The valve seat is the non-moving part of a valve against which the moving part, or valve plug, disc, or ball, seals to stop or regulate flow. In plumbing, valve seats are found in faucets, water heaters, and other valves, ensuring a tight closure when the valve is closed. Valve seats can wear down over time due to corrosion, mineral deposits, or friction, leading to leaks or reduced flow control. Regular inspection, cleaning, or replacement of valve seats is necessary to maintain valve performance and prevent water wastage.
