In terms of the DEP water supply line size table, whose key component is gallons per minute, the differences are even more dramatic. Basing calculations of an average run of pipe of 50′, an 1 1/4″ line provides 16 gallons per minute. On the other hand a 1″ line only provides 9 gallons per minute.
Can a building not be connected to the main water system?
Existing buildings, and buildings that are not connected to mains water, may have low pressure systems or unequal pressure systems (with different pressures for hot and cold water supply).
Why do you need a larger water supply line for a commercial building?
As a result the DEP sizing table, commercial properties typically require much larger water service lines than residential properties to meet code. Part of supplying water to a building is based upon pressurized water passing through the water supply line. The line itself provides resistance to the water flow.
Where are the pumping stations in a water supply system?
Main pumping stations which supply water to the distribution system will be located near the water treatment facility or a potable water storage facility and will pump directly into the piping system. These pump stations may be a part of these other structures.

How big of a water line do I need for a three family house?
In the case of a three family house an 1 1/2″ service line is typically required. Again the exception would be if the length of the run of pipe was only 35′ or less. In most cases a six family house or greater will require a 2″ water service line.Every type of plumbing fixture has an estimated gallons per minute factor.
How big is a 2 inch water supply line?
But in terms of area, the inside area of these size pipes (water supply tubing) is a difference of about 56% greater. As another example let’s compare 1 1/2″ pipe to 2″ pipe. The difference in area inside an 1 1/2″ pipe compared to a 2″ pipe is around 77%.
