Since I did not receive a reply within another thread. I have started one specific to my question.
Can any qualified corgi technician advise me if a gas pipe needs to be sleeved when passed through an internal breeze block wall?
If the answer is YES, can you please advise what is achieved by sleeving the pipe internally?
The reason I ask is that I have two corgi technicians advising with different answers!
Is there an online corgi set of regulations I can refer to?
Thanks for any advice.
