The aim of this is to get an idea of your tap water system, so you know if your maintenance engineer is doing their job correctly, if you attempt a tap repair yourself, be cautious, Obviously, changing a tap washer is a fairly common thing, but repairing the tap at the same time will extend its usage lifetime greatly. These steps will show you how to repair most tap problems.
I will go through it from top to bottom in a very simple yet effective explanation just pick out the stuff relevant to your situation. Initially, turn the water off to the tap, if you’re not sure how.
- TURN OFF WATER SUPPLY
Turn off both the hot and cold water supply under the sink. If this is not possible, you may need to turn off the water from your hot press or from the mains. Allow the tap to run until the water drains from the pipes.
- PUT PLUG-ON DRAIN
Put a plug into the plughole to stop any screws or small parts falling down the waste pipe.
- PRISE TOP OFF TAP
Using a flat head screwdriver, remove the cover from the tap top. Some are cover plates and some are bell-shaped screw-on covers.
- REMOVE PARTS
Remove the retaining screw, the colored indicator ring, and the handle.
Note: Inspect all parts, the spindle often has several o rings which should be free of splits and cracks, the thread should be square-topped not sharp.
- REMOVE HEADGEAR NUT
Using an adjustable wrench or spanner, loosen and remove the headgear nut. Note: When turning the headgear nut make sure you don’t turn the whole tap body, as this may rupture or strain the water pipe under the sink. Get someone to hold the tap while you use the spanner to turn the nut. If it is still difficult, apply a little penetrating oil to the headgear nut and let it soak in for 15 minutes. You should also grease the threads of the headgear nut before you reassemble the tap.
- EXPOSE FAULTY WASHER
Withdraw the jumper valve assembly to expose the faulty washer.
- REPLACE WASHER AND REASSEMBLE
Prise off the old washer, replace it with a new washer and reassemble the tap. Check the tap is turned off before switching the mains water supply back on.
