Changing a set of taps.
In principle, the methods for changing basin, sink or bath taps are the same. It should be noted however, that there are an infinite number of types and designs of taps available. For the purpose of this guide I shall use basin taps on a standard two-hole basin as a reference, as these are what I consider to be the most straightforward due to relatively easy access compared to sink or bath taps. As with every aspect of construction/D.I.Y., there are several ways to carry out the task successfully, however this description is written with the novice or beginner in mind, so the method, tools and materials will reflect that.

The first, and most important task is to ascertain where to isolate the water supply from. Open up both the hot and cold basin taps, this way you will know straight away whether or not you have isolated the supply. Check underneath the basin to see if the pipes leading up to the taps are already fitted with isolation valves like these:
If they are, it is simply a case of using your slotted screwdriver to turn the centre screw to the horizontal position, as shown. The water supply will now be isolated, and you can safely continue work.
If there are no isolation valves present, you will need to turn off the water supply to your entire home. This is achieved by first locating the stop cock:
