Leak Detection

When Other Plumbers Miss the Problem, We Sniff It Out… (best Perth leak detection)

In his very first on-camera job, new Plumbdog Evan is out in Canning Vale tackling a frustrating roof leak situation that had left the homeowners soaked (and over it).

Several plumbers had come out before — and none of them figured out what was actually causing the issue. Enter Evan. Calm. Clear. Confident. And bang on the money.

🔍 What Evan Found:
1️⃣ Leaking Internal Corner:
Previous plumbers slapped silicone over the old stuff, which never works. Why? Moisture was still present underneath, so the seal never took.

2️⃣ Downpipe Pot Installed Poorly:
It sat too far into the gutter, creating a blockage that guaranteed pooling water — which always means future leaks.

💬 “If you don’t strip it back and dry it out properly, it’ll just keep leaking. Half a job doesn’t cut it — that’s not how we do things at Plumbdog.” – Evan

🛠️ Here’s What Evan Did Right:
• Stripped out the dodgy, old silicone
• Fully dried the internal corner and resealed it properly
• Adjusted the downpipe pot so it sits correctly
• Reassembled the lot with extra fall for better flow
✅ Fixed properly. No bandaids. Just good plumbing.

Darius Follows the Water Trail and Uncovers Hidden Time Bombs in the Roof

You’d think 30ml per minute wouldn’t be a big deal — but give it enough time, and you’ve got a collapsed ceiling, soaked timber flooring, and a very stressed customer.

This job was one for the books. Darius was called out to inspect ongoing water damage with no obvious source. What he found was a classic Perth plumbing nightmare.

🔍 What Darius Found
• Ceiling collapsed with a bucket catching the steady drip
• Water bubbling up through timber flooring around the waste
• Shower above looked fine — but it wasn’t the real culprit
• External plumbing sealed poorly (not the issue, but yikes)
• Dodgy PEX piping up the wall and into the roof

💬 “This was the plumbing equivalent of ‘Where’s Wally’ — but with water.” Classic signs where water leak detection is required. 

🔧 How He Solved It
• Pressure tested the upstairs plumbing
• Found a puddle sitting in the roof space
• Cut and capped two suspicious water feeds
• Then found kinked PEX pipes with no elbows — dangerously installed and likely to fail
• Identified the root issue and recommended future-proofing the rest

✅ Pro tip: Poor installation = guaranteed future disaster. Don’t wait for the pipes to let go!

It’s not uncommon for us to receive a call shortly after a hot water system installation — especially when a customer notices water around the unit. At Plumbdog, we always take those calls seriously and act quickly to investigate.

In this case, James returned to a Perth home where our team had recently installed a heat pump hot water system. The customer had reported:

• Concerns that the system may not have been installed level
• Water pooling around the base of the unit

🔧 Step 1: Inspecting the Hot Water System Installation

The heat pump system was originally quoted by James and installed by Chris, one of our Plumbdog pups, under supervision. On reinspection, James found that:

• The unit was firmly secured and correctly positioned
• It was level and neatly installed
• The installation followed all manufacturer and plumbing code requirements

💬 “It’s important to check the install with fresh eyes — and it’s just as important to reassure the customer when everything looks spot on.”

💧 Step 2: Investigating the Source of the Water

Next, James turned his attention to the reported leak. What initially looked like water escaping from the system turned out to be:

• A below-ground leak from a deteriorated copper pipe
• Located just beside the hot water system, inside the customer’s reticulation box

These types of leaks are often mistaken for an issue with a newly installed system — especially when they show up in the same area.

📞 Communicating with the Customer

James made every effort to explain the findings to the customer, including:

• The difference between the system’s installation and the unrelated underground leak
• Offering a quote for a proper repair of the copper pipe
• Providing clarity around how these things can happen, especially in older homes or with ageing plumbing

While the customer chose not to proceed with the repair through us, our approach stayed the same: assess thoroughly, explain clearly, and offer a solution.

🧠 What You Can Learn from This Job

• Not all water around your system means a faulty install — it could be an existing issue nearby
• Heat pump systems are highly efficient and reliable when installed correctly
• Professional inspections include checking all surrounding plumbing, not just the unit
• Customer presence during install can be helpful, but clear post-install communication is just as important

Modern Concealed Cistern Installed in External Wall — Diagnosed and Repaired

It’s becoming more common to find toilet cisterns hidden away in wall cavities or behind sleek tiled features. They look neat — but when something goes wrong, access can be a nightmare.

Our Plumbdog plumber Darius was called out to a Perth home where the customer reported a leaking toilet. What he found was a concealed cistern hidden behind an external duct panel in the wall cavity.

💬 “These modern setups look clean, but they’re prone to failure — and getting them apart is a bit of a trick.”

🛠 Step-by-Step: How We Fixed the Leak

Here’s how Darius tackled this hidden cistern repair like a pro:

1. Located the cistern inside the external wall cavity behind a duct sheet
2. Removed the cold water feed to stop supply to the cistern
3. Carefully disassembled internal parts, including:
   • The inlet valve
   • The outlet mechanism
4. Assessed space — thankfully, there was just enough room to remove the full cistern
   • If the cutout had been smaller, removal would have been impossible without cutting walls or tiles
5. Identified the need for replacement parts — including specialty air hoses
6. Ordered and installed new parts
7. Reinstalled the cistern, sealed it up, and tested thoroughly at the toilet

✅ Final Result: Leak Fixed, Customer Happy

After reinstalling and pressure testing the new setup, the toilet was back in working order — with no more leak, no damage to the wall, and a very happy homeowner.

👨‍🔧 “These kinds of installs can go sideways if not handled carefully — especially when you don’t have access. Luckily, we’ve been around the block a few times with these.”

🧱 Why Hidden Toilet Cisterns Can Be a Problem

While concealed cisterns offer a modern look, they come with risks:

• Poor access makes repairs time-consuming
• Air hoses and internal fittings are often fragile and fail over time
• Tile or wall removal may be needed if the original builder didn’t allow room for servicing

At Plumbdog, we have a nose for leak detection and we’re equipped to handle these trickier repairs without the drama.
