. .. . Doctor Nick, please advise
For some while my wife has been saying "I can smell gas" in the vicinity of the water boiler. I have of course Poo Poohed this. Today the gas service man turns up (this not being Cyprus) and he says"nah, can't smell gas". But being a proper qualified gas man (this not being Cyprus) he gets out his calibrated Gas Sniffomatic (no, not a dog) which starts making clicking noises. Seems she was right all along and a gas valve had to be replaced.
How do I live this down?
