Any advice would be appreciated.
Here is the new set up. It was all done with 1.5 inch ABS, which is the same as what was in there before. I was not able to upgrade to 2 inch without ripping out all kinds of walls downstairs. Everything is sloped properly.
Problem: If I fill the tub, and then drain it I get major gurgles from the shower drain. Seems to me that the pipe fills up completely and it is trying to suck air from the shower drain disturbing the water in the trap and making a loud noise. It also shakes the pipe down to the basement. There is no problem with the tub running, only if you fill it. Basically the drain can keep up with the water flow coming from the supply pipes, but not if the tub is filled. There is no issue with the shower draining.
The previous set up was almost the same but used a double wye fitting where the tub and shower connect. It was located in the middle of the room inside a shower wall. When I removed the old shower wall to have an open shower I moved the vent into the side wall of the room and reconnected it the same way in the attic to the existing vent.
Thoughts:
1. Could there be a blockage in the vent in the attic or at the roof. The tub and shower have not been used in 6 years. Would it be likely due to the lack of use that a bird or something made a nest or something made it's way in there?
2. Is there a way to slow down how quickly the tub drains? Is that a legitimate solution? I know it works because when I put my fingers in the drain to slow it down, the problem stops.
3. Everything is tiled now, so it's going to be very hard to redo anything aside from wrecking walls and ceiling underneath, but I welcome any suggestions.
