Hi All. I am trying to locate the stopcock in my property. After a good few hours searching I think I may have found it - but would like some advice from plumbers / DIY experts. Is what I have found actually a stopcock? Can you take a look at the pictures attached and tell me what you think? I found it tucked away behind some drawers in my kitchen. I suppose that the easiest way of finding out if this is indeed a stopcock would be to turn it and see if it turns off my water. I did try that however - but it's very stiff so thought it might be sensible to get advice from this forum before proceeding further. Thanks for your time.
