Discover the step-by-step process of installing vent pipes in a plumbing system, including the placement of mains, adjusting the pipe size, and determining the path for the pipes. Gain understanding of how to overcome challenges such as offsetting pipes, modifying elevation, and using tools like the trim, extend multiple elements feature.
Key Insights
- The article provides detailed instructions on installing vent pipes in a plumbing system, from running mains close to the plumbing chase wall to running them vertically through the roof.
- Adjustments might need to be made during the installation process, such as changing the pipe size due to the number of pipes tying into it, adjusting the middle elevation, and offsetting pipes that are directly over the top of one another.
- The article also highlights the importance of tools such as the trim, extend multiple elements feature in making minor adjustments and achieving a tighter, neater system.

What we can go ahead and do now is we can go ahead and put our mains in for our vent pipes. So what we're going to end up doing is we're going to have our mains kind of running down kind of closer to the plumbing chase wall. We'll connect all these over and then we'll run it into our little chase that we have back here and then run vertically through the roof.
So what I'm going to go ahead and do is I'm going to go to my plumbing, my level one plumbing, and actually let's go to our ceiling plan because we're going to be up in the ceiling now. So I'm going to go to my ceiling plan here, my level one ceiling plan. What I'm going to go ahead and end up doing is I'm going to go to pipe and we might want to upsize this.
We'll make it a three inch just because we have so many pipes tying into this. I'm going to change my middle elevation to be 10 feet. There we go.
I'm going to kind of start wherever the farthest one is 10 feet, slope off vent. There we go. And I'm going to kind of run it along the path that I want it to go.
We're going to go up that there. And then what I can do is I'm going to extend. So modify choose that multiple extend boom, boom.

That doesn't want to work quite right. So what I could do here, if I really wanted to, is I could say, well, maybe I want to 45 this off, draw a pipe. I think I drew a pipe placeholder.
Actually, we don't want to 45 that do not do that. We'll have to, we'll have to do some other things here. So what I want to do is right click, draw pipe.
We'll just bring it over. There we go. So this is kind of the end of the line here.
So I could delete this. Now, if I wanted to, what I could do is I could also, you know, how we had the plus sign, I have a minus sign. So I could remove that so that then I could go ahead and just have it be just a bend there.
We're going to have to kind of do a little bit of offset with these because these are directly over the top of one another. Well, actually we could probably do a T let's see here. Oh, we could do that.
Nope. It doesn't want to. We're just going to offset these boom, boom.
We can also offset it like a 45. I kind of like the 45 a little bit better. And I'm going to switch this to wireframe really quickly so I can see everything.
We just need to get these just off angled a little bit so that they don't tie into the vent directly there. Okay. Perfect.
If you wanted to change these to 45, you could easily do that. I could delete this fitting, make this a 45 and then trim it up, delete this fitting, drag this over to 45 degrees, trim it up. And if you want to slide this back, you could also do that.
If you wanted to slide these back so that your system is a little tighter, you could, and you can always make those minor adjustments. Now I'm going to go here to the trim, extend multiple, select here, go there, go there, go there, go there, go there, go there, go there, go there. Perfect.
So down here, what I'm going to end up doing is I need it. Now we're going to go down to this pipe cavity. So I'm going to draw my main in again.
So I'm going to go to systems pipe slope off 10 feet vent. Good. Again, I'm going to kind of run over the top here, come into that space, go there.
I'm going to take these guys. I'm going to go ahead, draw a pipe. I'm going to 45 down a little bit, just to offset select here, right click, draw pipe.
Let's go ahead and 45 down a little bit. I don't want to 45 from the, from the wall because trying to go through that wall with an angled is not a good thing to do. And again, if you wanted to adjust these, you can just grab them and drag them back.
There we go. Now they're all at the same elevation. So I'm good to go to my modify tab, trim, extend multiple elements there.
Go, go, just go keep going down. So since I ended it, that was kind of an interesting thing. I've actually never really had that happen.
When you trim, extend, and I picked there, you're going to want to kind of go since I went all the way down like this, what ends up happening is that this pipe splits. So I can still connect them, but for whatever reason, it didn't do it. So you might just want alternate your sides when you're going down.
Okay. And there we go. We've tied that in.
Let's go to our second floor. So our second floor ceiling plan, what I'm going to end up doing is I'm going to go, I'm going to draw both of the mains first. So systems pipe, let's go to my three inch vent.
There we go. Again, we're going to be going up the same path. We'll actually be tying into the same vertical.
So I'm going to go about right there. Oops. Make sure I'm in the right elevation because I was actually below.
Make sure your middle elevation is 10 feet. Make sure it's on vent, which it is. There we go.
And then let's go down here. Same exact thing. We're just putting in that vent main.
