The problem is one of force to turn it on and off and the weak metal most
keys are made from. Far better to construct a protection device around a
normal tap I think.

My local hall has an outside tap. To avoid massive water bills through
the local miscreants turning it and leaving it running all night/weekend
we have taken to turning off a valve inside the building. This year we
have planted a collection of wildflowers and others which until they are
established need watering.
The cleaning lady is happy to do the watering but she isn't very tall and
can't reach the inside shut off valve.

Just to ask the bleeding obvious, the inside valve can't be moved/ add a
second valve lower down/ buy her a step stool?


I'm thinking if the outside tap was operated by a key (Yale type) it
would simplify the task. The only key operated valves Google seems to be
able to find are simple, square/triangle lockshield types.

I expect a triangular tap head will defeat the local yoofs. Given that the
downside risk is say £10 worth of water, is it worth doing anything more
complicated until you've tried that?



Does anyone know if what I'm seeking is available?
