How to FIX your Dometic/Thetford Toilet Valve:

Today we are going to learn 2, of the most common, RV toilets toilet valve replacements.
Dometic 300 series and Thetford toilets AquaMagic 5 &4.
The first thing we need to do is look behind your toilet and somewhere on the base is a tag. Take a picture of it so that you can blow it up a bit. That is your make and model for your RV toilet.
Once you have that information you can purchase the correct toilet valve.
I am going to post 2 YouTube videos' that will walk you through the process.
