We are always told to never take a bath when it's lightning because of the possibility of electrocution if the lightning travels through the metal plumbing. This makes sense. But what if the plumbing connected ot the tub is all plastic? These days we have PEX, CPVC, and other plastic pipes supplying the water to the tub, and PVC drain pipes. Since the tub is not connected to any metal plumbing, is there any danger?
I'm not planning to take a bath or shower during a storm, but I just heard this warning on tv again, and it got me wondering if there's any danger with all plastic pipes. It kind of seems like this may be an outdated warning, if one knows for sure there are no metal pipes connected.
