Help with plastic outside stop tap All aspects of plumbing questions and answers, help, tips and information

[speedwing1]

Hi could you please have a look at these pictures of my stop tap.
I am fitting a new kitchen and i need to turn the water of so that a can lift the sink unit over the stopcock in the kitchen. But I need to remove the internal stop cock first.
I have tried turning the plastic key by the water metre but it wont budge.
Any ideas.
Cheers Paul
ps ho do you add pics to a question?

turn the water off from the external stop valve in the street
this will isolate all water to the house and you can carry out the work safely
