What does a "back to back fixture fitting look like. I need to connect a 2 sink vanity together. Also this fitting needs to be similair to a 4 way tee so that I can drop a run for the drain and one up for the vent.

thank you

I went to HD today to look for the double fiture fitting to connect two lav's togther and the pics are what I found, is this correct?

also if it is the correct on what is the correct way of setting up the last pic.
Do I just use a 1 1/2 to 2" adaptor to connect into each side of the double fitting and a 2" to 1 1/2 reducer for the vent?

HD sucks. I needed the same thing and I ended up getting a 2x2x1.5x1.5 from Lowes. This way I only need one reducer for the 1.5 vent

You can use that fitting. The only drawback is that if you have a line clog and run a snake down either drain the snake will run straight across the tee rather than go down. A clean out above or below would alleviate that situation also.

I am no pro but from what I've read, the fitting you show in the picture is not the same fitting as the ones in the pics above your post. Notice the long sweep in the "above" fittings, and the short sweeps of your fitting.

Just like the poster I quoted said, the "snake will run straight across the tee rather than go down" - hence, so could the water - that's why in most places this short sweep fitting is not legal. It should only be used for dry venting, not liquid drainage.

I think what you need is a double wye and two 1/4 ells but like I said, I'm no pro.

cross

The fitting you show is a sanitary cross, and would be rejected by most knowledgeable inspectors. The correct fitting, a back to back fixture fitting, will come in a version with 2" on the bottom and the other three openings 1 1/2". There are also other configurations depending on the job's requirements. DO NOT use the cross.

That is the wrong one, and as I said previously, when you find the correct one it will have the proper sized openings so you do not need to use bushings.

A cleanout, even with the right fitting is okay...that doesn't make using the wrong one right, just overcomes one of the deficiencies.

So from what I'm reading you all say this is the wrong fitting or in some cases illegal???:confused:

If so I have been doing it wrong for 30 years. That is what we use for double lavs or back to back installations.
