A dripping tap in Brent Cross, NW4 had been quietly wasting water for weeks β the kind of minor household fault that's easy to put off but adds up more than most people expect. Ralf attended to replace the worn cartridge causing the drip.
A tap dripping at roughly one drop per second wastes over 11,000 litres of water a year β a genuinely significant amount for what looks like a trivial fault. The cause is almost always a worn cartridge or washer inside the tap body: ceramic disc cartridges, standard on most modern taps, wear down gradually until they can no longer form a complete seal when the tap is closed.
The chrome shroud was removed to expose the tap body, and the worn brass ceramic disc cartridge extracted using pump pliers. A matching replacement cartridge was fitted, the tap reassembled, and the repair confirmed leak-free under full mains pressure. Most tap repairs of this type are completed in under an hour, and we carry common cartridge sizes for major brands on the van, meaning a same-visit fix rather than a return trip once a part arrives.
