Question for you plumbers

[Tim Larsen]

This is for my home.
I am adding a half bath in a bump out. I would like to avoid a VTR in the bump out as it is near some upper windows. The new toilet will be be physically in line with the old with a sink upstream from there.

Venting ideas?

TIA,
Tim

Is there any reason you can't put a vent line above and behind the added sink location that ties in top the existing vent?

I wondered where my pool vac hose went!!!

[Michael Larson]

Jeff, Is that your attic?

[Tim Larsen]

Mike, the way the bump out will be attaching to the house, it would be very difficult to get the sink vent over to the existing vent. Especially since the main stack is encased in 6" of sprayed icynene. I may just have to add another stack - as far from the windows as I can get it. But it would be nice to avoid it.

[Michael Larson]

Tim, does your state allow AAVs?

You could have an AAV at the sink if the new toilet is within the allowed distance(varies by jurisdiction) to the vertical stack.

[Tim Larsen]

If it's legal in the IPC, it's legal here. I've thought about the AAV. It's in my bag of options. The new toilet might just make the 6' distance to the vent.

Huh?

Did you mean venting or gaseous emissions control

That's funny. I liked in the instructions where it says to drill a hole in the wall to run the electrical to an outlet in an adjacent room...

Seems to me that it would be inefficient due to leakage as there is no a s s gasket included.

I am wondering if this is real myself.
Power cord may be low voltage ,which makes through wall acceptable.
Think Doorbell and phone.

I would add a studor vent in the wall between in the wall between the two bathrooms located behind a access panel.
