Six months ago, Severn Trent (or their contractors) came along and re- piped all the water mains in my road. Unfortunately, I was away at the time, so didn't get to see how everything worked or have a chat with the blokes doing it. I would very much like to change one of the internal stopcocks in the house as I'm doing up the room and it leaks just a tad. I know they will come along on request and turn it off for you, but I'd rather not have to take a day off just to do this job, so I was hoping to deal with it myself (after all, it's not exactly complex/dangerous etc etc to turn a tap off for a bit!). I had a look over the weekend and couldn't see how to get at the shut off in the street. The access is now in a circular plastic plate about 8 inches across with a key hole. Of course, the key hole is full of asphalt from where they re-surfaced as part of the job. Even digging all that out doesn't help a lot as I can't really see what's going on. Does anyone know how these things are opened and, particularly, whether the keys are available anywhere? Everything I've found so far seems to be too small for the job.
Any help much appreciated, as ever.
