Good afternoon. I have a question about a supply and return run to a section of baseboard I need to install. It's on the far side of a room and there are only two paths I can run the water to/from it. 1) In a exterior 2x4 wall for about 8'. 2) In the interior wall, but up, over, and down to...

Good afternoon, I am looking for some advice on a shower P trap installation. I just converted a bathtub to a shower. The shower stall trap sits lower than the tub trap did. The bottom of it is only about an inch from the bottom of the joist (the top of the horizontal drain is only about 3/4"...

Good afternoon all. When connecting a vertical vent pipe (dry vent, in this case 1.5") to a horizontal drain (in this case the shower drain, 2", with the shower trap about within 2'6" of the vent connection) am I required to use a wye & 1/8 or can I use a sanitary tee on its back? Does it make...

I'm sure this is plumbing 101 for you experts but I'm no expert. I've read that drains are supposed to be pitched 1/4" a foot up to 2.5", and pipes 3" and over are to be 1/8" per foot. Everything I see in posts here and overhear on the construction sites (I'm not a plumber, but I am in the...

I would like to know if it's acceptable practice to use a double wye horizontally for drains. I would like to use a 3" double wye, one of the branches would be the shower (bushed down to 2"), the other branch would be the wet vented w.c. (and two lav sinks beyond that), and the straight through...

Could someone tell me which fitting i am supposed to use when connecting two sinks in a double vanity? If you use a sanitary tee for one sink (connecting the fixture arm to the drain/vent) would that be a double sani-t for a double vanity? I am confused because there seems to be different names...

I would like to add a clean out wye to a horizontal wet vent under my bathroom floor. I would access it in the adjacent closet. I have learned from this site that no horizontal dry vent may be below the point 6" above the flood level of the fixture. I have also learned this wouldn't apply to a...

Good morning. I was hoping some of the professionals could look at my half bath drawing and let me know if it looks acceptable or what I've done wrong. I'm planning on wet venting the WC through the 2" lavatory drain because I can't get a vent to the toilet without at least a portion of it...

Is it acceptable that the vent leave the kitchen sink and pitch up away from it for about half the run, then turn down and pitches towards the washing machine & utility sink vent pipe? Any liquid in the vent will gravity drain, but some of the kitchen "vent liquid" (condensation) may end up in...

Good afternoon. I was hoping for a bit of clarity on a drain venting question. I have three fixtures sharing the same main horizontal drain but are connected to it with two different vertical stacks. They also share the same vent through the roof. Is it acceptable that the vent leave the first...
