Dripping taps


If a dripping tap cannot be stopped with a new washer it probably needs reseating.  There is a special reseating tool for this job.  Sometimes water finds its way behind the washer wearing a groove in the jumper this groove can be removed with a flat file. 
Newer taps will jamb altogether if the washer becomes flat and the inner jumper that carries the washer runs out of thread.  In this case the tap will need to be dismantled, rewashered and reassembled insuring that the retaining circlip is in place at the top of the spindle (see diagram).

Overflowing tanks and cisterns


Typical roof tank ballvalve, part2 type
 Ball valves are found in roof tanks and WC cisterns.   It is generally as quick and easy to change a roof tank ball valve as it is to re-washer it.  The older  “part 1” or BS1212 type ball valve should be replaced with “part 2” type ball valve readily available from plumber's merchants.
Ball valves found in WC cisterns are essentially the same as ball valves in roof tanks, although in low level and close-coupled WC suites they are often of the bottom entry type.  These are more difficult to replace so unless they are in poor condition it is probably best to re-washer.
There are many different  plastic float valves found in modern WC cisterns, often requiring specific washer. Sometimes it's easier just to replace the whole valve. This may not be without it's problems, sometimes the new valve will not fit within the cistern very well with the float touching the side of the cistern, the threaded shank not he same length and so on.
If you leave your house empty for more than a few days, roof tanks and WC cisterns can start to overflow so it’s worth thinking about turning the water off.

Outside Taps – No water






If you’ve turned on the outside tap after the winter and the water flow is very poor or does not exist it’s most likely that the non-return valves have become jammed.  Many outside taps now have two small plastic non-return valves fitted that will become damaged if the water in the tap freezes during cold weather.  There’s little you can do with these, you will probably have to replace the tap.  The best solution is to fit a non-return valve to the internal pipe work that feeds the tap.

Leaking Washing Machine Taps


Plastic lever washing machine taps that rarely if ever get used can be a problem when you come to have a new washing machine fitted as the taps will not shut off properly.  Usually it is the plastic levers that are the trouble as the plastic does not have the strength to turn the tap and becomes damaged in the attempt.  The answer is to remove the lever and with an adjustable spanner on the spindle that held the lever carefully close the valve.

Saving Water

Saving Water
One easy way to save water if you have an older WC cistern that flushes nine litres or more is to add a brick or half brick, which ever will fit best. The flush will be reduced by the volume of water displaced by the brick. You should place the brick so that it does not impair the movement of the ball valve float. Newer cisterns only flush six litres of water so adding a brick or other water saving device is not worthwhile and may cause you to use even more water, with repeated flushing necessary but many have dual flush buttons ;small button reduced flush; large button full flush.
I don’t recommend the use of plastic bags filled with water as an alternative to a brick as these will leak and you will end up with plastic stuck in the syphon. Plastic bags where used during the drought of 1976, we spent months afterwards extracting them from the innards of WC cisterns.
