Hello all,

I am planning to add a bathroom to a bedroom. The new one will be about 20 ft or so away from the existing one.

I am in San Jose CA.

Would I need a vent pipe for this new bathroom?

Thanks!

Curious and googled this:

Maybe a bitch to go through.

I know I could find our county's codes on line but took a bit of trying.

Short answer, Yes.
Venting can get pretty complicated but a general rule is if the fall
of the drain pipe is more than the diameter of the pipe you need a
vent. Basically you need a way to break the vacuum created when water
flows through the drain pipe. They do make a studor vent, essentially
a check valve that breaks the vacuum but some building departments
hate them. I don't think you can use them on a toilet at all.
The real answer comes from the building department but I bet they will
want to see a vent typically on the stack from the sink.

If the new bath is on the top story or if it's single story, an additional vent is no big deal.
If not, I think there are other alternatives, like a widget that acts as a one way air admittance
valve. Whether you can use one of those for a whole bathroom though, IDK.
