I'm not sure that I'll ever have to defend this one to the local authority. They have a problem with enforcement. If they enforce, or relax, a rule in one situation, they must apply the rule equally to every electrician in every similar situation. Now that it's established that nmwu can be pulled into a water line, the worst they can do is make me pull out a pvc and put in a water line instead. I'd love to see that rejection notice!
