urinal with internal p-trap

Total1

I'm buying a used urinal with internal p-trap , from the back out the urinal is is 1 1/2 inch abs . Do you need another p-trap or run it directly into the main plumbing stack ? Thanks people . ( great forum here )

I doubt it needs a separate trap. You might want to check with the manufacturer. But whatever you do, don't p**s off the plumbing inspector (couldn't resist)

Just like with a water closet, the internal trap is all that's required.

You'll need a urinal flange, gasket and bolts to connect it to the waste line.
