How does everybody show their p-traps in plan view? In the past, we have just not shown them and left it up to the specs to cover them, but ideally we would like to show them. I've been playing around with it and got it to look half way decent (I haven't used it in a project yet to know that it will work the way I want it too every time) but I'm curious as to how everyone else goes about showing p-traps in plan view and how you get it to look that way. I have seen another firm use a drop symbol with a rise symbol right next to it. I was going more for the typical half circle look.

Here is what I have so far.
