I have a tee for the air uptake and a elbow coming out to the laundry sink after the tee for the air uptake.
If I move the elbow after the air uptake tee making the distance of approx. 5 inches to 7 inches, will this make a difference or does the air uptake have to be before the elbow for laundry sink.
I live in Howard county maryland, will this be within CODE.
got a picture?

I am not a plumber but I'll take a deep breath and try to answer your question. First I'll assume your laundry sink is in basement and your "air uptake" is vent. The vent is either 3 or 4" pipe if it is used as drain from upstairs. If it is smaller pipe, then it is probably for vent only. Now, the sink has a trap and it leads directly to the vent/drain (called a stack). If the stack is far enough away from the sink, a separate vent for the sink may have been installed. This vent line will be above the sink drain pipe tied to the stack. I plumbed mine this way, although the stack was not that far from the sink. If you eliminate the vent, the sink may have drain problem and have problem keeping the water in the trap, to keep out the sewer gas. If you are moving the sink, you can cut out the vent pipe in the same length as the drain pipe and reattach them using hubless connectors. Get a plumbing book from a library and look at the diagram of drains and vents and how they work together, and that probably answer your question directly. Hope this helps.
