Basin Tap - Pillar Cock

A pillar cock is the plainest and most common tap in an Indian bathroom: a single deck-mounted body that stands in the basin's one tap hole and runs off a single supply. It is the fitting to use wherever the basin is drilled for a tap rather than fed from a wall mixer, and the least expensive way to put a properly made brass tap on a washbasin. Every tap here sits on a solid lead-free brass ingot casting under three plated layers, copper, then 10-micron nickel, then 0.3-micron chromium. A food-grade foam-flow aerator softens the stream, and the quarter-turn lever works over a ceramic disc cartridge rated beyond 5,00,000 operations. Prices run from around Rs 1,020 to Rs 1,520.

How to choose a basin tap

  • Check the basin height first. A standard pillar cock suits a drop-in or wall-hung basin. A countertop or vessel basin sits higher and needs a tall basin tap, or the spout is lost inside the bowl.
  • Count the tap holes. One hole takes a pillar cock. A basin drilled for three holes needs a centre-set or three-hole mixer, which is a different fitting entirely.
  • Single supply or hot and cold. A pillar cock takes one line. To blend the geyser and the cold line at the basin you need a single lever basin mixer.
  • Quarter-turn or screw-down. A quarter-turn ceramic cartridge opens fully in a quarter rotation and needs no re-washering. A screw-down tap is cheaper and eventually drips.

What lasts, and what does not

Three things decide how long a basin tap survives Indian conditions. The body material, because brass tolerates hard and chlorinated supply where alloy pits. The plating stack, because the nickel underlayer resists monsoon humidity and coastal salt air. And the cartridge, because ceramic discs stop the drip a rubber washer develops within a year or two. Day to day, the aerator is the part that needs attention: scale blocks it long before anything else fails.

Common questions

What is a pillar cock? It is the Indian trade name for a single deck-mounted basin tap that stands upright in the basin's tap hole and runs from one supply. Pillar cock and basin tap describe the same thing.

Can a pillar cock give hot and cold water? Only one at a time, because it has one inlet. Many Indian bathrooms fit two, one on cold and one on the geyser line. To blend them at a single outlet you need a basin mixer.

Why has my basin tap lost pressure? Almost always limescale in the aerator. Unscrew the aerator at the tip of the spout, soak it, brush it clean and refit before assuming the tap or the supply is at fault.
