Outdoor stopcock leaking

[Juman islam]

Just an update for everyone. My stopcock has been fixed, took around a week in total. Thames Water did all the work themselves and NO water meter was fitted

Hi again all.

After the work was completed. I have noticed very small black deposits coming out from my bath taps and some seen in my toilet bowl. They seem quite dense so just lay sitting at the bottom and the only way to shift them is with a very hard current of water. Any idea what these may be? Attached are a couple of pictures

Probably grit/sediment has got in when the repair has been carried out.

Sometimes the emptying and refilling of a pipe shifts existing debris, even if they haven't let any new debris in.
