Plumber for horrible shower smell
Hi friends - looking for a GOOD plumber with some problem solving skills. We’ve had a shower that smells like sewage/sulfur after we use it. It was redone in 2021 and was fine for a few years, but for the last 12-18 months it smells awful for an hour after use. Then the smell goes away. We’ve had two plumbers out to do what I assume is some level one troubleshooting (checking other sinks nearby, cleaning soap scum up, cleaning out the drain, etc.) but nothing has worked.
Does anyone have experience with a plumber or plumbing company that can actually help us identify the root cause and address it? ChatGPT gives me some likely culprits but don’t know who to call to investigate and don’t want waste more money bringing random plumbers in.
Thank you in advance for any referrals!!!
