I need to increase the maximum temperature on my older model Delta Monitor shower faucet. The Delta site describes how to set the "adjustable rotational limit stop" that's under the temperature control handle, but I can't figure out how to remove that handle to get at it.
My faucet is an older model than the Delta site illustrates; it would have been installed in 1999 or later. It has a large Lucite volume control lever with a smaller temperature control handle forming a domed cap. There's no visible screw on it; it looks as if it can pry off, but I don't want to wreck it by forcing it up.
Should I just bite the bullet and use a screwdriver to pry it off?
