While dewinterizing I found that I had a broken flush valve on the toilet of my 2007 T-276SR. Here's what's involved in replacing it:
After turning off the H2O and opening up the drains to relieve the water presssure, you need to remove the cover:
Next you need to remove the two hoses from the valve. The supply hose has a threaded nut, and the discharge hose to the bowl pushes on and is held in place by a screw clamp:
Next you remove the two screws holding the valve in place:
You can see in the above photo where the plastic stem on the valve broke.
Here is a side by side of the new valve and the old one. Note the stem is now BRASS!!!!:
The new valve is screwed into place and the hoses reattached:
After reattaching both hoses, turn the H2O back on and check for leaks. Snap the cover back in place and you're back in service!!
Even with taking the pictures it only took twenty minutes.
Sorry for the quality of the cell phone pictures, but they get the idea across!!
