Damn !!! .... Had a very slow leak in an underground cold water pipe that I had been trying to find for the past couple of months. I finally relented to 'the Missus' and called in a plumber who specialises in just such a problem. He and his apprentice arrived 8 days late, (typical Cairns tradesman). Anyway, upon his arrival, he informs me that this exercise will not come cheaply, and that I should expect a hefty bill for his specialised equipment and technical expertise. O.K., he's got me on the spot now. I say, " how much to find and fix the 'tiny' leak ? He says "how long is a piece of string"?. He connects his compressor up to the garden hose tap, fills the lines with compressed air, then dons a big pair of earphones connected to a high powered amplifier and microphone, which he held close to the ground.
He walked 10 paces along from the water main, and said "bingo", dig here kid". The entire job took a grand total of 20 minutes from arrival to departure, parts, about $10.00, ......... my bill, .......... $498.00. DAMN & DOUBLE DAMN, ....... that *&%)^%^$@ makes locksmiths fees and charges seem like chicken feed. He said he does around 5-8 jobs a day, and is so busy he has had to put on and train and equip another couple of tradesmen. To be honest, I would not be able to sleep at night charging ordinary folks that kind of money for 20 minutes work, specialised gear / training or not. His gear would not be any more expensive than our code machines, and the skill level to use his leak detector set up would be pretty minimal, just have to listen for an underground whistle, dig down 2ft and fix the sucker. To say I'm pi*sed off would be an understatement.
