There is a huge amount of different types and sizes of washer and O-ring for all of the various appliances and applications they could be used in and this is no different when it comes to taps.

Insert the grinder into the tap body and tighten up the threaded section into the top thread. To start cutting, push down on the handle twisting as you do. What type of tap washer should I buy? The one aspect that tends to cause more confusion and uncertainty than any other regarding this question is often getting the correct sizing. Remove the grinder periodically and run your finger around the top of the seat, you will feel any remaining indents. Keep grinding until it is smooth. A dribble from the top of the tap is usually a result of the Gland seals being worn. Sometimes there is a gland nut, which can be undone to reveal the O-ring sealing the gland to the head. (see “Individual elements that make up a pillar tap” image at top). Other times there is a circlip holding the spindle to the head. This can be removed carefully as shown below. Some valves have a small retaining nut for the washer, as the one in the image below has. Some have the washer simply pushed on to a centre lug. Either way, now you have got this far, you may as well change the washer weather it’s worn or not. Most washers are symmetrical and turning the old one over will give you a new surface to work with so don’t do this.

The traditional method of doing this is shown in the image below. It works by placing a cloth over the spout of the tap to avoid scratching the metal and gripping it with a pair of Stilson Grips. As you turn the spanner on the valve you can then hold the whole tap steady and stop it moving with the Stilson Grips. In a pillar tap, when the handle is turned to turn the tap on or off, the washer is either raised or lowered by the spindle on to the seat. The seat is a ledge in the base of the tap body that the water flows through. When the washer is closed down on to the seat it creates a seal stopping water flowing, but when raised the seal is broken and the water is allowed to flow. To remove the tap head, simply prise off the tap indicator cover and remove the retaining screw beneath it. Once the screw is removed the tap head should then simply pull off.

Be very careful when doing this and also ensure that wherever force is being applied you have added additional support to compensate. Leaks can also be caused by the valve seat in the body of the tap. Over time, due to the pressure of the water it tries to force its way under the washer and little by little it erodes the brass from which the seat is cast. Tiny little canals are formed in the seat which allows water to pass under the washer and out through the tap. Flip the cap off the top of the headgear or if you have a handle, locate the retaining screw and then remove it and then pull off the headgear or handle exposing the valve. Rubber tap washers are another popular choice for sealing many types of bath and sink taps. Sealing washers in rubber are sold at a wide variety of standard sizes - common requirements include the 15mm rubber washer, 1-inch rubber washer, 32mm rubber washer and 40mm rubber washer.

On most tap indicator covers, if you look closely around the edge you will see a little recess. Using a flat edge screwdriver, insert the flat edge into the recess and wiggle it under the cover and prise it up. In some instances there won’t be a recess so you will just have to use a very small screwdriver and gently slide it under the indicator cover to prise it off, being careful not to damage it.There might be debris or jointing compound paste inside the tap or maybe in another pipe fitting before getting to the outside tap that was left on by the plumber who fitted it. One of the most common problems encountered in the home is a dripping tap and it remains one of the most misleading as the go to solution is to just change the tap washer, but this isn’t always the cause. The problem in some cases is the valve seat that the washer sits on when the tap is closed. A cold winter causes boiler condensate pipes to freeze as well as outside taps and will keep plumbers very busy. This is also the case when it comes to O-rings. Again depending on the type of tap you have will depend on what size O-rings are used, if any are used at all.
