I'm confused as I don't quite understand why a sanitary tee is necessary instead of the wye.However, the combination wye and 1/8th bend in the upper right corner of your picture NEEDS to be replaced with a sanitary tee. As it is, the trap will be cut off from it's vent when the lavatory drains.
Looking good- The drains -
Replace the combo tee on sink drain with a santee for the same reason you change the one for the tub
For the same reason you changed the one at the tub.Wow.
I see you already installed the wye on the stack. Good.
Remove the long sweep tee for the tub drain. That needs to be a santee.
Like the 3 X 2 you had in there before.
You're not the 1st one to do that.think I was many pages out of the loop. srry
That's why they call it a combonation fitting.I didn't know that a "wye with 1/8 bend" is similar to a combo.
All glued except for WC flange and tub santee, etc...Did you get all glued.
Was it mention earlier to glue the WC flange after the floor sheathing is laid so you can screw the flange to the floor.
Also you will want to block and strap the WC waste arm securely so you can't push it down or pull it up
Congrats on the new service plummer deal. Less BS is certainly better BS.if its only an inch you are looking to gain then Set the tub flange on a 2x4 and you will gain 1 1/2 inches for minimal effort, you will need to cover the face ( exposed side ) of the 2x4 with something like the tub surface, I have seen tub surround used for this perpose, but tile looks better and lasts longer.
Sorry For being out of the loop, I am now a full time service plumber ( got sooooo tired of commercial bs ) and am buisy as hell, and also loving it. every day is different .
