Tree Roots or Grease? The Real Reason Blocked Drains Happen in Craigieburn Homes

The blockage of drains is an example of a household maintenance issue that begins as something relatively harmless but soon grows into a much bigger headache. What starts off with slow drainage from the kitchen sink and even showers can end up causing the drain system to overflow, bad smells, backup of sewerage water, and expensive plumbing repairs. When you ask what causes blocked drains in Craigieburn, the answer may not always be as straightforward as you’d expect.

For one, most people tend to believe that the main cause of the blocked drains is due to the oil or fat poured down the kitchen sink. There are those who also believe that the reason behind the drainage problem is the large gum trees that exist all across the northern suburbs of Melbourne. The truth is that both could be causes for the drainage blockages, although in different ways. Learning about the real causes of blocked drains in Craigieburn would give homeowners some insight into the causes of the problem. Over the last two decades, the suburb of Craigieburn has seen tremendous growth, with the development of new estates among the existing neighbourhoods. So, homeowners should prioritize drain repairs in Craigieburn. 

Why Drains Become Blocked In Craigieburn

A rapidly developing suburb like Craigieburn is one that has well-established streets with mature trees and newly developing estates. Both natural elements and household activities cause drains to become blocked in such a setting.

Several natural elements in Craigieburn cause drains to get blocked:

  • Mature tree roots that are seeking water.
  • Dry weather making the tree roots search for moisture through cracks in the pipes.
  • Old clay pipes in the established properties.
  • Excess grease in the kitchen due to bigger households.
  • Foreign objects being flushed into the toilet.
  • Raining weather that exceeds the capacity of partially blocked stormwater drains.
  • Natural settling of the ground that impacts pipes underground.

Even though it may take just one element to cause a blockage in the drains, there are often many elements combined.

The Major Culprit Of Blockages: Tree Roots

For many plumbers providing Drain Repairs Craigieburn, tree roots are one of the major causes of repeat underground drain blockages. Tree roots seek moisture and nutrients, and even very small cracks in the underground pipe are enough to make the roots get inside. Over time, they create dense root masses capable of trapping:

  • Toilet paper
  • Food waste
  • Hair
  • Soap residue
  • Grease
  • Organic debris

Eventually, the drain becomes completely blocked.

Comparison between Tree Roots and Grease – Which One is the Most Dangerous?

While both problems are considered serious, they cause various issues related to plumbing.

Tree Roots

Generally affect:

  • Subterranean sewer pipes
  • Clay drainpipes
  • Outdoor drainage

Signs may be:

  • Frequent clogs
  • Gurgling toilet
  • Bad odor
  • Overflow from inspection holes
  • Slow draining all around the house

In view of the fact that roots actually damage pipes, repairs may include excavation or trenchless pipe relining together with clearing the blockage.

Grease Clogging

Generally affects:

  • Kitchen sinks
  • Waste water pipes in the house
  • Indoor drainage

Signs are:

  • Slow kitchen draining
  • Odor
  • Standing water
  • Frequent sink clogs

Grease usually does not damage the pipe; therefore, it will clear up with professional cleaning.

Other Common Factors for Blocked Drains in Craigieburn

While tree roots and grease are the two major causes for blocked drains in Craigieburn, there are numerous other factors which can lead to blockages.

Flushable Wet Wipes

Despite being described as flushable, some wet wipes do not decompose in sewage systems fast enough. These wipes tend to get trapped along with grease or tree roots to form clogs.

Build-up of Hair and Soap

Bathrooms often experience accumulation of:

  • Hair
  • Soap
  • Toothpaste
  • Cosmetics

As a result, the flow of water becomes restricted.

Foreign Objects

Toys, sanitary products, paper tissues, cotton swabs, and excess toilet paper are common items found when drains are cleaned out. Unlike toilet paper, many household products are not made to decompose in drain systems.

Collapsed Drainpipes

Aging drain systems sometimes collapse due to:

  • Ground shifts
  • Weight of vehicles
  • Decayed materials
  • Pressure from tree roots

Signs of Warning That Should Not Be Overlooked

Problems with the drainage systems usually do not come suddenly. There is almost always an opportunity to notice certain signs that would indicate a developing blockage before total failure happens.

Pay attention to:

  • Sinks that drain slowly
  • Toilets that bubble
  • Gurgling noises
  • Water rising in the shower
  • Foul odors coming from the drains
  • Overflowing external inspection points
  • Several slow-draining fixtures simultaneously
  • Pooling of water near exterior drains

Early action can help save on much more serious future repairs.

Why Chemical Drain Cleaners Do Not Work

Homeowners tend to rely on drain cleaning products from supermarkets when facing drainage issues. These solutions will help to get rid of grease blocking the drainage and increase the flow of water, but in many cases, this is not the actual problem.

Chemical solutions are unable to:

  • Eliminate tree roots
  • Fix burst pipes
  • Eliminate foreign objects
  • Correct pipe collapse

Using them repeatedly can cause additional damage to old piping or become a risk for professional plumbers later. Diagnosis by specialists is the best way out.

High-Pressure Drain Cleaning: The Modern Way of Treatment

One of the most effective ways to get rid of recurring problems is high-pressure drain cleaning in Craigieburn. In contrast to traditional drain snaking, high-pressure water jetting uses very powerful water jets for scouring the interior walls of the pipes. 

What is being cleared?

  • Tree roots
  • Grease
  • Sludge
  • Soap
  • Sand
  • Organic matter

As the pipe walls get completely cleaned, it happens that the drains stay clean for much longer compared to mechanical cleaning only.

An Example

Once a household in Craigieburn faced regular clogs in the kitchen drain every six months. All previous plumbers used to punch a hole in the grease with a drain auger. High-pressure drain cleaning was eventually applied, and as a result of which all the accumulated grease in the pipe was completely removed, not just a small hole. The improvement in the way the kitchen garbage was disposed of prevented any other problems with clogging for one year after that. It demonstrates how sometimes it is much more important to find out the cause of the problem than to restore the water flow.
