We just got a new water heater installed in the basement, and the temperature in the 3rd FL shower is not hot enough for us. However, the temperature in the sink faucet on the 1st FL is fine and gets very hot, so that makes me think that perhaps the water heater temperature is fine. Would you suggest taking apart the shower handle, or would your first guess be something else? Shower handle is single Kohler shower handle.
