  What year trailer?  We have lots of info on the various toilets, but we need to know which toilet to talk about.

  I have a 2017 with the same toilet, which is the "Thetford Aqua Magic V". There are many threads about failed "toilet valves", but I can't find one specifically for what it means when the flush handle doesn't open the "blade" valve there in the toilet.

  When you operate the handle, is any water being put into the toilet bowl from the toilet valve?  Apparently: the toilet valve has a metal rod that connects to the flush handle.  When you pull the handle, the metal rod pulls open the toilet valve that allows water to go to the bowl.

  This link goes shows the Aqua Magic V exploded parts list, so have a look at parts 8 and 9.  (The valve and the small metal "link".

  This video at, about the 5 minute mark, shows the installation of a new toilet valve, and shows the little metal rod I'm mentioning.

  It would seem that the toilet has to come out to examine this.  There are a lot of Forum threads about replacing the valve that show the basic process, which is not hard.

  And, this is the Amazon link to the toilet valve.

  Plenty of owners have taken the toilet out and had a look around.  Don't hesitate to ask for more advice.
