How do I adjust hot water limit stop in single handle shower faucet?
I have an American Standard single handle shower faucet in my downstairs bathroom that we finished about 6 months ago, and I cannot figure out how to adjust the hot water limit stop so that more hot water flows (I have hot water at will every where else in the house, including the sink in that bathroom, so I know it's not a water temp problem). Haven't had to use it until this weekend, only to find that I only get luke warm at best, and of course I cannot find the installation manual nor do I have the model # to search for the manual online. I did review a number of other American Standard manuals online, and all seem to be consistently the same, but not sure the instructions for adjusting fit my model.
I have removed the handle and faceplate, but cannot get the cap off to open access to the stop ring. The cap appears to be affixed to the unit somehow. I can look into the small opening of the cap and do see the stop ring tabs, which are red, and can see the white tabs that turn with the handle and hit the stop tabs. I was able to get a small screwdriver in the opening to try to move the stop ring, but couldn't get it to move. I didn't try to force it too much because I didn't want to break anthing.
