We had a gas leak in a pipe buried in plaster, I only detected it because

engineer who sorted it told me that chemicals in the plaster react with
the lead/tin solder. I do believe running gas pipes in plaster is now
discouraged but if it cannot be avoided they should be sleeved.

same applies to copper water pipes.


Presumably why it's been mentioned?
