Sorry for this dumb ass post but my next door neighbor lady has a 6 month old kid, husband is out of town probably until September, she has a sewer gas leak and the city told her to stay out of the house until it's fixed. I'm no help, the first plumber who showed up had no idea what to do, the 2nd broke a camera trying to find the leak. She's staying with her parents but is sort of at wits end. Anybody got a suggestion?
