    A plumbing fixture is defined as any device which requires domestic water. Washing machines, urinals, sinks and showers are examples of plumbing fixtures. Take a look at the flow calculation sheet in Figure (page 4). Notice that each type of plumbing fixture has been assigned a fixture unit count in column A. model plumbing code that will be used to size the water softener. 3. Plumbing codes account for water demand by assigning water supply fixture units (wsfu) to each water appliance. Using the first table on the page, find the wsfu rating for each water fixture in the house (to be located downstream from the water softener). Add theseFile Size: KB.

This online engineering PDH course provides basic design criteria pertinent to the design of plumbing systems. This course may be used for conceptual design in the absence of any more appropriate information. This course identifies and outlines the types of drainage systems (sanitary and storm water), effluent disposal, supply water distribution systems and hot water systems, appropriate for.

    The Basics of Pipe Sizing. Before you begin, to perform pipe sizing for a plumbing system, you need to have a good set of families that have either flow rates or fixture unit ratings applied to the piping connectors. A good set of families are the building blocks of good pipe sizing results. Created Date: 3/25/ PM.

Water Supply Fixture Units. Private Installations. Public Installations. DFU (Drainage Fixture Unit Values) is defined by the the Uniform Plumbing Code (UPC) and can be used to determine required drainage capacities from fixtures and their service systems.

A Fixture Unit is not a flow rate unit but a design factor based on the rate. Created by the American Society of Plumbing Engineers (ASPE), the Plumbing Engineering & Design Tables App offers in one convenient place all of the equations, pipe sizing data, and background information that you need to successfully complete plumbing system design and installation projects on a daily basis.

The app includes applicable data and information from the major plumbing codes and /5(). In plumbing, a Fixture Unit (FU) is 'a unit of measure, based on the rate of discharge, time of operation and frequency of use of a fixture, that expresses the hydraulic load imposed by that fixture on the sanitary plumbing installation.' A Fixture Unit is not a flow rate unit but a design factor.

A fixture unit is equal to one cubic foot of water drained in an 1 1/4 pipe over one minute. This National Plumbing & HVAC Estimator is a guide to estimating labor and material costs for plumbing, heating, ventilating and air conditioning systems in residential, commercial and industrial buildings.

A water supply fixture unit is a numerical load factor used to compare the relative load-producing effects of one type of fixture to another type of fixture. When the concept of water supply fixture units was originally developed in Methods of Estimating Loads in Plumbing Systems (BMS65), an advanced method of probability and a select.
