Quick Coupling Valves have an internal valve that is normally closed so that water does not leak out. To activate the valve, lift up the cap and insert a specialised Key to suit. On the top of the key you can insert a sprinkler or a hose.
A top alternative to having taps with stand pipes around your garden or park. When not in use close the lid and you can drive your lawn mower over the top of them.
