: I turn on my hot water
: --the water comes out WAT too hot!!
: Then I blend my cold to a comfortable temp. But when I turn the cold off, water goes to med-warm.

: Is my hot TOO hot and why???

: Same with my sink, hot is boiling almost, cold brings it to an ok temp....turn off cold then I have lukewarm water til it goes back to boiling.

Johnny,
Turn down the thermostat on the water heater. They will adjust between luke warm and scalding.
