comment How can I rearrange this plumbing to drain correctly?
Thanks. I don't know how high it goes, but it goes well beyond what is visible in the photo. The kitchen sink in on the same line and drains well and the cat toilet only uses maybe a gallon of water at a time, so it sounds like it's time to open the wall (fortunately now behind a floating cabinet) and check the p-trap and vent. (I'll also install an air admittance valve on the stack if there isn't one.)

@Johnny, I can confirm, it's definitely NM-B, not an extension cord -- it ran to what used to be a 220V outlet for a dryer, now one side of it services a 20A 110V outlet and the other side is unused. If I ever have enough drywall pulled back again to get to it, I'll anchor it down better.

comment How can I convert a 240V dryer outlet to two branch circuits?
@chief, I was definitely planning to swap the 40A breakers to 20A, but I was planning to leave the 40A (10 gauge IIRC?) wire in place from the panel to the receptacle box, where I would then feed the GFCI with one hot leg and neutral and run the other leg and shared common and ground via 12/2 NM-B over to the new receptacles in the other room. Are you saying I should replace the existing 40A wiring all the way back to the breakers?

@chief, my city adopts NEC 2008 with some miscellaneous amendments, none applicable to this question. since the neutral is shared, I'm thinking I should still use a double-pole breaker (but 20A rather than 40A) so there's no question about the neutral having current moving through it. Maybe that's overkill, but I don't want anyone in the future working on one side of the circuit to become a shorter path to ground for the other side. I would guess that this is a good reason to label the shared neutral.

Wonderful answer, Greg, exactly what I was looking for! Leaving notes inside the box and at the panel are great ideas, I'll be sure to do that. But I do have a follow-up question -- since the 240V wiring was rated for 40A, what's the issue with the shared neutral carrying that load if the two branches were in phase? (I plan to use the same adjacent breakers as before, so it's not an issue for me, I'm just curious.)
