When I run water down the sink drain in my kitchen, I get a hydrogen sulphide smell in my living room.
Past years, I've tried hydroxide drain cleaner, boiling water, some Zep enzyme stuff from Home Depot, and can't think of what else. Oh, yeah, a slug of hydroxide based coil cleaner.
I don't put any grease in the drain, though the last people were fond of beef, from the smell of the oven. They moved, in 1993.
This Am, I rinsed a dish in the sink, and was blasted by hydrogen sulphide smell in the living room. Any ideas what to do next? That sulphide smell is getting worse. Only happens when I run water down the kitchen sink drain.
Went to the roof, flushed a bunch of water down the roof vent. The vent about 1 inch ID swollowed all the water I could run out of my garden hose. So, it's not likely a clogged roof vent.
What else might solve the problem, and end the sulphide smell in my living room?
