WATER SYSTEMS
Water supply to a structure begins at a water meter for public systems or from a water storage tank
for private well systems The water supply to the home or business, known as the main line, is generally 1’ plastic pipe This size may vary in relationship to the service needed The plastic main line joins a copper line within a few feet of the structure The rest of the water system piping is usually copper pipe, although plastic pipe is increasing in popularity for cold water applications
Cold water pipes should be insulated and covered with a vapor barrier to prevent surface
condensation and heat flow into the water from the warmer surrounding air Hot water pipes should
be insulated against heat loss and should be no closer than 6’ to parallel cold water pipes
If water is supplied at 50 psi, up-feet distribution is feasible for low-rise building up to 6 stories in
height For taller buildings, or where the water service pressure is insufficient to maintain adequate fixture service, water is pumped up to an elevated or rooftop storage bank for gravity downfeet Part
of this water is often used as a reserve system for fire protection systems
Hot water is supplied by gas-fired or electric heaters and circulated in tall buildings by the natural
rising action of hot water In long, low buildings, pumps are required for hot water circulation and distribution Hot water storage tanks may be required for large installations, and widespread fixture groupings For safety, pressure relief valves are required for all water heaters
