What is a shower system? Of course, it is different from the thermostatic shower faucet or the hot water pipe and so on, let us see the explanation of the person concerned. Usually, there are two kinds of shower systems, one is a pressure-balanced shower system, and the other is a constant temperature shower system

A pressure-balanced shower system uses a pressure-balanced valve, you only have one lever, it's you on/off function that only controls the water temperature, not the volume. When the valve opens, it stays open (2.0 gallons per minute in California). You can't reduce the amount of water that comes out, but you can always use an adjustable shower head to vary the pressure.

A thermostatic shower system uses a thermostatic system and you usually have two levers or controls. One lever controls the water temperature (thermostatic valve) and the second lever controls the water volume and on/off function (volume control valve). The system allows you to set the temperature once and for all so that it is set the way you want every time you shower. You can also adjust the amount of water flowing out, but 2.0 gallons per minute is still the maximum. Such valves are more complex and therefore more expensive than pressure-equalizing valves.

With either system, you can add a diversion function to your shower. A diverter allows you to have multiple shower heads (or a tub/shower combination). Today, a "one-piece" valve is available, combining the diverter, volume control, and thermostatic valve on a single escutcheon plate for a simpler look.
