Toilet Fill Valve Inlet Filter Screen is used for stopping sand and scale at the toilet cistern fill-valve inlet, where a single grain on the valve seat keeps the toilet running and wastes water. EN 14124 is the reference cited for it on drawings, datasheets and purchase orders.
What EN 14124 Means for Toilet Fill Valve Inlet Filter Screen
The dimensions in the table below are supplied to suit EN 14124. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.

Specifying Toilet Fill Valve Inlet Filter Screen Beyond the Standard
- Thread: G 3/8 or G 1/2 to match the valve tail.
- Mesh: 40-mesh catches valve-seat debris without slowing refill.
- Form: Cylindrical screen inside the tail, or a cap on bottom-entry valves.
When Toilet Fill Valve Inlet Filter Screen Is Not the Right Choice
Not a scale preventer; very hard water still scales the valve seat over time.
