The first thing a plumber in York will do when he encounters a dripping tap is to turn off the water. He will be aware that at this point the pipes are still full and therefore the taps must be turned on in order to drain away any water that remains.
The next thing to do is to disassemble the tap. There are many different shapes, sizes and types of tap in plumbing, however most of them can be removed by popping the top off in the center of the tap and then removing the screw underneath. The plumber should now be able to remove the tap easily.
Sometimes it will be necessary for Plumbers to remove another section by unscrewing it in order the access the actual tap; in other designs around the York area the tap will be immediately accessible.
Next an adjustable spanner is used to loosen the tap so that it can be easily unscrewed by hand. Once the tap has been removed, the washer can be replace by simply unscrewing the retaining screw, removing the washer and replacing with a new tap washer of the appropriate size.
The tap can now be put back into the housing, taking care not to over tighten it, which can cause damage if not done carefully. Once everything is back in place the plumber must first make sure that the tap is off before turning the water supply back on. Now he can check to make sure that the leak has been faxed and that the tap functions properly.
