Question from Angelique
A plumber was just telling us about a polyethylene coating for outgoing pipes. It’s installed by placing air-filled bags into the pipes. The coating is on the outside of the bags. It sticks to the pipe walls and dries, sealing leaks. I’m not sure how any VOCs from the wet material could get back into the house (especially if you blocked your drains) but I thought I would see if anyone has heard of this product or has had experience with it.

I don’t see how polyethylene would emit toxic vapors in this use, as it doesn’t in other uses.
