Check casing for air leaks
Check for air gaps between casing and concrete
Check float adjustment and for waterlogged float or float rubbing on side of valve

Disassemble valve and check for sand or scale in valve rubber. Also check valve
orifice outlet for wear and damage. A screen or filter may be required with sandy or
scaly water

Check that valve inlet is not plugged or supply hose is not kinked
Check system pressure from supply hose by installing a tee and a pressure gauge
directly in front of the valve to check pressure drop when valve is open. A severe
pressure drop indicates a restriction or undersized supply system.
