Fixed the drippy kitchen 'mixer' tap AGAIN. One of those with the ceramic discs in. The cold supply started dripping about 6 months ago, bought new 'cartridges' but they were too long. Butchered it and used one of the ceramic discs and a new 'rubber washer' to fix. Same has just started with the hot tap. Fortunately, everyone was out, so I had time to turn the water off and drain the hot water down without getting moaned at.
There are many different 'sizes' of these cartridges, with very minor differences. Other option, at the time, would have been to turn the water off, then disappear for an hour to a DIY store, then come home to lots of complaints the water is off. Why are there never any 'stop' taps on sinks ? Only ever on toilets !
Anyway, job jobbed.
