Options for a New Shower Valve

There are two main options for replacing your shower valve. They are:

  • Pressure-balancing Valves: They function by maintaining a steady temperature by equalizing the ratio of cold and hot water. These valves come with a diaphragm or piston which reacts to pressure variations inside cold and hot water pipes. This adjusts the flow appropriately to ensure you are not chilled after a sudden pressure drop in the opposite water pipe.
  • Thermostatic Valves: These are less common but offer excellent water temperature control systems compared to pressure-balancing valves. These valves allow you to conveniently adjust the water temperature without rationing the hot and cold water. They are designed with a heat-sensitive material that restricts the flow of hot water until it acquires an appropriate temperature for more hot water to flow within. This helps maintain a constant water temperature.

Any of them work well for your water needs in the home.
