Taps will be either operated by a single lever or with separate controls for hot and cold.
The internal mechanism of taps are called cartridges, or headworks, or tap inserts
Basin and Bidet taps use 1/2inch cartridges, most Bath and Bath/Shower taps use 3/4inch cartridges
Where there are separate controls for hot and cold the internals are either traditional multi turn screwdown compression valves or 1/4 turn ceramic disc valves. The internal ceramic discs look similar for both hot and cold but the hot turns clockwise to close and the cold turns anti clockwise.
Some bath taps also have a diverter allowing them to control both bath filling and use of a shower
Taps requiring a single hole to connect the pipework are called monobloc.
Where there are entirely separate hot and cold taps these are often called pillar taps, Where hot and cold come together from a single spout these are usually called mixers.
Kitchen sinks usually have mixers with a swivel spout.
There are a few Bath and Bath/Shower mixers which include a thermostatic control to automatically maintain the temperature.
In the UK most Bath and Basin taps are still mounted on the bath rim or the basin. Most Europeam taps are mounted on the wall.
Seal kits (usually for swivel mixers)
Dripping or leaking taps requires new cartridge
Wont divert between bath and shower, needs new internal diverter mechanism
Uneven or impeded flow may require new flow straightener or mousseur in the spout
Swivel mixers may leak around joint and require a seal kit.
