What size water supply line do I need?
In most cases, the main pipeline from the street to your home is either 3/4 or 1 inch in diameter, supply branches use 3/4-inch-diameter pipe, and pipes for individual components are 1/2 inch. Remember that water pressure decreases by a half-pound per square inch for every foot pipes extend above your water supply.
How far can you run a 1 inch water line?
400 feet is too long for a 1″ pipe in most cases. I would increase it to 1 1/2″ or even 2″ to avoid the pressure loss caused by that distance. At that size, PVC is about the mose economical and if installed properly will give few problems.
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 big should a 700 foot water line be?
Fixture unit count for sizing a 700 foot water service. For a 3 bath home, 1″ meter with 1.5″ pipe. Most standard three bath homes will need 34 fixture units. Taken from the UPC code book for medium pressure sizing chart. Terry, that is some great detail.
How to size water supply service and distribution lines?
Sizing water supply service and distribution lines based on Water Supply Fixture Units (WSFU) Supply pressure 30 – 45 psi Supply pressure 45 – 60 psi Supply pressure over 60 psi
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.

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.
