  • Dometic 320 toilet

    After seeing the Dometic 320 toilet upgrades several of the folks at the Hiawassee Rally installed, I ordered me one from Amazon. So I'm home when the UPS driver deliveries it, the box looks okay, but when I look inside:

    It must be in a 100 pieces. The ceramic was completely shattered. Amazon is replacing if of course. But the unusual thing is that they took my word that it was broken and didn't want to see this picture. They don't even want it back for proof. I'm just supposed to trash it.

    This sound a lot like 7.3 Fords experience.

      Sounds like UPS should know about it.

        It is a great toilet once you get one in on piece.

          It will be worth the wait for the second one to show up.

            How about an installation question while we wait for the non-broken toilet to arrive.

            I know I will have to make some adaptor to connect up the supply line because the Thetford line is in a different place. I've seen 7.3Ford's blog pictures and he did it with all PEX pipe and 90 deg elbows. I have a shutoff valve where the supply comes out of the floor. What about cutting the old connector off just above the shutoff valve and put a Sharkbite push-to-connect 1/2" NPT male connector on the PEX and then just use a stainless steel flexible 1/2" NPT Female to female hose to connect up to the 320??

            I'm not a plumber, but that seems easy enough and the flexible hose gives me some margin in the routing.

              Well I was all wrong or completely misunderstand plumbing standards. I saved the water connection from the broken Dometic 320 and headed to Home Depot. Nothing fits that 1/2' connector, except a threaded Swivel PEX connector. Standard PEX 1/2 NPT female connectors will not screw on. Something to do with the fact that the toilet male connector doesn't have threads for the first 1/16". The Swivel PEX connector threads on easily all the way up until tight.

              I took a picture of the old toilet water connection and wondered if the Thetford connector would fit the Dometic 320. If that were the case I could get a standard push-to-connect Sharkbites 1/2" elbow and coupler along with a foot of 1/2" PEX and that would be a lot easier than buying or renting a PEX crimping tool.

              Anyone know if the old water supply line is going to fit the 320?

                Research on another forum points to the fact that both Thetford and Dometic toilets use the exact same 1/2" NPT plastic water supply connector. I think I'm going to remove the short piece of PEX with the Swivel connector from the Sharkbite shutoff valve and just use 1/2" PEX pipe, a Sharkbite elbow, and a union if needed to fit the current swivel connector on the the 320 toilet.

                This may sound like a lot of detailed thought for a simple job, but plumbing is something I know very little about. I don't think twice about electrical, but what do you expect from a retired electrical engineer.

                  Hi Jim, they are the same. A 90 degree sharkbit will do fine.

                    Well the 2nd 320 arrived by FEDEX Ground and I got it installed. Very simple job. I did more waiting and thinking than actual work. Since I already had a Sharkbite Push to connect ball valve shutoff, I just had to rearrange and cut the pieces to connect 2 - 90 deg. elbows and the old swivel connector. I also bought a coupler and 5' of 1/2" PEX, but didn't need them. I still have to mount the sprayer holder to the wall, but want to think about where.

                    Fun Fact: I thought about saving the old Thetford Aqua Magic II at least until we've been camping once with the new 320, but getting it out of the truck and safely back into the garage didn't work. Just as I was bending over to set it down on the floor one of the parts I was holding broke and the whole thing crashed to the concrete floor into a hundred pieces. I should have taken it to the dump along with the packing cardboard for the 320.

                        plumbing ues a principle much like electrical except that it does it better downhill.
