Discover the intricate process of connecting arm overs to branch lines in a library area, with each step meticulously documented. Learn about the importance of adjusting pipe diameters, creating riser nipples, and the precision required in aligning and connecting pipes.
Key Insights
- The process begins with adjusting the diameter of the branch lines to one and a half inch, ensuring proper functionality and compatibility with the arm overs.
- Riser nipples, vertical pipes connecting the main to the branch line, are crafted with precision. This requires the careful selection of sprinklers and the meticulous connection to the branch line.
- Attention to detail is critical in this process. This involves adjusting the height of sprinklers, capping open ends, aligning the pipes properly, and making precise estimates for elevations to ensure proper connection and functioning within the system.

Let's wrap up this library area connecting our Arm Overs to our Branch Lines. So let's zoom into this piece here. Currently, we have a piece of half-inch pipe at 14 feet, the elevation is okay, but let's go on ahead and set this to one and a half.
And we can do that to all of our Branch Lines. Let's set all of them to one-and-a-half-inch diameter. Okay, that warning is fine.
All right, next step is we need to connect our Arm Overs to the Branch Lines. And we're also going to be creating Riser Nipples, which is a vertical pipe connecting our main to our Branch Line. So what we can do is let's go to the sprinkler, connect into, that's fine.
Now, if you recall, it's going to use a piece of half-inch pipe, but we're going to fix all of these once we do this run of the Branch Line, and we'll do the same thing for each Branch Line. So again, it's a process of selecting the sprinkler, connect into, select the Branch Line. Okay, now in this case, we talked about why we aren't going to go all the way extended there because we don't want to go through that roof slope.
So in this case, let's click the sprinkler, right click, Drop Height, one inch, go up to about there. All right, and that should work. And let's go ahead and cap that.

This sprinkler, we're actually going to have to connect from this Branch Line. Let's go ahead and take a look. So let's take our section, drag it over here, and let's flip it the other way with this button there.
Go ahead, pull back. So as you can see, we have this sprinkler right here. So I'm going to Drop Height, one inch, we'll bring it up to about six inches is okay.
We'll go over. And in this case, we'll have an outlet facing down. And there we are.
Okay. Now, before we move on, let's clean up a little bit, we'll go to this, we will cap the open ends. Now let's go to this section.
Now we can see here's our main and here's our Branch Line. Let me pull this section back so I'm not going through that outside wall. Okay, so what I want to do here is I'm going to click on my Branch Line.
And we're going to choose Create Similar, find somewhere hovering over the main. Again, we'll use the Align tool after this. If it's not exact, that's okay.
And we're going to draw straight down. Now we can go to our Align tool. Go ahead, select this.
Now if we try to drop straight down from this view, it's not going to work. We'll have to go back to our Piping Plan. And this guy, we will set up here going forward for all the rest of these configurations.
There we are right here. We're going to drag this down. So as you can see, it's a little too close.
So this we gave ourselves some wiggle room. Again, sometimes our estimates for elevations aren't going to be exact. So that's fine.
This is why we can do all these things in Revit and keep our connection. We're at 13.6. Let's bring this down to 13.4 to give ourselves some more room. We're still up above the ceiling.
We're still fully connected. Now we have enough room to get this piece in there. So again, this is our riser nipple connecting our Main vertical pipe up to our Branch Line.
Okay, let's go on ahead and save.
