Ever Replace a Toilet in an RV

[JumboJet]

I just had the privilege of replacing the 14 year old toilet in our Class A. The valve would stick and continue to fill the bowl, resulting in water on the floor!

It must be easy to install those when being built.

The water connection was on the opposite side of the new Dometic 310 toilet I installed. The manufacturer used a very hard PEX connection directly to the back of the old toilet.

Thank goodness for the PEX type connectors that are available at the big box hardware stores. I connected the toilet with a braided SS flexible hose too, like you would use in your house.

The space where the supply line runs is also the space for a heater vent hose, copper lines, PEX lines for the shower, and 5 Romex electrical wires. Careful cutting the toilet supply line!

Still need to finish the panel that covers all the space, but I will get that done this afternoon.

Just replaced the toilet that came in my MH with the 310 last month.
Splurged and bought the household style wooden seat to go with it. Well worth the money and DW is much happier than with the old plastic style

I replaced my 30-year-old terlet with that Dometic 310. Huuuuge improvement. Water line was in the right place, but the mount wasn't. Needed to get Dometic's riser kit that attaches to the existing flange and puts the mounting bolts in the right place. Puts it up another 1/4".

The stuff I found under and in the crevices of the old terlet was pretty nasty (in 1984 they put the toilets over the carpet, and there are lots of places under/in the old terlet for things to get "lost" - feminine hygiene products in particular). You're welcome.

Wouldn't that depend on the circumstances at the installation site? Sure it's nice to have an empty tank down the hole, but it's not really necessary, especially if you have everything staged ahead of time for a quick swap. Even if that's not possible, a rag wadded up over the hole works well while other prep work is done. Been there, done that, both ways...

Everybody probably thought that would be a logical absolutely first step in this process!

Replaced mine with an ADA approved model to help with our decreasing mobility. Had the dealer I bought the coach from do the switch. Best $$ I ever spent! :B

I think the job was easy especially with an exact replacement. May be easier than a home toilet.

I have to do the same. Just ordered a new stool because I was sick and tired hitting my knees to my chin all the tie I had to use the little plastic thingy.

That would have been the best way to go or if I could have found the replacement valve. I am hoping I have achieved a quality upgrade.

I installed the same porcelain toilet in two different RV's. Both required extending the water line to reach the new valve location, but since I always add an inline shut-off valve anyway, that was an easy process. In the first RV, the hardest part was removing the screws holding the flange to the floor and rotating it so the hold down bolts would line up properly with the new toilet. The second RV already had the flange properly positioned, making the whole job take only about an hour.

When I bought my new toilet a year ago they asked me which side of the toilet I wanted the water line connection on. I too used a braided SS flexible hose with a shut off valve. Easy install for me.

I replaced ours last year. All the water holes around the top ring were clogged with mineral deposits. Same issues you faced. Original PEX water line was on opposite side of toilet. I used a SharkBite fitting to connect the PEX tubing I had to cut.
