Defect

Cause/Action

Dripping tap

Change washer with washer of same type. Should washer not stop dripping, tap may require reseating or renewing.

WC cistern

Possible corrosion of parts, new washers may be required. NB: it is sometimes quicker and cheaper to renew complete siphon system.

Overflows running

 

Ball valve letting by. Replace washer, clean out foreign bodies/renew ball valve. NB: water is valuable and scarce so repairs should be made as quickly as possible.

Water slow to run away

Trap under sink/basin blocked. Remove trap, clean and refit. If the trap appears clear the waste pipe may be blocked, or there may be a back fall or corrosion in the waste pipe.
