What is the standard faucet supply line?
The two most common are 3/8- and 1/2-inch compression or male pipe thread.

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%.

How is the size of a water line related to the pressure?
A water supply pipe of a given size can only supply a given quantity of water at a given pressure and a given hydrostatic head. Hydrostatic head commonly refers to the vertical distance a water line extends. This short video is fantastic. Pay attention to the first two numbers he quotes!!!
How big is a DEP water supply line?
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.

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.
