    I think it's something other than what you think anyway. When was that piping replaced and when did the scorch marks appear?

    The scorching is likely from a plumber's solder torch, but solder isn't used on compression fittings like you have there. Plus if the scorching was from the piping overheating, then surely the plastic retaining clip and the plastic piping would have melted first, do you think?

    So logically the scorching was there before the current piping.

    I've no idea what to think tbh. Noticed it getting worse over time and thought the clip had weakened through heat and cracked

    the combustion temperature of wood to make it smoulder and char is 230 degrees Celsius the qual plex pipe is only rated to 114 degrees so would burst long before you got to temps required to cause that damage as 10 10 20 said your valves have been replaced and there was soldered joints on copper pipe there before . i would be more concerned that he has used 22mm fittings on 3/4 pipe and instead of changing out the olive has wrapped the olive with ptfe tape

    Additionally, had the copper and brass fittings got up to the temperature required to char wood 1cm away, it would have discoloured from the heat and you'd have oxidation around the copper at least.

    The mistake that was made here was in not placing a heat resistant cloth up against the wall/wood when soldering the original piping before this was ever fitted. Have a look at this short video from around the midpoint.

    Hope it helps!
