Frequently Asked Questions

Will this fitting work with my RV's existing water lines?

Yes. This is a standard 3/4" NPT fresh water inlet fitting that connects to most RV water supply hoses and internal plumbing systems. Verify your RV uses 3/4" connections before ordering.

Is this a direct replacement for my Dometic system?

This is an OEM Dometic part designed to match factory specifications. Check your current fitting dimensions (3/4" x 1-7/8") and part number 385311113 to confirm it's the correct replacement for your model.

Can I install this myself?

Yes. Most RV owners can replace an inlet fitting with basic tools. Turn off water supply, disconnect the old fitting, and thread the new one into place using plumber's tape on the threads. Tighten firmly but do not overtighten.
