Petroleum Smell in new Plumbing
A few weeks ago, I had by bathroom enlarged and all new fixtures installed. Since then the water in the bathroom has a very strong petroleum smell. New galvanized pipe was used for the sink and tub/shower that connected to the older galvanized pipe that ran to the room. I am on City water, I did not have any plumbing changes in the kitchen and there is no smell there, just in the bathroom. It is more noticeable in the cold water than the hot.
Several contractors and plumbers are completely stumped by this, saying they have never smelled anything like it and have no idea why the smell has not dissipated after letting the water run several times a day for over 3 weeks now.
Teflon plumbers tape was the only thing used on the threads, no other compounds or chemicals.
Thanks for any help you can give me.
