Autodesk Revit - Easy Peesey P-Traps

On a recent job I need to create server P-Traps, these were big ones on 120mm pipe, but the way the default family works in Revit is not easy and you cannot Automate the way in which they are placed, but with a little modification you can create a p-trap that works on a routing system.

The first thing to do is to create your pipe work, in this case a 40mm waste from the bottom of the sink and then though the wall.

The P-Trap that I had loaded was from the standard Revit library from under the Pipe-Fittings-HDPE.

If you edit the family and look in the properties you will notice in the properties that it’s part type is set to multiport.

Change this to an Elbow, then load back into the project

Now click on your bend under the sink, you will now be able to change this in the dropdown to a P-Trap. Job Done
