Hi everybody,
First of all: what an incredible forum this is!
In planning the PVC plumbing for the toilet and sink in our new bath room, I have the following questions -- see the attached image for reference:
* Does the toilet drain need a separate vent from the sink drain, or can I vent the toilet through the sink drain? I assume I have to vent separately, but I am not 100% sure.
* When venting the toilet separately, does this vent really have to connect to the toilet drain through a Wye? Can I not just use a sanitary T for this? I am asking this because in a Black & Decker plumbing book they connect vertical dry vents to drains through sanitary T's. They only use the Wye to connect the sink drain into the toilet drain.
Little bit of background: the plumbing plan I drew up only shows the hidden PVC portion. To this, I will connect a wall-mounted Duravit Darling toilet with Geberit water-tank onto the 3" drain, and a porcelain vessel sink with chrome P-trap to the 2" drain. The combined 3" drain connects to the existing waste line.
I really appreciate any feedback you can give.
Thanks so much,
- Erik
