I tried to dismount a few (difficult to remember it was 5 years ago; 5x cases at worst) 15mm hep2o pipes out of white 15mm elbows using the hep2o dismount tool. With considerable force and stupidity, I pulled the hep2o insert out of the pipe with the insert still inside the elbow despite twisting and pulling the pipe as per instruction. I then stupidly reinserted the same 15mm pipe over the insert which in all cases did require quite a bit of force even with silicone spray and I don't remember any insert being damaged. The question is do I need to redo these sections of pipework (elbow plus 8cm hep2o pipework) as these reinserted inserts may fail? I did use excess pipe clips sometimes using double the recommended amount so the pipework itself is rigid and won't move.
