We're in the Thames Water region. About four years ago we had a water meter installed. It's under a plastic cover in the pavement outside the house. I t has built into it a stopcock which has a hexagonal shaft that takes a "ke y" to turn it on and off. Originally there was a plastic key supplied, whic h was attached to a flexible plastic cord within the small underground cham ber itself. However, within a few weeks someone had nicked that, which sugg ests to me that they are in short supply.
To further support this theory, I can't seem to find anything suitable onli ne. If they were available anywhere, I'd expect this to be the place: http://www.tooled-up.com/subcat/plumbers-keys/183/ However, nothing there. I could use a socket from a socket set, but I don't have any suitably long T piece to attach it to.
Does anyone know where to buy what I'm talking about?
