7 Clear Signs You Need a Professional Plumber for Shower Repairs

03 February, 2025

A hot shower has to be one of the best luxuries in life that we often take for granted. You only realise this when you're so frustrated after stepping into your shower, only to face unexpected issues like a weak water stream.

Whether stubborn clogs or annoying leaks, shower problems can quickly turn a daily ritual into a source of stress, and we all know how important that morning routine is for setting a precedent for the rest of the day.

While some issues may seem minor, ignoring them or attempting DIY fixes can often lead to even bigger headaches later on. That’s where professional plumbing services come in.

Let's dive into 7 clear signs that your shower needs the expertise of a professional plumber. By knowing what to look out for, you’ll be able to tackle issues early, avoid costly damage, and get your shower back in top shape with minimal hassle.

What Makes Up a Shower Plumbing System?

While your shower and hot water system might seem like a straightforward experience, behind every well-running shower, is an existing plumbing system working to deliver water at the right pressure and temperature. You see, your shower relies on several interconnected components to function properly.

Here’s a brief overview of what goes into a shower plumbing system:

  • Water Supply Lines: These pipes bring hot and cold water from your main supply into your shower.
  • Shower Valve: This unsung hero regulates water flow and temperature.
  • Drainage System: After the water does its job, it needs to escape by exiting in a natural downward flow through your shower drain and into the larger drainage system.
  • Showerhead and Fixtures: These components deliver water efficiently and evenly.
  • Waterproofing and Sealants: While not technically plumbing, proper waterproofing and quality sealants around tiles and fixtures are critical in preventing leaks and water damage behind your walls or under your floors.

A problem in any one of these areas can throw your entire shower system off balance. Professional plumbers understand this and know how all these components work together, making them the best choice for diagnosing and repairing issues.

The Importance of Professional Shower Repairs

Opting for professional help for your bathroom plumbing isn’t just a matter of convenience—it’s the smartest choice. While DIY repairs might seem tempting, they often provide only temporary fixes, leaving the root cause of the problem unaddressed (We see this happen all the time when we get called out to fix DIY bathroom plumbing).

Professional expertise matters for many reasons.

Accurate Diagnosis of Underlying Issues

Shower problems can be deceptively complex. A clogged drain might indicate a larger issue within the drainage system, or persistent leaks could stem from hidden pipe damage. We take a leaf out of Toyota's playbook and ask the five whys to get to the root of the issue. Affordable plumbing services prevent recurring issues and save our customers money in the long run.

Access to the Right Tools

Shower repairs require specialised equipment and advanced techniques, neither of which you're likely to possess. And that's okay. We have the tools and the know-how to use them effectively, ensuring the job is done right the first time.

Compliance with Industry Standards

Plumbing repairs must adhere to local building codes and drainage standards. Professional plumbers ensure all repairs meet these regulations, giving you that priceless peace of mind.

Long-Term Cost Savings

While a DIY approach might save money upfront, it can lead to costly mistakes or the need for frequent repairs down the line. Again, we frequently see this happen.

Preventing Further Damage

We've all seen mould growth, that toxic substance on your bathroom roof and/or walls. This is often the result of a once-small shower issue, such as a dripping faucet or slow drain, that's escalated into more serious problems, such as water damage. Get a pro in straight away to prevent plumbing emergencies.

In short, when you invest in professional shower repairs, you’re not just fixing the problem—you’re ensuring the longevity and efficiency of your plumbing system.

When to Call a Professional Plumber for Shower Repairs

Shower issues can sometimes point to deeper problems within your plumbing system that require professional attention. Here are seven clear signs it’s time to call a professional plumber for shower repairs.

Persistent Leaks

A dripping showerhead or water seeping from fixtures might seem harmless at first. But over time, those leaks can lead to extensive damage. Moisture can penetrate walls and floors, causing structural problems and creating the perfect environment for black mould.

Low Water Pressure

If your shower has gone from a cascade to a trickle, it’s a sign of trouble. There could be several issues at hand here. Low water pressure can result from sediment build-up in pipes, corroded plumbing, or even hidden leaks.

Water Temperature Issues

Struggling to find the right water temperature or experiencing sudden changes during your shower? Frustrating, isn't it? Again, this could come down to several issues, from a failing water heater, a malfunctioning mixing valve, or other plumbing problems.

Clogged or Slow-Draining Shower

Standing water in your shower isn’t just unpleasant—it’s a clear sign of a blocked drain. Hair, soap scum, and debris can cause clogs that worsen over time. While DIY methods may offer temporary relief, professional plumbers have specialised tools like drain snakes and hydro-jetting equipment to clear stubborn blockages and restore proper drainage.

Mould or Mildew Growth

If you notice mould or mildew in your shower area, it could be a sign of a hidden plumbing issue, such as leaks or poor drainage. Mould isn’t just unsightly—it poses serious health risks, particularly for those with allergies or respiratory conditions.

Strange Noises from Pipes

Do your pipes bang, whistle, or rattle when you turn on the shower? That's a telltale sign you need a plumber. These noises, often referred to as “water hammer,” can indicate loose fittings, high water pressure, or air in the pipes.

Increased Water Bills

If your water bills have suddenly spiked without a change in usage, a hidden leak could be the suspect. Small leaks, such as those in your shower system, can waste hundreds of litres of water over time, costing you more than you realise.

As such, recognising issues and contacting a professional plumber can save water, costly repairs and water damage.

DIY vs. Professional Shower Repairs

When shower problems arise, you probably wonder if you can handle the issue yourself or if it’s time to call in a pro. While some minor issues potentially can be resolved yourself, it's often best to get an expert.

When DIY Repairs Are an Option

Some minor shower problems can be addressed with basic tools and DIY plumbing. These include:

  • Unclogging a Drain: Try using a plunger or a store-bought drain cleaner. For small clogs caused by hair or soap scum, a drain snake or even a bent wire hanger can often do the trick.
  • Cleaning Showerheads: You may have heard of this trick. If you experience low water pressure caused by mineral build-up, try soaking the showerhead in vinegar overnight.
  • Replacing a Showerhead or Washer: Dripping showerheads or worn-out washers can often be replaced with minimal effort using basic DIY knowledge and tools.

While these small fixes can save you time and money, it’s important to ensure you’re confident in what you’re doing to avoid making the problem worse.

When Professional Help Is Essential

While DIY repairs can be helpful for minor issues, there are certain situations where professional expertise is non-negotiable:

  • Persistent or Widespread Leaks: If the leaks don’t stop after a washer replacement or those hidden behind walls then you require a professional.
  • Major Clogs or Recurring Drainage Issues: If a clog keeps coming back despite your efforts, it could indicate a deeper issue in the drainage system.
  • Low Water Pressure: Persistent low water pressure could be a sign of corroded pipes, hidden leaks, or other serious plumbing issues.
  • Water Temperature Fluctuations: Experiencing hot and cold fluctuations? This likely means the replacement of your mixing valve or water heater—both of which require a pro.
  • Strange Noises or Vibrations: Banging, whistling, or vibrating pipes are never a good sign. It means either high water pressure, air pockets, or loose fittings which can lead to pipe damage if not addressed properly.

The Role of Electrical and Gas Components

It's worth noting that shower systems rely on either electrical or gas components for heating water. As a result, it's important to understand the difference when addressing repairs.

Electrical Shower Systems

Electric-powered systems heat water on demand, using electricity to warm the water in real time as it flows through the pipes. As such, issues with electrical systems—such as inconsistent water temperatures or no hot water—could point to problems with the heating element, wiring, or thermostat.

Gas-Powered Shower Systems

Gas water heaters use natural gas or LPG to heat water stored in a tank or on-demand (instantaneous systems). Common issues include pilot light failures, gas leaks, or faulty valves. Given the safety risks associated with gas systems, professional servicing is highly recommended.

A quality local plumber will have the knowledge and experience to deal with complex issues in both of these systems.
