A shower valve is a crucial component in a shower system that controls the flow and temperature of water. It allows users to adjust the water pressure and mix hot and cold water to achieve their desired temperature. Shower valves can be found in various designs, including single-handle and dual-handle options, making them versatile for different shower setups. These valves are typically installed behind the wall and are connected to the plumbing system. Regular maintenance of the shower valve is important to prevent leaks and ensure smooth operation. Common types of shower valves include pressure-balancing valves and thermostatic valves, each serving specific functions for user comfort.
