My home is a two-family, so there is a kitchen in the basement. When a large amount of water is dumped down the first floor kitchen sink, it backs up into the basement kitchen sink.
But not always. Only sometimes. Can't figure out why it happens when it does, and why it doesn't when it doesn't.
Meanwhile, there is a constant sewer-like smell in that basement kitchen.
I had a drain guy come out and he snaked the basement kitchen drain and replaced the caps on the trap located nearby in the basement floor. The smell went away for a while, but then it came back. He came back and did it again, and the smell went away for a while. But now it's back. Again.
He says the smell is not a sewer smell. But it's not a normal basement smell either, and it's coming from that basement kitchen sink.
What could be causing this? It's not dry traps, because we checked that.
Thank you for your ideas!
