I have a bathtub drain that is draining too slowly, I've tried a few actions, see below, not getting any improvement in drain flow. With 5 gallons of standing water in the tub, when I push the drain lever down it still takes a full 60 seconds for that water to drain, no difference. [b]Chemical Actions:[/b] I've used several treatments that I have poured down the drain, let them sit for a 30 mins to 2 hours, and then flush them out with warm water, including a ZEP enzyme treatment, Pequa, straight Vinegar. No difference. [b]Auger:[/b] I then used a power auger with a 1/2" head on it and bent the head a little so it spins a little wider than the 1/2" and power augered down the drain (using a power drill) for a length of 3 feet. I felt no clog resistance, and when I pulled it out there was no debris stuck in the head. Any good ideas of something else I can try? Or could this just be the normal rate of water draining? Would the rate of flow be faster if I enlarged the drain holes in the drain cover a bit? Thank you!

I'm going to be adding a drain for a freestanding tub about 3' from an existing shower drain, parallel to the wall where it connects to the sanitary drain. I won't be extending the 2" ABS from the shower drain as the joists run opposite direction. So, I figure I'll run a new 2" drain from tub to the sanitary line in the wall. I'm still wrapping my head around the varying venting requirements, etc. Any insight on that? I figure I'll have to have the new 2" line vented (I think?), but can I join that new venting to an existing vent in the attic before it heads out the roof? Any good references out there to read up on/watch? Every Ptrap needs a vent right? Thanks!
