Seat leakage is defined as leakage that is internal to a valve-between the inlet and outlet sides of the valve-when the valve is in its closed position. It is not limited to leakage across the valve seat, but also encompasses all leakage across the valve trim when the valve is in the closed position. Leakage across internal trim seals, such as piston rings, and across trim-to-body seals, such as gaskets, can be counted as seat leakage. It is important to note that, while leakage through valve stem packing is of growing concern in the industry, governing industry standards address this type of leakage separately and do not consider it to be a form of seat leakage.
To prevent air leakage from a Schrader valve in your tire, you can ensure the valve cap is securely tightened, check for any damage or debris on the valve, and use a valve core tool to tighten or replace the valve core if needed. Regularly inspecting and maintaining the valve can help prevent air leakage.
It's possible for a valvestem to bend or break, but the most common failure is for the seat area to deteriorate and leak, requiring the valve and it's seat to need refacing.

This is a procedure done to restore the valves and valve seats. This is done typically when having a head(s) reconditioned.
It is a gasket (a seal) between the valve cover and the head that prevent the leakage of oil, and protects the valves from dirt.
Your tubeless tire may be leaking at the valve due to a loose valve core, damaged valve stem, or improper installation of the valve. It is important to check and address these issues to prevent further air leakage.
Your bike tire valve may be leaking air due to a damaged or worn-out valve core, a loose valve stem, or a puncture in the valve. It is important to inspect and replace the valve if necessary to prevent further air leakage.
To determine if the temperature pressure relief valve is leaking, check for any signs of water dripping or pooling around the valve. If there is evidence of leakage, it may indicate a problem with the valve that needs to be addressed.
Valve shutoff classifications refer to the ability of a valve to completely stop the flow of a fluid. The classifications include "tight shutoff," which means the valve can fully stop the flow, and "loose shutoff," which indicates some minimal leakage may occur even when the valve is closed. Different valve types and designs offer varying levels of shutoff capabilities based on their intended use and operating conditions.
Common issues with a no-flapper toilet include continuous running water, weak flushes, and water leakage. These problems can be resolved by checking and adjusting the water level, cleaning or replacing the fill valve, and ensuring proper alignment of the flush valve. Regular maintenance and timely repairs can help prevent these issues.
