are they are going to rear their ugly heads in the foreseeable future. 

Shifting Pipes

The increase and decrease of ground pressure can lead to the shifting of pipes underground. Older terracotta pipes are particularly susceptible to shifting and can often crack or rupture following high rainfall, usually leaving behind a mess buried deep underground. 


If pipes have existing leaks, heavy rain can allow debris to enter the pipes causing blockages which can cause many issues. Whilst we focus primarily on relining broken pipes, they still need to be unlocked before they can be relined correctly.

Tree roots remain drain’s & pipes’ mortal enemy, but their sidekick, the rain, only strengthens their power. Whilst there may not be a perfect time to reline, as the weather continues to test us and a wet winter just around the corner, now might just be just about as good as it gets. Much better to wrap up warm inside with the knowledge that your newly relined pipes are safe from the trees than peering out the window and waiting for the worst to happen!
