First Updated Video - How Dry Vents Can Connect To Wet Vent Plumbing Drain Pipes - Shower And Toilet - Project #1 - Q&#1https://youtu.be/oXeKlCgOgGY You should always check with your local building department to see what they approve.

Thank you sir, keep them coming

Thank you for sharing, it's a very specific topic considering, as you showed slight changes in drain length from fixture to main drain cause issue. However, it helps anyone to imagine how their specific needs should be approached. The 3D modeling is so nice to see compared to 2D scribbles on a dry erase board. Thanks again!

lol wow Im confused 😅 Gotta watch this a couple times

Oh my god, you just made this make sense about not wanting liquid to run through the top of the pipes, because that’s for the air

One issue is you can’t connect both fixtures at the same place. In many places double y’s cannot be laid on their side. This is because if you turn one side up slightly to get fall then the other side has backfall

In the first example if we added a separate dry vent before the toilet can we have the y directly under the toilet?

👍thanks for the video

Awesome video thank you

it will be better if each fixture has it is own vent where is the cleanout in that diagram?

In example #3, is it possible to have a soaking tub wye into the shower drain before it enters to the main 3" line? And with that in mind, how would this work with the vanity and tub switched sides of the room but the DWV 3" going the same direction?

Thanks! Very helpful. If someone is under IPC (Colorado), could you use one of these layouts in a basement with an AAV (like at the sink) instead of connecting to a stack?

No horizontal dry vents allowed below flood level rim of the fixture it's serving. the dry horizontal vent serving the toilet is wrong in example 10, also example 11 is wrong on the horizontal dry vent below flood level rim of the shower.

will this work also with a double vanity w/cross T??? tia

I see videos of venting through the roof because the pipe has to be vertical. Can we vent through the siding?

Can you hook up 2 toilet and 2 shower and 2 sinks in one 3 inches abs pipe? I just want to make sure. it’s all in underground one story house no basement it’s all under concrete if you can let me know please thanks . I can sand you pictures if you want thanks

SECTION 912 WET VENTING 912.1 Horizontal wet vent permitted. (2021 IPC CODE AND COMMENTARY) Note that fixtures connecting through a double-pattern fitting are considered to be independently connected to the horizontal wet vent. The individual fixture drains vented by a horizontal wet vent must enter the horizontal wet vent in the horizontal plane so that the connection is not below the trap weir of the connected fixture. Water closets, having integral traps that depend on self-siphoning, are exempt from this requirement. Other fixtures that are not vented by the horizontal wet vent (i.e., vented by a dry vent) can enter the horizontal wet vent horizontally, vertically or at any angle in between. Water closets, having integral traps that depend on self-siphoning, are exempt from this requirement. according to the 2023 IPC CODE and commentary. Water closets CAN enter a horizontal wet vent VERTICALLY because they depend on self siphonage AND they CAN but they dont HAVE to enter horizontally according to the information provided in this video However code in ur area may vary from code in my area, AKA take what I say with a grain of salt, especially if your state, province, etc uses UPC or any other plumbing code

I think you misspoke at 7:57. The toilet appears to be the farthest fixture downstream of the vent..

Heres something to ponder.... 912.1 Horizontal wet venting states every fixture must connect on the same level of the horizontal. In said section of the commentary the exception on the toilet. This is what it states.... "The individual fixtures vented by horizontal wet vent must enter the horizontal wet vent in the horizontal plane so that the connection is not below the trap weir of the connected fixture. Water closets, having integral traps that depend on self siphoning, are exempt from this requirement". With that being said saying a toilet draws air is not completely correct. A toilet pushes air when flushed that why a toilet does not need to be directly vented and limiting the distance for a toilet to vent is pointless... That would be section 909.1 Distance of trap from vent.
