Taps, mixers and cartridges
Traditional taps use rubber washers and ceramic-seated bodies; modern monobloc mixers use ceramic disc cartridges. Which one you have decides whether the fix is a cheap service part or a replacement tap, and hard water is the usual reason cartridges seize or weep.
Where a tap body itself is corroded or the seat is pitted, replacement is the sensible money: a new tap fitted with isolation valves takes less labour than repeatedly servicing a failing one. We will tell you which side of that line your fitting falls on.
