How To Connect A Dometic 310 RV Toilet To A Supply Line That's Too Far Away

Updated 11/14/2022 | Published 11/12/2022

Question:

We are converting an old thetford toilet to a dometic 310 toilet with NPT connectors. The placement of the rigid tubing doesnt work, its at least 4 inches away and has no give at all , we clearly need flex hose or something to be able to work with the angles. We do have 1 female 90 degree plastic elbow, extra rigid hose and a small connector coming directly from the toilet ...but would really prefer flex hose...is this part, or option available?

You'll just need to run to your local hardware store and grab a supply line to connect your Dometic 310 Part-Timer RV Toilet # DOM37FR to your water inlet. I had to do the same in the attached video below when the new toilet I was installing had the supply line connectors on the opposite side compared to the old setup.

There are a variety of different connection types so you'll want to see exactly how the hose will need to connect to your supply line. The hose I got had a "shark bite" fitting so I just pulled the old connector off the supply line and pushed the new hose on and connected it to the toilet.
