True or False: Some shower valves have a combination of thermostatic and pressure balance features.

The statement that some shower valves have a combination of thermostatic and pressure balance features is true. Shower valves designed with both features offer enhanced safety and performance. The thermostatic feature helps maintain a constant water temperature by adjusting the mix of hot and cold water, while the pressure balance feature adjusts the water pressure to ensure that the temperature remains stable even if there are fluctuations in the water pressure from other sources in the plumbing system.

This combination is particularly beneficial in preventing scalding and providing a more comfortable showering experience, making it an important innovation in plumbing fixture design. Such valves can be found in both residential and commercial applications, reflecting a broader move towards safety and efficiency in water delivery systems.
