What affects shower performance?
The shower's top priority is to keep the desired water temperature constant. To
maintain this temperature, the shower may have to automatically change the rate of
water flowing through the appliance. Any of the following conditions can cause the
shower to change the flow rate (force of the shower) in order to keep the temperature
constant. Most changes are minor and will go unnoticed.
