[VAC] Aqua Magic next to toilet

["My Airstream" <myairstream@xxxxxxx>]

I found a small drip coming from the area where the water hoses converge
above the Thetford Slide-O-Matic in my 66 Safari.  The leak seems to be
coming from under a small oval unit that can be seen from inside the
bathroom and is located behind the toilet.  It is called a "Aqua Magic" and
I cannot find any way to remove this casing to get better access to the
problem area.

Anyone know about this system?
