May be used either for the collection of water without consideration of pressure, or for storing water under air pressure or under a static Head for future distribution by pneumatic or gravity means.
Tanks
Materials used in Tanks
Stainless steel
Galvanized iron (G.I.)
Reinforced concrete
Polyvinyl chloride (PVC)
3-ways of water distribution
Upfeed system
Pneumatic tank
Downfeed system
from normal water pressure from public water main for low rise buildings.
Upfeed system
from air pressure from suction tank for tall buildings which cannot be reached by normal water pressure.
Pneumatic tank
by gravity from ovehead tanks and are supported either by structural frames or on the roof decks. Fixtures are below the gravity tank.
Downfeed tank
Pipe materials
GI pipe (Galvanized iron)
uPVC (Polyvinyl chloride)
PPR (Polypropylene random)
PB (polybutylene)
PE (polyethylene)
Include the equipment required for the joining of the various lengths of pipe, such as couplings for connections in a straight line, elbows for connections at 90° or 45°; Tees for 45° or 90° branches from one side, and crosses for 90° branches opposite each other
Pipe fittings
This is one of the essential requirements a
domestic hot water system. It should be strong to resist the high pressure of boiling water stored in it.
Hot water tank
small hot water tank. It is made of galvanized sheet, steel or copper, built into cylinder shape with concave ends either welded or riveted. The range boiler varies in size from 0.30 to 0.60 meter in diameter with a length of not more than 1.80 meters.
