How to use it
- Match the faucet to the basin or sink: a pillar tap or basin mixer sits on a basin with a tap hole, while a wall-mounted tap needs a supply point in the wall.
- A mixer needs both hot and cold supply lines; a pillar cock or bib cock works on one.
- Check the spout height and reach against the basin, so the water lands in the bowl without splashing.
Installation
- Shut the supply and flush the pipes before fitting, so debris does not block the aerator or the cartridge.
- Seal threaded joints with PTFE tape and tighten by hand, then a final turn with a spanner; overtightening cracks fittings.
- A concealed (in-wall) mixer needs its concealed body fixed in the wall before the wall is tiled.
- Fit the faucet with the connectors and hoses the maker specifies.
Care and maintenance
- Clean chrome and coloured finishes with mild soap and a soft cloth. Abrasive powders and acid cleaners strip the plating.
- Unscrew and rinse the aerator now and then; hard water leaves scale that weakens the flow.
- A dripping faucet usually needs a new cartridge or washer, not a new faucet.
Buying tips
- Ceramic-disc cartridges outlast rubber-washer spindles and turn more smoothly.
- Coloured and PVD finishes cost more than chrome and need gentler cleaning.
- Homes fed by an overhead tank have low water pressure; check the maker’s minimum working pressure where it is stated.
