7 Technologies Used by Plumbers to Unblock Drains

Unblocking a drain is a common plumbing service people seek. Blocked drains can lead to slow water drainage, unpleasant odours, and in severe cases, water damage to the surrounding property. All these issues can cause significant disruptions to daily life.

Thus, to address these issues, plumbers utilize a range of technologies. In this article, we explore the top 7 technologies plumbers use to clear blocked drains in Melbourne.

1. CCTV Drain Camera Inspection

CCTV drain camera inspection involves inserting a small camera into the drain to identify the source of the blockage. The camera captures real-time images of the inside of the pipe, which your plumber in Footscray analyses.

This technology is highly effective in identifying the root cause of the blockage, such as tree roots, foreign objects, or structural damage.

2. Hydro Jetting

Hydro jetting is the best solution to clear stubborn clogs. It involves using a high-pressure water jet to blast through stubborn blockages.

The plumber inserts the jet into the drain and delivers a powerful blast of water to dislodge debris and push it through the pipe. Hydro jetting is very effective in removing stubborn blockages when other methods fail.

This equipment is quicker and more effective than a standard drain snake. Further, the water’s force also removes buildup from the pipe walls. As a result, this device not only clears a clogged drain but also reduces the possibility of additional pipe damage or future obstructions.

3. Motorised Drain Snake

You might have used a drain snake many times to clear a clog. A drain snake is a long, flexible tool that enters the drain and dislodges blockages. You can rotate the snake manually to break up the debris and push it through the pipe.

However, plumbers in Footscray use something better than a regular drain snake. They use a motorised one. It works on the same principle as the manual drain snake but they are much more suitable for larger pipes or severe obstructions.

The plumber has additional force thanks to the engine pushing through clogged pipes. The automated feeds on these snakes make it easier to manipulate the cable. When you have an obstructed pipe, the plumber may quickly push the cable through it using a button and easily retract it.

4. Excavation

In some cases, the blockage may be too severe for traditional methods to remove. In these cases, plumbers in Footscray resort to excavation. It involves digging up the affected area and manually removing the blockage.

But you should know this is a more invasive method than any other on this list, however, it is rather effective in removing stubborn blockages.

5. Pipe Relining

Pipe relining involves inserting a liner into the damaged pipe to repair cracks, leaks, and severe blocks. The liner is made of a durable material that can withstand the corrosive effects of water and other chemicals. This method is highly effective in repairing damaged pipes without the need for excavation.

However, unlike using a drain snake or a plunger, only professionals can do pipe relining. So, hire a skilled plumber in Footscray to do it for you.

6. Root Cutting

Another technique plumbers in Footscray use to unblock a drain is root cutting.

Tree roots are a common cause of blocked drains, and removing them can be challenging. Root cutting involves using specialised equipment to cut through the roots and remove them from the pipe. This method is incredibly useful in removing tree roots and preventing future blockages.

7. Cable Cleaning

Cable cleaning is effective for both minor and big plumbing projects. These devices break through blockages by using rotating blades at the end of cables. The blades will also assist in scraping out residue accumulation on the pipes.

Cable cleaners come in a variety of designs, including sectional, continuous, and drum types. Some points to understand about these cleaners:

  • Sectional cable cleaners make use of many cables that can be up to 15 feet long. Since they are safer to operate, these devices are frequently favoured.
  • Compared to continuous machinery, sectional cables move significantly faster and weigh much less.
  • Continuous cable cleaners have only one cable, which can be between 25 and 100 feet long. The machine is heavier and more difficult to move since the full cord is kept inside of it.
  • The continuous machine has the benefit of leaving less of a mess behind than a sectional cable.


In summary, blocked drains can cause significant disruptions to daily life, and it is essential to address them as quickly as possible. Plumbers in Footscray use a range of technologies to unblock drains, including CCTV drain camera inspection, hydro jetting, drain snakes, excavation, pipe relining, root cutting, and chemical drain cleaners.

By utilizing these technologies, plumbers in Footscray can efficiently and effectively remove blockages and restore water flow to the affected area.
