Toilet replaced.

[Happycamperscolorado]

replaced the thefton toilet this weekend with a dometic 320. a little pricey but happier with it. just not sure of Lowes quick connect pipe fitting for it. think i will look at finding a shark bite fitting to using instead. not use to the 'push the fitting on and no leaks' option. use to sweating pipes and this is new to me. fingers crossed

Understand completely, we will keep an eye on our non shark bite fitting for the first few trips out.

Replaced our Thetford with a Dometic 310 last November. Was apprehensive about the sharksbite type shutoff valve. I bought a flexhose with toilet fitting on one end and a sharksbite type shutoff valve on the other. Tried using that and found out the Dometic 310 needed the same assembled hose with a SINK type fitting on the one end. Everyone has said you need to make sure the pvc cut is square and clean. Well, its four months later and we have been using it daily (snowbirds) and no leaks or drips. Bought the assembled hose with fitting at Home Depot for around $16. I would assume Lowes may have the same fitting. Best of luck.

I use the Flair-It brand fittings and valves just like your Coach came with. Cut the PEX slide on the nut over the Pex insert the barbed into the line tighten the nut easy to remove have been using for 10 years never a leak

Dennis, good luck with those fittings. I just didn't have good luck with either type from the big box stores. Mine actually would hold for a week or so and then the water alarm would go off and we would find it leaking.

I finally gave up and had my plumber come by and put professional ones on. Of course he had all the correct crimping tools for the professional grade pex fittings. No more leaks.

I have a question about the Dometic 320. I replaced the Thetford with a Dometic 320 late last year and didn't get to test it out until this spring. Question: After flushing, and removing foot from pedal, the valve seems to slam shut so hard it causes the water in the lines to slam. Is this normal ? I'm concerned of the water slamming in the lines that it may cause joints to work loose. And, the higher the water pressure, the louder the slam. It does this either with the pump or city hookup.

Terry, my 320 did that a few times than got quieter. Things are good now, but I also put an adjustable regulator on the park supply because they have been running in the 80 psi range off and on. I have this set to 60 psi. John

I also installed the 320 and it makes a slamming noise. I think the noise is coming from the anti-siphon valve. I think it has a very positive closing. At least I hope that is what is causing the noise. When used in the middle of the night it is a little annoying.

One does get used to it and until you get used to it or it gets quieter...it is reassuring to know that you're not getting out of bed onto wet carpet and standing water in the bath. Been there, done that. John

kdeiss ... the last couple of model years, the factory has moved away from the barb with a screw on nut connectors to fittings that require a metal crimp band. This seems to be an industry wide move. I liked the old screw nut fittings as I never had an issue and I didn't have to have a crimp tool to do water line repairs.

I dunno what some on the MOC are doing wrong trying to use the press loc type fittings. We use them successfully by the hundreds at work at about twice the working pressure of RV water lines.
