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.


On the 2 Kohler different mixing valves I installed, the "adjustments" you
refer to on the left and right are merely shut-off valves, and are not used
for setting water temperature. Perhaps your Kohler valves work differently.
