Ok, here's what i've got under my kitchen sink (see pic).
I'm installing new countertops with an undermount sink. However, the PVC loop you see in the background (on the right, behind the main drainage line) is going to cause some interference with my new deeper sink.
I can't find anyone who can tell me what this loop does. It looks similar to a yoke vent except that it feeds back into the main line without an "exhaust line" venting outside.
Do i need to keep it? If i lower it on the top end by a few inches is that going to cause me any problems?
Thanks for any help!
PS - I'm on a slab. Don't know if this will make a difference to any recommendations but thought it might be relevant. House was built in '84.
