Whats the biggest leak you've come across while on the job ? In work today a call came over the radio from the canteen staff there`s a small leak coming through the ceiling. We headed over and traced the leak to the kitchen two floors above... A 28mm compression elbow blown straight off so 28mm full flow with a 6m Jet across the kitchen with no service valve in site, in the 10 minuites it took to get access to the roof to shut off the tank it had flooded every room on all 3 floors, blown all electric and triggered the fire alarm direct to the fire service. All because the nice polish worker unscrewed the basin and left it resting on a wet floor sign which he then kicked over, Hilarious but completely SOAKED
