Hi All,
I know that this is a well-covered topic, and all of that information is much appreciated. Based on previous posts, I think I have a possible solution to my problem, but would appreciate any advice you might have. I also wanted to say, that it is amazing that so many professionals are willing to help out DIYers like me.
I have attached photos below, but here is a summary of the situation. I am installing a 54" vanity in a 54 1/2" space (tight, I know). The vanity has two open cabinets (15"w x 18 3/4"h inside dimensions), with a set of drawers in the center (3 1/2" gap between back of drawers and wall).
The current drain pipe is slightly off-center on the wall, with 29 1/2" (from center) to the left wall, and 25" to the right wall. Based on other posts, it looks like I have 3 options:
1) Cut out the existing T connector (which will be fun, given the proximity to the double 2x4"s), and replace it with a wye.
Issue: The second vent pipe is 2" away from the one I'm working with (right), so I would have to immediately come out of the wye with a 90-degree and bring the plumbing outside of the wall to get past it. There is space, though I'd have to notch the back of the vanity, but this won't be seen, really.
2) Leave the current T connector in place to serve the right sink, then cut above it and add a second T (so 2 Ts, stacked vertically) to serve the left sink.
Issue: Besides the fact that there is already a 90 glued in, and I need to extend this further, the issue is that the second T connector is going to be about 4" higher, and the vanity cabinet is not that tall. Currently, the drain is 16 1/4" off of the ground; I will need to install the vanity 11-12" off of the ground (it's one of the floating ones), giving me about 5" clearance below the current drain, and about 13" above. Adding that second T 4" up reduces this to 9" for the P-trap. Doable, but tight I wonder?
3) Same as option #2 for the right sink, but then I cut a T into the left-most vent pipe for the left sink. In other words, the two sinks drain down different pipes.
Issue: This stack is either venting the kitchen below the bathroom or is serving the rough-in for a powder room in the basement. In either case, I don't really know the consequences of tying into this vent stack.
I would love to hear what the experts would recommend - one of these options, or something else? I've done lots of DIY plumbing in the past, but I've also called in a plumber when the work exceeded my skills, so if you honestly feel like this is one of those cases, let me know. Thanks in advance for your advice.
Please ignore the 30 1/2" marking at the bottom - that should read 20 1/2"
