Dometic Toilet Model Number

pokey · 10-02-2018, 08:09 AM

I need to replace the seal on the toilet in my 2003 Forest River Cardinal Fifth Wheel and do not see the model number anywhere? Does anyone know where it may be located? I used Thetford toilet cleaner / conditioner recently and worked fine until now. Thanks all

Unless the seal is damaged or missing, it can usually be removed, lubricated and replaced (with gloves). The model number is inside under the toilet. Most common are model 300 (plastic) or 310(ceramic).

It's usually down near the floor, behind the bowl. If you have a phone with a camera, you might be able to get your arm back there and take a pic of it.

I have a Dometic 300 toilet in my TT. The toilet info is on a tag on the right hand side of the base (as you look at it).

It was hard to see so I just slid my cell phone in the space and took pictures until one came out good.

Thanks all for the information. I looked with the light on my phone and didn't see it. The lable should be there as shown above so I'll look again. Thanks for the replies.

Thanks for the model numbers. I just looked again taking pictures with my phone and didn't see it anywhere. I'll order the 310 and that should take care of it. Thanks again.

I just watched a video on how to install a model 310. (It was a refresher as I’m planning on installing a 320.) I saw that the info tag was on the backside of the toilet.

I looked twice and took pics of the back and didn't see it at all. I ordered the 310 from Amazon and also watched videos on YouTube. It seems pretty easy. Thanks for the info.

The tag on my 310 is under the back of the toilet facing the floor, you need a mirror or use the front camera of your phone to see it.

For a little more $ you can get the 320 with the spray wand.
The landfills must be full of 300's.

The sprayer is very useful.

To help others that may or may not need to toilet seal replaced. I did order the seal to replace mine that was allowing water to seep trough. Reading the very easy to install directions the last step was to apply petroleum jelly or a silicone gel to the bottom of the gasket to assure a good seal. I decided to just apply petroleum jelly to the bottom of the bad one and it works great with no leakage period. If and when it starts leaking again I'll replace it with the new one but for now it works just fine.

Update that may help others with a toilet seal issue. I ordered a seal for the Dometic/Sea land toilet model # 320. Mine turns out the be a 210 series installed in older RV's. On the 210's the flush lever is on the left of toilet, the 300, 310 and 320 series the flush lever is on the right. The label showing the model # etc. on the 110, 210 and 510H series is located in the front by easily pulling out the lower front cover, the newer models have the info on the rear of the toilet.
