Basics

A Tap is a valve for controlling the flow of a liquid or gas. It can refer to a valve for tap water ( faucet) to control the flow. Older style water taps for bathing, sinks and basins generally had separate hot and cold taps. A more modern tap design is the “ mixer”, a single tap whose handle moves up and down to control the amount of water flow and from side to side to control the temperature of the water ( achieved by mixing the hot and cold water together) Latest designs do this using a built in thermostat

What are the different types of Taps ?

a) Pillar cock - is the unit which is vertically connected and is meant for Wash Basins

b) Bib Cock – is the unit which is horizontally connected and is meant to go into the wall

c) Short body Bib Cock – is used for toilet area d) Long Body Bib Cock – used for bath area so that there is enough space for Bucket

e) Angle Valve – A shut off valve between the water pipes and a faucet. Its inlet connects to the water supply pipe in a wall, and its outlet is connected to the faucet

f) Mixers – is a hot and cold water intended for single tap-hole basins. Mixed water is supplied through a single fixed spout. A Pop up waste is included with some designs of tap. Pop up waste is a type of drain assembly for basins and bathtubs. When a lift or bath overflow plate lever is lifted, the pop up drain closes so the basin or tub retains water

g) Basin Mixers – mounted on to the basins are called basin mixers

h) Basin Mixers are of two types 1) Basin mixer without pop and 2) with Pop up

i) Wall Mixer ( 3-in-1 / 2-in-1) A mixer for hot and cold water standing proud on the bath rim, on pillars, mixed water is supplied through a single spout. A diverter valve is also provided, to send water through a flexible hose to a shower handset, which can be wall mounted.

j) Shower Head – Any device designed to produce spray pattern flow of water. ( The water spraying overhead nozzle in a shower)

k) Spout – This is the part that allows the water out of the system into the sink, bath, shower or basin.

l) Diverter – A valve redirects the flow of water to another application within a plumbing system. Its commonly used for diverting water between the tub / bath spout and the overhead shower

m) The water inlets normally have provisions for both cold and hot water. Hot and cold water are mixed manually by limiting the flow of cold and hot water to obtain an ambient water temperature

n) Waster Coupling – A drain assembly for bathtub / basins. The drain at the bottom of the Tub / bsin removes waste water when the tub is drained

o) Bottle Trap – Curved section of drain line that prevents sewer odours from escaping into the atmosphere. All fixtures that have drains must have a “P” trap installed. A toilet is the only plumbing fixture with an “S” trap

p) Flush valve – The part on the bottom of the toilet tank that opens to allow water to flow from the tank into the bowl. It seals the water into the tank or allows water to exit the tank for the flush cycle.

Ranges :

1. Standard Half Turn Ranges : Taps can be completely opened by just half turn ( 180 Degree) This range comprises of – 1 pillar cock ( or 1 Basin mixer) + 2 Bib cock + 2 Angle Valves 2 Concealed Stop Cock + 1 wall mixer ( or 4 way diverter) + 1 overhead shower

2. Quarter Turn Ranges : Taps can be completely opened by just quarter turn of the know ( 90 Degree) This range comprises of 1 Pillar cock ( or 1 basin mixer) + 2 bib cock + 2 Angle valve + 2 concealed stop cock + 1 wall mixer (or 4 way diverter) + 1 overhead shower

3. Single Lever Ranges : Taps can be completely opened by a soft pull of the Lever upwards

4. This range comprises of 1 Pillar cock ( or 1 basin mixer) + 2 bib cock + 2 Angle valve + 2 concealed stop cock + 1 wall mixer (or 4 way diverter) + 1 Spout + 1 overhead shower

Remember :

Never install the wall mixer above a bathtub on the same side where he / she will rest their head. The mixer can instead be fitted on the side where one’s leg rest and just above the waste coupling

Be careful of the length of the spout when using concealed shower fittings. He / She may hit the spout while getting up after having a bucket bath Install basin mixer with aerators. These aerators mix air with water and therefore less water ( hit and cold) is used for washing than by taps without aerators. The general impression is that ‘aerators’are used to provide “ foamy” water that feels nice. Aerators are primarily used to SAVE WATER.

Before buying taps, Ensure that they are smooth to turn Basin Mixers should have clear indications for HOT and COLD knobs Ensure that you have enough water head pressure when you install overhead showers. There should be about 3.5m (15ft) vertical head between shower and bottom of tank.

Suggestion for Maintaining Taps

It is recommended that Overhead Tanks must be cleaned regularly to avoid deposition of Solid Particle

Bends in pipeline account for loss of water pressure. Therefore keep the number of bends in the pipelines as low as possible.

All the Supply lines must have vent pipes. These vent pipes help in removing air-locking in the water supply to give a smooth flow of water from the fittings

Please clean the Aerators on the faucet outlet regularly to keep foam flow perfect Clean the fittings regularly with normal soap water or chalk powder or chalk powder to remove scaling / stains. Do not use strong detergents or Acids as this may cause damage to the chromium finish

Do not use harsh cleaning agents containing abrasives and acids, instead use a soft sponge or wet cloth with soapy water / diluted vinegar to protect the finish. Test the working of all concealed fittings installed on a high pressure for leakage before plastering or fixing tiles
