Very old stopcock leaking

[JCplumb]

If you're using 2 lead locs so essentially having a lead main going into some copper, then a brass stop tap, then more copper, then back onto lead you will get increased corrosion of the lead after the copper.
Meaning that your tap water will soon start to contain more lead.
If you're not getting the whole lot replaced then at least replace any lead after the conversion to copper.

Oh and the round collar looking bit that bulges out where the spindle enters the valve is the gland nut, you might just be able to service it if you're very lucky.

Thanks for your help JC, sorry for the late reply just got in from work

I have pulled away the ceiling to expose the leak but will have to remove the skirting boards to get a full SP on the problem..meanwhile I have found another lead pipe under the leaking one? someone at work has said that it may be an old gas pipe due to it having a smaller branch pipe coming from it that appears to have been flattened out I will be knocking the damaged wall plaster back to hopefully reveal the end of the pipe

I have a couple of piccies here, do you think it may be gas?

Slightly more expensive and a little more bulky but I much prefer Philmac transition couplings to lead loc fittings when coming off lead pipe. And with the transition coupling you can go on into anything plastic or copper in any size 22mm or 15mm even 28mm. With the lead loc you usually have to go into 15mm then back into 22mm which isn't ideal.
