What does a pressure balancing valve do?
A pressure balance valve works by maintaining an equal amount of water from the hot and cold side. Sudden changes in water pressure may reduce the water flowing from the showerhead, but the temperature will remain the same. Temperature: Provides scald protection and maintains temperature within 3 degrees (+/-).
How do you adjust a pressure balance cartridge?
Grip the front of the cartridge and pull it out. Rotate it toward the hot side, which is usually counterclockwise, to increase the maximum temperature. Rotate it the other way to decrease the temperature. It should snap into place when you let it go.
What is the difference between a thermostatic valve and a pressure balancing valve?
A pressure-balanced valve uses a shuttle piston to balance the hot and cold water pressure, even when one line has a sudden loss in pressure. A thermostatic valve actually measures the temperature of the incoming hot and cold water, and adjusts the amounts of each to maintain a constant temperature.
What does it mean for a shower to be pressure balanced?
A pressure-balanced valve provides water at nearly constant temperature to a shower or bathtub, despite pressure fluctuations in either the hot or cold supply lines. It has a diaphragm or piston inside that reacts to relative changes in either hot or cold water pressure to maintain balanced pressure.
How does a balancing valve work?
Dynamic balancing valves work as flow limiters. They are set to a desired flow rate and ensure that a larger flow rate does not take place. If the pressure in front of the valve increases, it will close some more, so the pressure loss across the valve becomes correspondingly higher.
How do you adjust shower valve temperature?
Adjust the Shower Valve
- Remove the handle. You may need a screwdriver to do this.
- Take off the metal cover beneath the handle, exposing the valve stem.
- Turn the RSL two notches in whichever direction desired, then put the RSL back in place.
- Replace the faucet handle, then test the mixture of hot and cold water.
