    Purpose of vent under sink?

    There are bad smells that come from my sink drain when I run water. On inspecting (undoing) the U-bend trap, there is no debris or anything in there. It is a clean run. And I don't think the water is being siphoned out of the U-bend (though I can't be certain) because the sink is used a lot and...

    I'm remodeling our master bath. We have two 30 inch vanities with a 24 inch open space between them. Drain pipes go down into the basement of course but I'm wondering where a vent pipe would be. There is a bedroom above the plumbing wall and it's open right above this wall so it can't be...

They are the pipes that feed water back into the top of the tanks when there is excess, presumably from steam, expansion, etc. The one going to the cold...

    Hot pulling air through open vent.

    Hi, I'm new to the forum and just some background on myself. I have 4 years experience as a plumber but haven't worked in the trade in 15 years.

    Hi all, I have an old toilet on the top floor (to be removed) which empties into an outdoor vertical SVP and into the ground. The pipe is straight with a vent terminal on top. Another toilet on the ground floor empties through the suspended timber floor into (what I suspect) a drain. I wish...
