Dometic 310 Inlet Connection

Just purchased a 310 and trying to connect the waterline to it, I snapped off the fitting. It is a pex compression fitting. I am not finding a similar connection. I want to go to a shark bite as I added an in-line shut off. It appears like it is a 1/2" faucet type connector. Can anyone verify this? I tried a brass fitting but could not get it to stop weeping not matter how much little or a lot of Teflon tape I added. The brass fitting was just for a pipe.

I was really hoping that someone had the answer. We are taking off this week-end to camp.

A pic would help, but take it to your local plumbing store (not Lowes or Home Depot). They may be able to help.

Which fitting did you break? Are you talking about the line fitting coming from floor of camper or fitting on toilet? I just looked at my 300 toilet that I replaced in my camper and the only pex fittings are on the line that runs from valve up to bowl inlet. So I'm guessing it is the floor fitting?

Yes, this looks close to the fitting I need. I believe in the center of the threaded end, there should be a rubber washer to push against the tip of the male end to seal. I could not find this anywhere. It is the inlet supply. 1/2" pex to the male inlet.

This is a typical washer used for coupling to installed water connections for an RV. Google "rv water connection washers".

A faucet connection works(1/2”). Home Depot had a 1/2” pex with shut off to a 1/2” faucet that works great. It comes with a 12” braided steel line. 5 min. hook up and now have a shut off if needed.
