There are many different types of tap around and this is just one of themWith this design of tap the packing gland has been replaced with a rubber is ‘O’ ring. Once you have removed the tap operating head you will see that the water escapes cast the spindle if the tap is turned to the on position. Greenwich Plumbers fit washers to taps.To cure this problem:a). Firstly, isolate the water supply that feeds the tap to be worked on.b). Next you should remove the easy clean shrouded cover and remove the headgear from the body of the tap. c). There is a circlip located at the top of the valve that needs to be removed. You do this by using a screwdriver placed between the open edges and twisting very gently, thereby forcing it apart and then to slip from the spindle. Unfortunately this circlip is quite brittle and will sometimes break, in which case it will need to be replaced.d). Having now got the headgear safely in your hands, push on the top of the spindle, unwinding it and removing it completely from the brass housing, this will expose the ‘O’ ring.e). The old ‘O’ Ring can now be flipped off, which you will be able to do again using a small screwdriver. A Greenwich Plumber can refit ‘O’ rings.f). Replace the ‘O’ ring with a new one, applying silicon grease to provide a lubricant to effect a good seal.g). Now finally you can begin to reassemble the tap. Once you have completed the rebuild you should then test the tap to ensure that it is ok. If this repair does not resolve the problem it may be due to excessive wear of the spindle, in which case a replacement tap would be required.“
