Venting Sink
We have a sink with no vent. It had one originally going all the way to the roof but someone disconnected it and filled the vent with tar. The sink waste line does connect to the main waste line in the house, which I presume/hope!!! has its own vent. Do we need to vent this…

Do we need to vent this sink, and how do we do it, who does it, and how many billions will it cost? The sink is near an outside wall.
Thanks, everyone!
When I bought my house, before I did an extensive renovation, the ground and Parlor floor duplex had a “gas” problem. The tenant complained of the smell of gas, we had the gas company in but they couldn’t find a leak. It DID really stink there sometimes but it was more of a sewer gas smell. When I finally started the renovation and did demolition, we discovered that the kitchen and bathroom sinks weren’t vented and just fixed it as part of the plumbing work we had to do. I think that it created a really unhealthy situation; sometimes I couldn’t believe how nasty that place was.
“I do mainly worry about blowing up”
unlikely. while sewer gas contains methane, you’d be driven out of the house by the smell long before it reaches explosive levels. and a kitchen drain would be soon refilled under normal kitchen use. otoh, if you go away for 2 weeks just as the trap empties…(kidding)
btw, i didn’t mean the actual sink drain size but the pipe which connects it to the rest of the plumbing.
