I have a year old Fleetwood mobile home that has 2 shower heads in a stall shower, the diverters have a lever which pulls up, then left and right.

The water temperature can be adjusted with great care to a comfortable temperature, but moving the lever less than 1/8" results in either direction gives a temperature change that makes you jump out of the way.

Is there any way to adjust the amount of mix inside the diverter? Or anything short of replacing the diverters which will allow me to adjust the temperature normally.

Thanks

While many mixing valves have an anti scald device or limiter there isn't much you can do to make the valve slower to react to movement of the handle. Do you know the brand of valve or can you post a pic?
