In plumbing, the term "pressure balancing" refers to what?

The term "pressure balancing" in plumbing specifically refers to equalizing pressure in hot and cold water lines. This process ensures that both hot and cold water lines maintain consistent pressure levels, which is crucial for the proper functioning of plumbing fixtures. When both sides are balanced, it minimizes the chances of sudden changes in water temperature that can be uncomfortable or even dangerous for users, particularly during showering or when using multiple fixtures simultaneously.

In systems that are not properly balanced, a drop in the pressure of either hot or cold water can lead to various issues, such as scalding or cold shocks. This balance is particularly important in mixing valves, where both hot and cold water must be regulated accurately to deliver water at a desirable and safe temperature. Therefore, the role of pressure balancing is integral to ensuring a safe and comfortable water supply in plumbing systems.
