WebApr 9, 2024 · A check valve relies on a pressure differential to work. They require a higher pressure on the input side of the valve than the output side to open the valve. When the pressure is higher on the outlet side (or the input side pressure is not high enough), the valve will close. Depending on the valve type, the closure mechanism is different. WebCauses of Bad Check Valves. There are several reasons why check valves go bad. Some of the most common causes include: Age: Like any other plumbing component, check valves have a limited lifespan. Over time, they can wear out, corrode or become damaged. Water quality: Poor water quality can cause corrosion, erosion, and fouling of check valves. WebMay 14, 2024 · Basically, a check valve permits fluids such as liquids and gases to flow one way through the pipework.
