Unreferenced stub auto yes date December 2009 Orphan date December 2009 In plumbing , a Fixture Unit FU is equal to one cubic foot of water drained in an 1 1 4 pipe over one minute. A Fixture Unit is not a flow rate unit but a design factor. One cubic foot of water is roughly 7.48 gallon s 6.25 Imperial Gallons A Fixture Unit is used in plumbing design for both water supply and waste water. Different fixtures have different flow requirements. In order to determine the required size of pipe, an arbitrary unit is used for pipe sizing which takes into account the likelihood that all the fixtures will not be used at the same time. This is called fixture unit FU . The relationship between gallons per minute gpm and fixture unit is not constant, but varies with the number of fixture units. For example, 1000 FU is equivalent to 220 gpm, but 2000 FU is not double that, but is only 1.5 times as much, or 330 gpm. There are situations where a design provides for more FUs being discharged than being supplied.

Orphan date December 2009 Unreferenced date December 2009 Image chicago loop plumbing 01.png thumb right 400px Chicago Loop for under cabinet waste plumbing The Chicago Loop is an alternate way of venting the Trap plumbing trap installed on an under Countertop counter island sink or other similar applications where a conventional vertical vent stack is not feasible. Function As with all drains, ventilation must be provided to allow the flowing Wastewater waste water to displace the sewer gas in the drain and then the vacuum which would otherwise form as the water flows down the pipe. A Chicago Loop provides an elegant solution when the drain is opened, water displaces the air to the tee. The water will flow down while the air is displaced upward to the vent. After the water has passed, air will be replenished through the vent. The key to a functional Chicago Loop is that the top elbow must be as close to, if not higher than, the flood level peak possible drain water level as possible. This ensures the vent will never become waterlogged. The second way provides a simpler path for the return airflow after the water has passed the drain. Cost The cost of installation is high because of the number of elbows and small pieces of pipe required with modern plastic drain pipes, the largest outlay will be labor. Street elbow s will be helpful. Alternatively, installation of an air admittance valve can be used in some cases to keep costs down. Alternately if moving sink to an island sink, install the P trap below the floor of the island and vent off the top of the drain. Attach toward the trap and reverse 180 degrees so any water in the vent flows down the drain. Slope drain down, slope vent up, and attach to existing vent from previous existing fixture that is now abandoned. Patch previously existing drain to become vent.
