I was called out to this home to install a dual fuel cooker. When I arrived I was shown through to the kitchen. As we passed by the boiler I could smell gas. It is customary to perform a tightness test (checking for leaks) upon arrival at all gas jobs I undertake. After connecting up and performing the test no leakage was apparent. I surmised that the problem had to be on the burner side of the boilers gas valve. The boiler was isolated while I installed the cooker.
As the house had stood empty for some time with the gas meter control valve gas turned on it is just lucky that the pilot flame didn’t jump across the loose nut and set the wiring on fire or worse. All this bother because some one didn’t test their work with leak detector spray or an electronic leak detector.
