I want to add a sink and dishwasher for a wet bar, to my existing rough in for the bathroom. I plan to saw cut floor and tap into drain for vanity with a wye connector. The vanithy is already vented do I need to vent the wet bar sink also. The run is a straight shot to vanity 2" drain. Distance is about 9' away. See attached photos. Thanks for your help

Hi

All sinks must have a vent that connect into other vents at least 6 inches above the flood level rim of the highest fixture on the floor... usually roughed in at 42-48" off finish floor. ALL SINKS

Never mind that the wet bar sink will be 9 feet away making it even more important to vent the sink. Here, code requires that a sink must have a vent within 4-5 feet of a ptrap serving that sink.

So, for good result and to keep to code add the vent. You won't regret it.

Glad to help Mike.

Looking good there. Frame work and plumbing have been done by PROS... my guess?

I am doing most of the work myself. Plumbing was done when I bought the house.
