Tying in Sinks: Creating Hot and Cold Water, Drain, and Sanitary Aspects

Tying in Sinks: Creating Plumbing Connections for Hot and Cold Water, Drain, and Sanitary Aspects

Explore the process of incorporating plumbing fixtures into a design project, with a particular focus on sinks. Learn about the necessary components, like hot and cold water, the drain, the sanitary aspect, and the P-trap, and discover how to integrate and adjust these elements within the plans.

Key Insights

  • The process of integrating sinks into a plumbing plan is intricate, involving the creation of hot and cold water, as well as the drain and sanitary aspects of the sink system.
  • P-traps, a crucial component for sinks, require loading into the design system and attaching to a piece of pipe extending from the sink setup, with careful attention to orientation and placement.
  • Accurate placement and adjustment of fixtures and fittings, such as the hot and cold water pipes and the P-trap, are essential to avoid complications and ensure the plumbing system's effective operation.

In the previous video, we went ahead and finished tying in a lot of our plumbing fixtures, and now we're going to start tying in some of our sinks. So the sinks are going to be a little bit different.

They're going to require a little bit more work. We're going to have to create hot and cold water, as well as the drain and the sanitary aspect of it. I'm here on my Plumbing One plan.

We'll also need to include a P-trap on the sinks. We have not really worked with too many plumbing fixtures or plumbing fittings—pipe fittings—as of yet, but it's a pretty simple, pretty straightforward process. So let's go ahead and dive right into it.

So I'm on my Level One Plumbing. Make sure your working section is kind of over here. We're going to start down here on this lavatory.

But with this one here, just make sure your working section is down here. Make sure it's only getting one sink at a time. It can get a little wonky if you have multiple sinks.

So I'm going to go ahead and go into that section view. Again, any working section will work. I can right-click, go to view.

I'm also going to hit W-T. That's going to allow me to see both plan and section. It's very critical to see this here.

So what you have on the sink—on each sink—you have an in for cold and an in for hot. And then you have, obviously, an out for the sanitary. So to create the cold and hot water, that's pretty simple.

Now notice that I will have to go down. So I'm going to click on the connector. It's going to ask you which one you want to choose: domestic cold, domestic hot.

I don't care. I'm just going to start here. Go there, go down.

And then I'm going to come over. I'm going to turn my slope off. If you still have your slope on, we don't need to slope these.

So I'm going to do that. And then here, again, I'm just going to go down a little farther, go over. And there we go.

We've created the hot and cold water. Obviously, these are going to most likely be aligned, but you can see them in plan here and what they start to look like, right? So that's going well. What I'm going to go ahead and do here now is—I need to create my sanitary aspect, but I need to load in a P-trap first.

We haven't loaded any fittings in. So what I want to go ahead and do is, on my Systems tab, I'm going to go to my Pipe Fitting. I'm going to go to—whoops, excuse me.

If I hit Load Family, it wants to take me here. This used to be the way that I could go ahead and do it, but since the content is no longer loaded here, I have to go to that Load Autodesk Family. So I'm going to hit escape.

Let's go over to the Insert tab, please. I'm going to go to Load Autodesk Family. And we're going to go ahead.

You can just go up here and probably type in "P". So actually, first of all, we need to filter this down a little bit. It's still kind of sorted. I need to go down.

I'm back here at the base of this. I need to go to my Pipe here. And then that's where it's going to be.

It's going to be in Pipe, not in Plumbing Fixtures or anything like that. And I could navigate down to where you can see there's a lot of fittings that are in here. I can scroll all the way down.

I know I'm using a PVC Schedule 40 Socket Type DWV. I'm good there. So I can click on that, and then I can find P-traps here.

And I want to say it's probably just a Trap P right here. So I want to use that. I'm going to go ahead and hit load.

And there we go. Now to place this fitting in here, I do need to create a small piece of pipe coming out of this. So what I could do is select here.

I'm going to click on this to come down. I'm going to go down about three inches. So you can either zoom out to see three inches or you type zero space three.

And there it is. I'm going to go ahead and escape. Now I'm ready to put my fitting in.

So I'm going to go over to Systems. I'm going to go here to Pipe Fitting. I have my Trap P here.

And then when you go to place this, the snaps are not going to be directly on it. If you notice and I see that midpoint snap, I don't want to snap to that midpoint there. I want to go ahead and snap to the endpoint here.

So it's kind of off of it, but that's okay. And obviously I know it's pointing in the wrong direction right now. We can fix that once we place the fitting.

So I'm going to snap to that middle endpoint there, pick, and you want to make sure that turns green. That lets me know it's tied into that pipe there. Hit escape. And again, sometimes you have a little artifact here.

It's just showing you a pipe fitting. Now, when I select this, do you see these little, like, arrows that are turning? I can use that to change the orientation of this. So I could go ahead, turn this around, and I have to keep finding that arrow.
