ABSTRACT
The pillar tap is used to supply water to basins, baths, bidets and sinks. Combined hot and cold pillar taps are available with fixed or swivel outlet. The outlet of these taps must be bi-flow that is separate waterways for hot and cold water to prevent cross flow of water within the pipe work. Fluoridation an additive introduced to drinking water by some supply authorities. The water authority requires at least seven days' written notice for connection to their supply main. The main is drilled and tapped live with special equipment, which leaves a plug valve ready for connection to the communication pipe. The communication and supply pipe should be snaked to allow for settlement in the ground. The drain valve has several applications and is found at the lowest point in pipe systems, boilers and storage vessels. Application an on/off isolating service valve used for system and appliance maintenance.
