What do I do if my tap is leaking?

A dripping tap is normally caused by a worn washer.

To replace the washer, follow these instructions:
Turn off the water supply. Dis-assemble the tap by unscrewing the cross-screw situated beneath the hot or cold indicator on the top of the tap. Remove the tap body by unscrewing the headgear nut. To do this, hold the tap tightly in one hand unscrewing the nut with the other. Replace the washer at the base of the unit. Re-assemble the tap. Turn the water supply back on and check whether the tap is still leaking.


How do I unclog my sink?

The most obvious cause of a blocked sink is debris going down the plughole creating an obstruction preventing water from flowing freely down the plughole.

To unblock a sink, follow these instructions:
Try using a plunger first by covering the plughole with the rubber end of the plunger ensuring that it is covered in about a centimetre of water. Then cover the overflow with a rag and pump the wooden handle to create a suction. This should remove any obstruction. If this does not work, try dis-assembling the waste system under the sink:

 
 
Make a space under the sink and place a bowl or similar underneath the trap to catch any water. Dis-assemble the trap by unscrewing the top nut which is attached to the bowl and the second nut which is attached to the plastic waste pipe. Once the trap has been removed, clear any debris which has collected in it. Re-assemble the trap by reversing the instructions above.

What could cause my toilet to overflow? And how do I correct this problem?

If the water level in the toilet cistern gets too high, the only outlet for the water is the overflow pipe. A dripping overflow can be caused by a number of things. There may be too much limescale in the system or the float might need replacing if it is punctured or worn out. Alternatively, a worn valve washer may cause the water level to rise as the water leaks into the cistern.

.
Limescale
1. Limescale maybe caused by a build up of calcium from your water supply. Some areas of the country are more susceptible to limescale than others. In particular, if you live in an area which is very chalky, you are likely to experience limescale to some degree. To control limescale we recommend that you use a water softener periodically.

2. To replace an old or punctured float, follow these instructions:
Turn off your water supply. Drain cistern by flushing the toilet which needs the new float. Unscrew the existing float from the ball valve arm and replace with a new float.

 
3. To replace a valve washer, follow these instructions:
Turn off your water supply. Drain cistern by flushing the toilet which needs the new ball valve diaphragm. Unscrew the large plastic nut at the end of the ball valve arm to free the ball valve. Remove the old large rubber diaphragm from the ball valve and replace it with a new one. Re-assemble the valve and turn the water back on.

What is the proper way to unclog my toilet bowl?

If your toilet is blocked, follow these instructions to unblock it: Place the rubber part of a plunger over the bowl outlet and pump the handle gently. The suction created should force the obstruction down the pipe and clear the toilet. If the plunger does not work, try forcing an old sheet as far into the bowl outlet as you can. This creates suction which will hopefully remove the obstruction by forcing it down the pipe.
