Question:
I have a 2015 Holiday Rambler 36DBT. I am trying to find a seal kit. The half bath has a Dometic model 712 toilet. Can you help with a bowl to base seal and a base to floor seal? It is leaking. Thanks

Hi Dale,
The replacement Toilet Bowl Seal Kit for Dometic 200 and 500 Series RV Toilets part # DOM53FR. The Dometic part number for the original replacement seals for the Dometic 712 toilet was 385310677. The 385310677-seal kit has since been discontinued and the replacement for it is the 385311462. The DOM53FR contains both the rubber flush ball seal and the rubber bowl seal that you'll need. I've linked a video of how to replace the seals as well in case you want to follow along or just need a refresher.
How long have you had your Rambler motorhome for?

I would recommend that you replace the ball and the seal both together. I replaced just the seal and it didn't help, I ended up taking it apart a second time to replace both.
