When DIY Won’t Cut It: When to Call a Plumber

Plumbing issues can start small but quickly turn into expensive disasters if left unchecked. While some minor problems can be fixed with basic tools, others require the expertise of a professional. Knowing when to call a plumber can save you time, money, and frustration.

Below, we’ll discuss the most common situations that call for professional plumbing assistance.

1. Persistent Low Water Pressure

Low water pressure is more than just an annoyance—it’s often a sign of a deeper plumbing issue. If you’ve noticed weak water flow in your kitchen or bathroom taps, there could be several causes, including:

• A hidden leak in your pipes
• Sediment buildup inside the plumbing system
• A faulty pressure regulator
• Corrosion in old pipes

If cleaning the aerator doesn’t solve the issue, it’s time to call plumbers Camberwell. Professionals have the right tools to inspect, diagnose, and repair the problem before it worsens.

2. Slow or Clogged Drains

A slow-draining sink, shower, or bathtub might not seem like a big deal at first. However, if multiple drains in your home are sluggish, it could indicate a more serious blockage in the main sewer line.

Common causes of clogged drains include:

• Grease, hair, and soap buildup
• Tree roots infiltrating underground pipes
• Collapsed or damaged drain pipes

DIY solutions like plungers or drain cleaners may offer temporary relief, but they won’t fix major blockages. A professional plumber can clear out obstructions using specialised tools such as drain snakes or hydro-jetting equipment.

3. No Hot Water

There’s nothing worse than stepping into the shower only to be greeted by icy water. If your hot water system isn’t working, the issue could be due to:

• A malfunctioning thermostat
• Sediment buildup in the tank
• A broken heating element
• A gas or electrical connection problem

While you can try adjusting the thermostat or checking the circuit breaker, hot water system repairs are best left to a professional. Plumbers can safely diagnose and fix issues, ensuring your water heater functions properly.

4. Water Leaks

Even small leaks can waste gallons of water and lead to mold, structural damage, and higher utility bills. Some leaks are obvious, like dripping faucets or water pooling under the sink. Others are hidden inside walls, ceilings, or floors.

Signs of a hidden leak include:

• Unexplained increases in your water bill
• Damp spots on walls or ceilings
• Musty odours in certain areas of the house
• Warped or discoloured flooring

If you suspect a leak, don’t ignore it. A plumber can use leak detection technology to pinpoint the exact location and prevent further damage.

5. Burst Pipes

Burst pipes are one of the most serious plumbing emergencies. Whether caused by freezing temperatures, corrosion, or sudden pressure changes, a broken pipe can flood your home within minutes.

If a pipe bursts, follow these steps immediately:

• Shut off the main water supply to stop the flow.
• Turn on taps to drain excess water from the system.
• Move valuable items away from the affected area.
• Call a plumber as soon as possible.

A professional can quickly repair or replace the damaged section of pipe and ensure your plumbing system is back in working order.

6. Sewer Line Issues

If you notice multiple drains backing up, gurgling noises from toilets, or a foul smell coming from your yard, you may have a sewer line problem. A blocked or damaged sewer line can cause wastewater to back up into your home—a nightmare scenario for any homeowner.

Common causes include:

• Tree roots growing into pipes
• Collapsed or broken sewer lines
• Grease and debris buildup

This is not a DIY fix. Sewer line repairs require specialised equipment and expertise, so call a plumber immediately if you suspect a problem.

7. Running Toilets

A constantly running toilet may not seem like a big deal, but it can waste hundreds of litres of water per day. In most cases, the issue is caused by:

• A faulty flapper valve
• A worn-out fill valve
• Improperly adjusted float levels

While replacing a flapper is a simple fix, persistent issues might indicate a deeper problem within the plumbing system. If your toilet continues to run despite quick repairs, it’s best to call a professional.

8. Strange Noises in the Pipes

Gurgling, banging, or whistling noises coming from your pipes could signal various plumbing issues.

• Banging sounds (water hammer) occur when water flow is suddenly stopped, causing a shockwave in the pipes.
• Gurgling noises may indicate a drain or vent blockage.
• Whistling or screeching can result from high water pressure or a faulty valve.

A professional plumber can identify the cause of the noise and provide the right fix before serious damage occurs.

9. Foul Odours from Drains or Water

If you notice a persistent sewer-like smell coming from your drains, it’s a sign of a plumbing issue.

• A dry P-trap (the curved pipe under sinks) can allow sewer gases to escape. Running water for a few minutes can often fix this.
• A blocked or damaged sewer vent can cause odours to build up in your home.
• A sewer backup may be the culprit if the smell worsens over time.

Don’t ignore strange odours—plumbers can determine the cause and prevent potential health hazards.

10. Problems with Water Quality

If your tap water looks discoloured, has an unusual taste, or smells metallic, it could indicate:

• Rust or corrosion in old pipes
• Contaminants entering your water supply
• A failing water filtration system

Drinking water should always be clean and safe. If you notice any changes, call a plumber to inspect your pipes and filtration system.

11. Plumbing Upgrades and Installations

Aside from emergency repairs, professional plumbers can assist with home improvement projects. Whether you’re upgrading fixtures, installing a new hot water system, or renovating your kitchen or bathroom, hiring a licensed plumber ensures everything is installed correctly and meets building codes.

Some common projects that require professional plumbing include:

• Installing a new dishwasher or washing machine
• Upgrading to water-efficient fixtures
• Moving plumbing lines for a renovation

Attempting these tasks without proper knowledge can lead to costly mistakes. A plumber ensures the work is done safely and efficiently.

When in Doubt, Call a Professional

Not every plumbing issue requires an expert, but knowing when to seek professional help can save you from expensive repairs down the road. If you’re unsure about a plumbing problem, it’s always better to call a plumber rather than risk making things worse.

Professional plumbers provide the experience, tools, and knowledge needed to keep your plumbing system in top shape. Whether it’s a minor repair or a major emergency, a skilled plumber ensures your home stays safe, dry, and functional.
