I'm planning on teeing off these 15mm pipes. The rough line of the pipe is indicated with the loose pipe on top.
My query is the proximity to the joints to the left? The feed is the pipe on top and will be around 65mm away between the old and new joint. Even with a damp rag wrapped, is there a risk of damaging the old joint?
The return I was planning on cutting to right so there's less risk.
