What Is Hydro Jetting and When Is It Ideal to Use This Plumbing Technique?

Clogged drains are a common plumbing issue typically caused by grease build-up, hair accumulation, and soap scum. Although these nuisances can disrupt your daily routine, they often aren’t difficult to fix. Simple DIY methods, such as using a plunger and flushing the drain with some hot water, are enough to clear minor debris. When dealing with tougher clogs, a drain snake or auger may be used to physically remove the blockage.


However, while these methods can be effective for minor drainage issues, they aren’t the ideal choice for more severe plumbing problems. Large blockages or those deep within the plumbing system almost always can’t be cleared with conventional techniques. If not addressed properly, these drainage issues can lead to persistent slow water flow, foul odours, and even potential pipe damage. In such cases, professional hydro jetting becomes necessary, offering a more powerful and longer-lasting solution to restore proper drainage.

What Is Hydro Jetting?


Hydro jetting is an advanced plumbing technique used to clear stubborn clogs and build-up within pipes. It involves the use of highly pressurised water, which is forced through specialised nozzles to break apart grease, sludge, mineral deposits, and other debris that may be obstructing the drainage system. Unlike traditional methods, such as snaking or chemical cleaners, hydro jetting not only removes blockages but also thoroughly cleans the interior of the pipes, reducing the likelihood of future clogs.

Due to the power and precision required for hydro jetting, this method can only be performed by fully licensed and qualified plumbing professionals. The equipment used operates at extremely high pressures, which, if not handled correctly, could damage pipes or cause injury.

How Do You Know When You Need Hydro Jetting?


Certain plumbing issues indicate that standard clog-removal methods are no longer effective, and recognising them can help prevent costly repairs and potential damage to your plumbing system. However, how do you know if hydro jetting is the right solution for your drainage problem? Here are some key signs that can help you determine when this specialised service is necessary.

Your Drains Run Slow


One of the first signs that your plumbing system may need hydro jetting is slow drainage. If water takes longer than usual to drain from your sink, bathtub, or shower, it could indicate a significant build-up of grease, soap scum, or other debris inside your pipes. While minor clogs can sometimes be cleared with a plunger or drain cleaner, persistent slow drainage suggests that the blockage is more severe and located deeper within the system. Hydro jetting effectively removes these obstructions, restoring normal water flow and preventing further complications.

Your Drainage Pipes Get Clogged Frequently


Occasional clogs are a normal part of plumbing maintenance, but if you find yourself constantly dealing with blocked drains, it may be time for a more comprehensive solution. Frequent clogs indicate that there is an accumulation of debris that simple drain cleaning methods cannot fully remove. In such cases, hydro jetting is ideal because it clears the immediate blockage and also cleans the inner walls of the pipes, preventing future build-ups and ensuring smoother water flow.

Your Plumbing System Backs Up Regularly


If wastewater frequently backs up into your sinks, toilets, or tubs, it’s a serious sign of a major obstruction in your drainage system. If not addressed promptly, sewage backups can pose health risks and cause extensive property damage. Although traditional unclogging methods may help break apart some of the blockage, they only offer temporary relief as they don’t completely remove the material causing the blockage. Hydro jetting provides a long-term solution by thoroughly flushing out accumulated debris, grease, and sludge, ensuring that wastewater flows freely away from your home or business.

Your Pipes are Gurgling or Making Noise


Unusual noises coming from your pipes, such as gurgling or bubbling sounds, can indicate trapped air caused by a blockage in the system. When water struggles to pass through an obstruction, it creates air pockets that result in these noises. This issue often worsens over time, leading to slow drainage or even complete blockages. Hydro jetting can effectively clear out these obstructions, eliminating the trapped air and restoring quiet, efficient drainage.

The Drain in Your Kitchen or Bathroom Smells


Foul odours coming from your drains are a clear indication of trapped debris, grease, or organic matter decomposing within the pipes. Food particles, soap residue, and hair can accumulate over time, creating a breeding ground for bacteria and mould. If regular cleaning does not eliminate the smell, it may be time for hydro jetting. This high-pressure cleaning method removes all built-up waste from your pipes, eliminating odours and improving overall hygiene in your home or business.

When conventional methods fail to resolve drainage issues, hydro jetting offers a powerful and reliable solution. This professional service not only restores proper water flow but also helps prevent or the very least minimise the occurrence of future plumbing problems.
