ABC’s of Plumbing – Pressure Balancing Valve

The Pressure Balancing Valve, also called a pressure-compensating valve, is a plumbing device designed to reduce the likelihood of thermal shock and scalding while showering or bathing. It’s a safety device required by code in all localities in the Southwest Florida area.

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 ABC Southwest Plumbing & Air Conditioning. We can upgrade the plumbing system to prevent unsafe temperature fluctuation.
