Unexpected Water Temperature Changes? A Pressure-Balancing Valve Could Be the AnswerIf you have ever experienced the surprise of a sudden temperature change while taking a shower, you can understand why managing water pressure changes is important. The key to preventing pressure and temperature changes is a pressure balancing valve, also called a pressure-compensating valve. It's a plumbing device designed to reduce the likelihood of thermal shock and scalding while showering or bathing. It's also a safety device that is required by code in most cities.
The pressure-balance valve works by sensing the hot and cold water pressures coming in from the supply line and compensates for temperature fluctuations to maintain a consistent water temperature.
Without a pressure balancing valve a sudden change in water usage, such as a flushing toilet or clothes washer turning on, could send a burst of hot water to a shower or bath, causing the potential for injury.
If your plumbing system is older and not equipped with a pressure balancing valve, call MR Plumbing. We can upgrade the plumbing system to prevent unsafe temperature fluctuation.
