Basic fittings in the water distribution line
These are fittings in water lines to regulate flow through the lines and are an integral part of any water distribution system.
Taps –
a tap is what we see at the draw off end of water service line. Depending upon the directions of water entering the tap and coming out of the tap, they may be categorized as:
1. BIB TAP – It has a horizontal inlet and free outlet in the form of a bent tube called bib. The bib prevents dust from entering into the free end and contaminating water when it comes out.
2. PILLAR TAP – It has a vertical inlet and horizontal outlet through a bib. They are designed for use in lavatory basins and baths.

3. GLOBE TAP – It has a horizontal inlet and vertical outlet. Previously, these were used in baths and are now largely replaced by pillar taps.
4. SELF CLOSING TAP – This type of tap open when either pulled up or pushed down. Left to itself, it will always close by spring action. It greatly helps in reducing wastage.
5. SENSOR OPERATED TAP – Has a sensor which operates when it detects movement in front of it.
For the convenience of guests, the hot and cold taps can be distinguished by a red spot and blue or green spot respectively
VALVES
It is a plumbing device that is used for stopping or fully opening supply to a line or fitting.
They are put in line with the pipe line.
Valves are fitted throughout the water distribution line to facilitate closure of a particular line for maintenance work.
Different types of valves used in a water distribution system are:
Gate Valves.
Globe Valves. …
Needle Valves. …
Butterfly Valves. …
Check Valves. …
Relief Valves
*** The function of a valve is same as a tap i.e. to open or close or control flow of water. Tap has a smaller valve and is fitted just before any service utility like basin, shower etc. Valves control flow of water in larger pipe line.
TRAPS
In plumbing, a trap is a device which has a shape that uses a bending path to capture water to prevent sewer gases from entering buildings.
In domestic and commercial applications, traps are typically U, S, or J-shaped pipe located below or within a plumbing fixture.
