Toilet inlet pipe

[StevenHu]

hi
I just noticed there is a "scar" on the inlet pipe of my toilet cistern. I cannot tell if it is just paint missing or some surface metal is worn out. Does anyone know how thick is the metal wall of this kind of pipe and would this defect cause any leaking in future? Thanks.

That's the stop on an end-fed coupler - perfectly normal

Looks like just a chip in the paint, but hard to tell from that photo.
Sometimes pipes get bashed at that level while hoovering etc.
Copper is probably 0.7 to 1 mm thick, I think.

what is a "stop"?

So that the two pipes are inserted into the fitting correctly when they plumbed it in.

Get a clearer picture Steve but I don't think it's anything to worry about.
