Basement Toilet and Shower


Basement toilet and shower rough in in the planning. Is there a chance that the horizontal section of the vent could clog in this arrangement. Nothing is finalized yet.

Yes, Vents cannot join as you show. Must be 6" above the flood rim of the fixtures served before joining them

Holy @^#%^$% batman.




To add to the code reference above : Unless precluded by structural conditions (I don't see any), then the vent must be run as high as possible, before offsetting horizontally, and must be run on grade at 1/4" per foot slope with drainage fittings.

Also : Pretty sure you can't do that with your shower tailpiece, but i'll let someone from your area chime in on that. Ours have to be vertical only.

Still in planning stage. No rush. How about this? Fittings 3 and 7 are rolled a little bit off the horizomtal.

Is this what is called a Flugglehorn? Always wanted to play a Flugglehorn.

By my code, those vents should be coming off the top of the drain pipe, meaning 45* angle or greater. This means you have to hit the wall first with the drain, vent up, then travel to your trap & or trap arm.

If I were trying to get this plumbing done, i'd have asked for the concrete to be opened up on the other side of the wall as well so my tie ins could be over there, vent up in the wall, and then be more of a straight shot to where my drains are located.

Yeah I was afraid of that. Guess I will have to demo more of the concrete in the laundry area (which I wanted to not do) and move the double-wye (fitting #1) back.

Thaks for the constructive advice and not just making fun of my work of art
