Product Information

They achieve their purpose by creating an impenetrable physical barrier between the tap seat and the spout. The material construction of most tap washers also means that they’re able to fill and even out any irregularly-shaped voids between different parts of a tap fitting (generally the valve and the tap seat), effectively sealing off the tap spout from the valve. 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.

The next step is to release the valve, but first make sure the tap body is wedged firmly in position. If the body of the tap that sits on the sink or basin moves while undoing a tight valve nut, it may loosen the water connection underneath causing more leaks. Fitting an outside tap cover for the winter will reduce the chances of your outdoor tap freezing. New Build Outside Tap Not Working However if after visual inspection the washer itself looks badly worn, pitted or has deep indentations on its surface then it will need changing. When changing a tap washer, make sure that your new washer is exactly the same as the old one so that it functions the same. 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.

How Much Water can a Tap Leak?

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. 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. In terms of how to replace it, I'll look it up once I've got the tap, but any words of wisdom in the meantime would be much appreciated.

If there are any O-rings present make sure you change all of these also. Simply hook them off using a small screwdriver, measure the exact size of each one and then replace with those of the exact same size. 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.Once the washer has been changed then the next job is to make sure that the seat in the base of the tap it sits down on is flat and has no channels or wear in it that could cause leaks. Now that you know all about the different causes of a dripping tap and how to access the tap valve inside it’s time to strip your tap down and find out what’s going on. We have detailed below the full procedure for changing a tap washer and re-grinding the seat if that is also required. Step 1 – Turn off the Water These can be removed by grinding the rest of the seat down to level of these canals. This will produce a flat, smooth seat for the washer to sit on and seal the flow of water. More on this below. If you have turned the tap as far as it will turn and it’s not straight then you should remove the tap and add more PTFE tape. 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.
