Plumbing Jobs You Should Never Attempt Yourself

While there are a few simple plumbing tasks homeowners can handle—like swapping out tap washers or installing a new showerhead—most plumbing work is best left to a licensed professional. In many cases, it’s not just recommended—it’s legally required.

With that in mind, here are some plumbing issues and installations you should always leave to the experts.

Replacing Damaged or Leaking Pipes

If a pipe bursts or starts leaking—whether inside your home or out in the yard—you should contact a plumber immediately. Pipe replacement is not a DIY job.

Even if you feel confident tackling the repair yourself, the risks outweigh the benefits. A mistake could result in serious consequences, especially if it leads to internal flooding and costly water damage.

Plumbing Work During Home Renovations

Home renovations are hugely popular across Australia, and many people enjoy doing parts of the work themselves. However, when it comes to plumbing in kitchens and bathrooms, a licensed plumber is essential.

A professional will need to disconnect existing pipes and fixtures before renovations begin, and later return to install or reroute pipework and fit new fixtures like taps and showers. By law, all plumbing work during renovations must be completed by a qualified plumber.

Installing or Repairing Hot Water Systems

Hot water systems are complex and should never be installed, repaired, or removed by an unqualified person. These systems involve more than just swapping units—they require proper connection to both hot and cold water lines.

If your system stops working, avoid trying to fix it yourself. A licensed plumber can assess whether it can be repaired or if replacement is necessary, and will carry out the work safely.

Toilet Installation or Replacement

Installing or replacing a toilet is another task that should always be handled by a professional. If done incorrectly, it can lead to leaks, blockages, and other unpleasant issues.

While you may be able to replace small components like valves inside the cistern, anything more involved should be left to a licensed plumber.

Clearing Blocked Drains and Toilets

If you’re dealing with a slow or blocked drain, it’s fine to try basic solutions like using a plunger. You can also attempt to clear the blockage with a drain snake if needed.

However, if these methods don’t work, it’s time to call a plumber. Professionals can inspect your pipes using CCTV equipment to locate and remove the blockage effectively.

In some cases, the issue may be caused by a blocked plumbing vent, which restricts airflow and prevents proper drainage. A plumber will be able to diagnose and fix this as well.

Low Water Pressure Issues

If you notice a sudden drop in water pressure, start by checking that your main water valve is fully open. If that’s not the problem, a plumber should investigate further.

Low pressure can be caused by a range of issues, from minor faults to hidden leaks within your plumbing system. A professional will be able to identify the cause and fix it properly.

Dirty or Discoloured Water

Water coming from your taps should always be clean and clear. If it appears cloudy, dirty, or discoloured, there’s likely an underlying issue.

This could be due to a break in a water supply line, allowing debris to enter the system. A licensed plumber can determine the cause and resolve it safely.

Unpleasant Drain Odours

While store-bought drain cleaners and home remedies might mask bad smells temporarily, persistent odours often point to a deeper problem—such as a buildup of waste that could eventually cause a blockage.

A plumber can inspect your system, identify the source of the smell, and provide a long-term solution.
