wet vent

Hi all. Does this setup look feasible? I have an old home so am stuck with the layout. Main question is whether the 3" wet vent pipe connection between shower and toilet branches should connect to horizontal branch at 90 degrees. I am leaning that way since it's a wet vent. I am trying to go to...

Hello all, In the process of a remodel and I'm trying to wrap my head around how to vent the shower. The way I see it, I have two options based on where everything needs to be. Option A (red lines are my proposed runs): Option B: The shower trap will be too close to the wall to fork off of...

Hello, I am renovating my home by adding back-to-back bathrooms on the second floor. I have asked a plumber to do the plumbing. He came one afternoon and then he disappeared (after the first payment), and now I cannot find him :( . I am thinking to finish the job myself but I am worrying that he...

I am in the process of adding a washer and dryer on the second floor of my two story home. They will be located on the other side of the wall from a bathroom group (tub/shower, toilet, and lavatory) so I have relatively good access for routing the drains and supply lines. My question is what is...
