I have a shower stall with a single control knob that controls on\off (pull
out for cold and push in for off) and hot\cold (left for hot, right for
cold). The temperature setting on the gas-fired water heater is on the
"normal" setting. Other faucets in the house seem to produce a lot hotter
water when they run with only hot turned on. For a year or two now I've
had to keep the combination hot\cold on\off handle almost all the way
towards hot to keep the shower hot enough for a decent shower. I finally
removed the round knob and the escutcheon plate to see what it looked like.
There's a very small retangular cutout in the tile and the only thing
that's visible are the two holes that mount the escutcheon plate. The
diameter of the place where the knob mounts is a little bigger than the
diameter of a nickel, and it appears to have what looks like the same type
of fitting as with a garden hose valve when you remove the wheel handle -
it looks simply an on\off function - I didn't seen anything that looks like
other mixing valves that I've seen in pictures - nothing that looks like
any adjustment screws or the like.

Is this a situation where I simple remove and replace what the control
knob attaches to? When I go looking for replacement parts, what's the
proper terminology?

If it's going to involve removing tile and all that, I can learn to live
with it.

Thanks!


*On my Kohler there is an adjustment on the right and on the left for each
water input. Opening and closing each one determines the water temp. I
expect that you have the same, but since the opening is so small you cannot
see them. You could try a RotoZip with a tile cutting bit to open it up
more.
