Yeah, almost certainly better to replace than trying to divert or reterminate, it will definately be cheaper to replace it in the long run.

Same with VIR. The problem is that it usually IR tests okay before it's disturbed but as soon as you start working with it or even near it the insulation has degraded so much that it just falls off. I've been caught out in the past so now I don't offer any options with VIR other than replacement.
