Question:
Are the female threads on the drain trap 1.5 inch N.P.T.? I would like to evacuate from grey tank to outside of camper rather than from a sink, using pvc piping if possible.

Hey Kirk. The Camco RV Drain Hose w/ Drain Trap and Evacuation Flange item # CAM37420 works with a 1-1/2"- 11.5 fine threaded drain fitting. It'll connect but there's going to be gaps in the threads so it may leak. If you plan on leaving it connected you can seal it with pipe dope and not have an issue.
What kind of trailer do you have?
