How are fixture units used to estimate demand?
The use of such fixture units can be applied to a single basic probability curve (or table), found in the various sizing methods [Table E103.3 (3)]. The fixture units are then converted into gallons per minute (L/m) flow rate for estimating demand.
How big is a drain Fixture Unit DFU?
Drain Fixture Unit, or DFU, is a plumbing design factor, or a relative measure of the drain wastewater flow or load for various plumbing fixtures. Here are two quantitaive measures of DFUs: 1 DFU = 1 cubic foot of water drained through a 1 1/4″ diameter pipe in one minute. 1 DFU ≈ (approximately) 7.48 US GPM or ≈ 0.47 liters/second
How to size a water supply fixture system?
Three Steps to Sizing Plumbing Piping Systems. 1 Add up the total number of water supply fixture units (wsfu) required in the facility. 2 Estimate demand using the table from the IPC that correlates wsfu to expected demand. 3 Size the pipe using demand vs. friction loss curves found in the IPC charts.
How to determine the number of fixture units?
First, insert the number of each type of fixture on your premises under the column headed “Quantity”. Second, multiply the quantity by the number of fixture units given under either column “Private Use” or “Public Use”, whichever is applicable. Third, post the result in the “Total column”.

What is the minimum supply branch pipe size?
The listed minimum supply branch pipe sizes for individual fixtures are the nominal (ID) pipe size. Reduced fixture unit loading for additional hosebibbs is to be used where sizing total building demand and for pipe sizing where more than one hose bibb is supplied by a segment of water distribution pipe.
