Learn the intricate process of modifying the plumbing system in Revit MEP to accommodate urinals without an integral P-trap. This article discusses the steps to edit the model, including trimming and deleting pipes, adjusting slopes, and adding pipe fittings, to achieve a functional plumbing system.
Key Insights
- The article offers a comprehensive guide on how to modify plumbing systems in Revit MEP in instances where the urinal does not have an integral P-trap. This involves editing the model by deleting and trimming pipes, and adding pipe fittings.
- The author emphasizes the importance of careful planning and breaking up tasks to avoid common pitfalls. This includes remembering to turn the slope on and off at appropriate times, and ensuring the correct system type is set before drawing pipes.
- While adjusting the system, it is advised to fix all of the urinals first before proceeding to draw the vents. This can help streamline the process and reduce the likelihood of errors.

In that previous video, we went ahead and got some of our toilets and our vent systems for our lavatories put in. Let's go ahead and jump up to our other bathroom here.
So I'm going to go ahead and jump up and we're going to have a little bit of an issue, but it's easily rectified. So one of the things that we had, we just kind of ran this straight out and I was kind of thinking, oh, the urinal for the urinal specifically, although we're going to have an integral P-trap, blah, blah, blah, blah, blah. But I guess these ones don't.
So there's a couple of different things that we could do. But what I want to talk about real quickly is how would we edit this system to try to maintain as much as we possibly can without having to do anything. Now we could say we want to install the vent down here within the vents underground.
It's kind of weird. We need to get a P-trap into here to go ahead and do that. Well, it's not too terribly bad to go ahead and do, but it's going to take a little bit of rework on our part.
And that's fine. Sometimes we'll have to come in and rework things. And sometimes I have found that specifically with Revit MEP is just deleting this entire aspect and then kind of going, okay, we're going to run it differently, how we tie it in rather than tying it in on here, we'll just kind of come in and come straight down, can make it work out a little bit better.
So realistically, sometimes the best way to go ahead and do this is I'm going to tab select here, select the fitting and delete it. I can trim these guys together to make that pipe hole again. That's kind of, that's kind of the easiest way to do it, but you want to continue to trim because then it doesn't mess up the slope of that pipe.
So here I would do this slight here, delete. Let's trim that together. Tab, select here, delete trim there and there.
Now once I'm in this section, what I can do is very similar to what we did with the lavatories. If you recall, we drew a short piece of pipe and then put our P trap it. So I'm going to go ahead.
I'm going to do that connector there. I'm going to go down. What do we do? I think we can go down like two inches down, three inches.
And there we are. I can place my pipe fitting come there, but, and we might need to actually move this up a little bit. We'll do something there and then right-click draw pipe.
Now let's see, is it going to give me, Oh, it gave me a snap. I do need to slope this down and let's see how it goes. There we go.
Now we've kind of just changed how that pipe connects. Now we can add in our plus sign for our event. So again, let me go ahead and go back and we'll just redo this a little bit faster.
So I'm going to go ahead and draw out of my connector here. This time, let's go ahead. Let's just go two inches down.
I think the pipe, the P trap grows in size a little bit. We're going to do that. I'm going to go to my pipe fitting.
Let's make sure we get the right end point. Perfect. I can select here, right-click draw pipe.
I'm going to be sloping down. There it is. And luckily it's giving me the snap.
So I go to that intersection, go over, go down, boom. And there we are. And then I can also add my vent here.
So then I can go PI, make sure that your system type is set to vent two-inch here, come up, go over there. Oh, make sure you change your slope. That's why I wouldn't want to go over is because I still had the slope.
So I could do the same thing here. Well, we'll do the second floor here in a little bit. I'm going to go ahead and go PI there, come up, go over, and there we go.
So because of that, because of how there's like, when you're kind of editing things and you're kind of doing things, sometimes I feel like breaking up these tasks is a really good way to make sure that you don't avoid any of those little common pitfalls. Like, oh, I forgot to turn the slope off. I got to turn the slope back on.
I got to do this. So what I want to go ahead and do is you notice that I had to turn the slope off to draw the horizontal portion. When I started the pipe command, I had to make sure I was back on vent to avoid those kinds of pitfalls.
I think it's easiest that we go through, we fix all of the urinals first, then we come back and draw the vents in. So I'm going to go to my level two plan. Let's see here.
I'm going to go ahead and let's see, where's my level two? Here it is. I'm not quite seeing my vent or my, my pipes and everything here. So let's go ahead and change my view range.
I'm going to go, uh, let's go level one. Let's go seven feet above level one. And there we go.
So here tab, click, select, delete tab, select, click that. And I can trim these guys back together, tab, delete. And there we go.
Now let's go down the line and I'm going to close my level two. I no longer need it. Let's go down the line and fix this before we go any further.
So I'm going to go here, zero space two. Let's go to my pipe fitting. P F should still be the P trap, draw a pipe, slope down.
There it is. Tighten. We're going to move our section just to do this a couple more times.
