The Wall Tells You Before the Bill Does

Eight signs of a hidden in-wall leak worth checking today.

Have you ever noticed a musty smell or a discoloured patch on your wall and wondered if it might be something more concerning? These could be the first signs of a hidden water leak within your walls.

If ignored, wall water leaks often start small but can lead to major issues like mould growth, rising damp, or even structural damage. That’s why early water leak detection is so important — it can save you from costly repairs and ongoing headaches.

To help, our plumbers in Logan compiled ten practical tips that make identifying water leaks in your walls easier and more effective.

What causes water leaks in walls?

Before diving into the tips, let’s take a moment to understand what causes water leaks. Knowing these common causes will help you identify and address potential issues more effectively.

Damaged plumbing

Pipes with cracks, leaks, or corrosion can cause water to seep into walls. If left unaddressed, this can lead to structural damage and mould growth. For hidden or hard-to-detect leaks, it’s best to call a licensed emergency plumber who can provide fast, accurate leak detection and carry out timely repairs before the problem gets worse.

Worn-out seals

Old or deteriorated seals around plumbing fixtures allow water to track into the wall cavity. This can weaken the surrounding materials and encourage black mould growth. 

Rain seepage

Heavy rain can find its way into walls through small cracks or gaps in the exterior. Over time, this can lead to rot, peeling paint, and internal dampness. 

Poor drainage

Blocked or poorly maintained drains and gutters can cause water to flow into your walls. This can lead to flooding, dampness, and structural damage over time. Proper drainage is important to protect your home’s foundation and prevent costly repairs.

How experts at Adept Plumbing Gas address water leaks

Professional assistance is the safest option for larger or hidden leaks. Ignoring the problem can lead to structural damage or health risks from mould growth.

Common issues like leaky showers or hidden pipe leaks often require expert attention to ensure they are resolved effectively.

1. Testing the damaged area

We begin by examining the specific area where damage is evident. This includes assessing fixtures, fittings, and any visible signs of leakage or structural compromise to identify the source of the issue.

2. Checking behind wall stops

Our team inspects behind the wall stops in shower areas to uncover any hidden leaks or issues contributing to the problem.

3. Conducting a pressure test

To ensure there are no hidden leaks, we perform a pressure test on the plumbing system in the affected area. This helps us detect any weak points or leaks within the system.

4. Shower base flood testing

The shower base is flood tested by plugging the waste with tape or a balloon. This process identifies leaks or drainage issues within the shower base to determine the necessary repairs.

5. Shower screen and wall spray testing

We spray water onto the shower screen and walls to confirm they are watertight and not contributing to any leakage issues.

6. Plumb dinger inspection

As part of our process, we verify the condition of the plumb dinger in baths to ensure it remains serviceable and does not contribute to water leaks.

7. Inspecting in-wall cisterns

If access is available, we open the wall behind the in-wall cistern to inspect for leaks. In cases where water is running off the cistern, we install or cut additional snap vents to manage the issue effectively. If rear access is not possible, we remove the toilet pan to inspect the cistern from below. In some cases, installation issues involving offset pan connectors may contribute to hidden leaks, especially in tight or poorly designed bathroom layouts.

8. Back-to-wall pans assessment

We run a blade under the front of the pan to detect any moisture. If water is present beneath the pan, we address the issue to prevent further damage.

9. Using the latest technology: thermal camera and drain dye testing

For areas with wet carpets or hidden leaks, we utilise the FLIR E6 Pro Infrared Camera, leveraging the latest technology to detect heat signatures and pinpoint the source of the leak. If necessary, we use drain dye to confirm the leak’s origin and ensure the area is thoroughly dried and treated during testing.

10. Photo documentation

Throughout the process, we take detailed photographs of the affected areas, including the front of the property, the damage, and the leak source. This documentation is invaluable for insurance purposes and records.

Prevent water leaks, call the experts

To prevent future leaks, ensure regular maintenance of your plumbing and drainage systems. Cleaning gutters, sealing cracks, or scheduling periodic inspections through our plumbing maintenance services can help keep your home in good shape.
