    Any 2 in. x 2 in. x 1-1/4 in. x 1-1/4 in. Double Fixture Tee?

    Is there such double fixture tee with 1-1/4 inch on the side? I want to use a double fixture tee to convert single vanity to double vanity. But the stud width is narrow and only allow 1-1/4inch PVC pipe to penetrate through without disrupting the stud integrity. Obviously the 1-1/4inch will then...

    Using a Sanitary Tee as Vent directly connected to P-Trap trap?

    First pic shows what I believe would be a standard install. P-Trap + P-Trap elbow, connected to a vent. Second pic shows using a sanitary tee RATHER than the elbow that came with the P-Trap, functioning as both the P-Trap elbow and as the vent coming out the top. Are there any issues with this...
