Many years ago it was permitted to screw a pipe into the outlet of the valve so that it hung vertically below the level of the water. This solved the splashing problem, but concern about the possibility of water back-siphoning through the silencer tube into the mains supply led to rigid tubes being banned in favour of flexible plastic silencer tubes, which seal by collapsing should back-siphoning occur. A

This is often the result of ripples on the surface of the water in a cistern, caused by a heavy flow from the float valve. As the water rises, the float arm bouncing on the ripples will hammer the valve, and the sound is amplified and transmitted along the pipes. A flexible plastic tube once fitted will stop ripples by introducing water below the surface. If the pressure through the valve is too high, the arm will oscillate as it tries to close the valve, causing water to hammer. This can be cured by fitting something called an equilibrium valve. Professional plumbers such as
Waterloo Plumbers will know how to cure ‘water hammer’. As water flows through the valve, some of it is introduced behind the piston diaphragm to equalise the pressure on each side, so that the valve closes smoothly and silently.
