1.0 gpf water closets and flush valves have been the commercial baseline for maximum flush capacity since 1992. In more recent years, the 0.5 gpf and 01.25 gpf urinals and flush valves have become more popular for LEED projects and water conservation efforts. The 0.125 gpf systems are even becoming the baselines in certain parts of the U.S. 

For commercial urinals 1.0 gpf is the maximum allowed by code and 0.125 gpf are the lowest flow flushing urinal that is available.  Water-free urinals are manufactured by various companies and are designed not to use any water after every use.  However, water free style fixtures required more daily cleaning maintenance, monthly fixture maintenance on the sealing mechanisms, and annual drain line cleaning.

A top spud fixture refers to a flush valve connection that is on top of the toilet generally located behind the seat.  A back spud fixture has a connection for the flush valve located on the back of the toilet.  In most cases a back spud fixture will use a concealed flush valve.​
A carrier is a steel fixture that goes behind the wall to hold “wall hung” fixtures off of the wall….i.e. toilet, sink, urinal and for floor mounted back outlet bowls to secure the drain assembly to the fixture.  It is required any time a wall hung fixture is specified.

Wash down urinals direct water to the water distribution box which spread water across the back wall of the urinal and it flows down cleansing the back wall.  A siphon jet urinal also utilizes this action but additionally directs water to a siphon jet located in the trap of the urinal. Siphon jet urinals typically flush at 1.0 gpf whereas wash down urinals can flush with less water and can operate on as little as 0.125 gpf.

Handicapped/elderly height (also known as ADA height) has a rim height of no more than 17 inches measured to the top of the rim.

Both terms are used interchangeably to describe the flushing mechanism of the urinal.

To be able to supply the minimum 15 gallons per minute required to properly actuate the flush valve and fixture.

Both types of flush valve are sensor-operated. Battery type flush sensor flush valves are hands-free activated units that are typically operated on alkaline or lithium type batteries. Most studies conducted can state battery life lasts between 3-4 years in most flush valves. For hardwired flush valves, these units tap into a facility's electric supply once installed. They are​ powered through transformers that can convert the electric current down to the proper amps required to activate a flush valve. There also hands free sensor operated devices.​
