Went to flush the Tecma toilet, the water went into the bowl but the flapper on the bottom did not retract to let everything out. What's the fix on this one ?
Here's the link to the schematic and parts list for your toilet. http://www.thetford.com/part/tecma-silence-plus-rv/ It looks complicated, I had a similar problem with my Thetford Aqua Magic Style II toilet but mine's a lot different from yours.
