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

Replace the tap with a pushdown tap. Then only a set amount can be dispensed and water is still availiable for anyone that needs it.
