Well, it would be an invalid assumption. The pipes are just pipes. There are no chemicals.

Do you also avoid touching water from your kitchen sink? Your bathroom shower?

You think there's no chemicals in your tap water? You think nothing leaches from your plumbing into the water either?

[throwaway09223]

I think you are probably shower and bathe in water that flows through pipes, so it seems absurd to be concerned about the same water/pipe combination used elsewhere.

If you don't shower or bathe or use modern plumbing infrastructure then please, by all means correct my mistaken assumption.

I believe in normal circumstances its neglegible and not worth worrying about.

This response seems silly. Do you not take shower or baths in tap water? The issue is the same.
