It consists of a plunger and a diaphragm washer which are both situated inside a brass housing. The plunger is partly visible and protrudes from the face of the valve. Water enters the cistern via small plastic spout on the top of the valve which directs the water down into the cistern. The float arm is secured to the valve via a brass split pin.When the water level in the cistern rises, the float arm pushes the plunger into the valve. The plunger in turn pushes the diaphragm washer onto the valve seating, closing the valve.Part 2 ball valves are intended for mains-fed cold water storage cisterns and feed and expansion cisterns, and are by far the preferred choice over Part 1 ball valves. This is because Part 2 ball valves offer a much greater air gap between the water exit point on the valve and the water level in the cistern if it reaches "critical level", i.e. the same level as the pipe centre line. Part 2 ball valves also have a specifically designed mechanism for adjusting the water level in the cistern, whereas the only way to do so on a Part 1 ball valve is to bend the float arm.Current water regulations no longer permit the use of a Part 1 ball valve on a cold water storage cistern. While a faulty Part 1 ball valve on a pre-existing installation can be repaired, it should ideally be replaced with a Part 2 ball valve - especially if the old valve has a rigid tube which dips down into the water in the cistern. These `silencer' tubes are prohibited by water byelaws. **Q: May I know, What would be the length of the packet including Ball float shipping?** A: This item does not come with a ball / float. **Q: If the inlet washer is erroded what size do you need 15mm O ring ?** A: YES **Q: Does it have a filter** A: Good Morning, no this does not - it is a part 2 ball valve.
