A neighbour asked me to clean their conservatory roof after having their main roof retiled. No problem, did it last job yesterday. Came up like New. Used the outside tap to rinse of the few bits left. Turned tap off and it sheared off in my hand. Water coming out full bore, at least eight feet into the garden.
Rang bell, informed customer. No isolation for outside tap, had to turn off at the mains which involved emptying a large cupboard of all items, removing bottom shelf etc.
Called plumber and luckily he could come round within the hour. I charged half price, wished her Merry Christmas and went home.
Might be off the Christmas card list next year but it was a very cheap tap.
