we have had 2 plumbers around to fix a dripping tap, neither could find the main water cut off.
the tap is now gushing and i have called the last plumber we had in to do work and even he canrt remember where it is.
i have tried every tap i can see and nothing has shut it off.
there is one apparently outside under a grate but needs a special key, both plumbers were reluctant to try.
any ideas what to do next? the amount of water being wasted is a disgrace.
