Hot Water Services

Rich from Plumbdog Plumbing responds to a customer report of a strong gas smell around their hot water system — something that always needs to be taken seriously.

What initially appears to be a possible gas leak quickly turns into a full diagnostic process involving gas tightness testing, appliance inspection, burner pressure testing, and system commissioning checks.

In this video, Rich walks through the exact process professional gas fitters use to safely diagnose gas appliance faults and confirm whether the issue lies within the pipework or the appliance itself.

In This Video

•Performing a full property gas tightness test using a U-gauge / manometer
•Inspecting the hot water system and checking pilot and burner operation
•Leak testing fittings using soapy water / leak detection spray
•Identifying installation compliance observations and clearances
•Testing burner pressure using a digital manometer
•Testing inlet gas pressure while the appliance is running
•Diagnosing erratic burner pressure caused by a faulty gas control valve
•Replacing the gas control valve and recommissioning the system
•Performing final safety checks and confirming stable operation

The testing revealed that while the gas pipework to the property was completely gas tight, the burner pressure was behaving inconsistently. After confirming that inlet pressure was correct, the fault was traced to a malfunctioning gas control valve regulating gas flow to the burner.

The Result

Gas pipework confirmed leak-free

Faulty gas control valve identified and replaced

Burner pressure restored to the correct 1.0 kPa specification

Hot water system recommissioned and operating safely

Gas smell issue resolved

This video provides a real-world example of professional gas fault finding and shows why systematic testing is critical when diagnosing gas appliance problems.

Josh from Plumbdog is in Morley, helping a homeowner whose hot water system wouldn’t stop running — a classic sign of a hidden leak.

Using acoustic and thermal imaging, Josh quickly pinpointed the issue: a burst hot water pipe beneath the bathroom floor slab.

The Repair

•Detected an under-slab hot water leak with thermal imaging
•Jackhammered tiles and concrete to expose the corroded copper pipe
•Repaired damaged pipework and performed a full pressure test
•Reinsulated and concreting the slab for a clean, professional finish
•Explained how acidic concrete can eat away at copper pipes over time

Even after the repair, Josh found the old pipework had become thin and brittle, recommending a future rerun of the hot water line through the roof to prevent recurring issues.

•The Result

•Burst copper pipe repaired and pressure-tested

•Slab reinstated with proper insulation and concrete

•Clear explanation for the homeowner on future preventative work

•Hidden leak fully resolved with minimal ongoing risk
