Understanding Shower Valve Types

The two primary shower valve types are mixing valves and diverting valves. Each has its unique features and purposes.

Mixing valves, also known as pressure-balancing valves, regulate water temperature by mixing hot and cold water. Diverting valves, on the other hand, allow water to flow from multiple sources, such as a showerhead and handheld shower.

Mixing valves are designed to maintain a consistent water temperature despite changes in water pressure or flow. They are ideal for homes with varying water demands, such as those with multiple bathrooms or washing machines.

There are two main types of mixing valves: pressure-balancing and thermostatic. Pressure-balancing valves maintain temperature by adjusting the water flow, while thermostatic valves use a temperature-sensitive element to regulate water temperature.

Diverting valves, also called three-way valves, allow water to flow from multiple sources simultaneously or independently. They are commonly used with shower systems that have both a showerhead and a handheld shower.

Diverting valves can be manual or automatic. Manual valves require you to switch the water flow between sources, while automatic valves do so automatically when you move the handheld shower.
