Hello

This may seem like rather daft question but how on earth does one indeed
operate this device?

Similar in appearance to http://www.plumbworld.co.uk/1847-134

I tried to turn the square bit, nothing, then turned the collar thing
underneath the square bit, got a bit of a dribble but not much, after a
few more turns I noticed water emerging from underneath the collar and
in fear of water emerging at considerable speed in directions other than
my original intention and the swift administration of the mother of all
bollockings by the wife I decided it best to turn the collar the other
way and ask first.

I can only assume something needs to be attached to it.

I have looked in the FAQ and googled myself dizzy but seems unable to
find any resources describing the correct operation of this mind
boggling device.
