FLUSHOMETER TOILETS & URINALS- CONTENTS: description of flushometer operated toilets & urinals: flushed by a flushometer valve and operated by building water pressure these toilets & urinals operate without a cistern or reservoir tank of flush water.
Here we also describe WATERLESS URINALS that do not have a flushometer valve and that use no flush water at all.
This article describes flushometer type valve operated toilets and urinals and also waterless urinal operation that use no flush valve and no water. The flushometer valve, operated by building water pressure, eliminates the requirement for a cistern or flush tank to operate the toilet or urinal.
Our page top photo illustrates a flushmate type valve-operated toilet installed in the Cafe Rouge restaurant bar in London England. All of the flush valve components and piping are hidden behind the tiled bathroom wall, showing only a lever type flush handle. Without access into the wall we can't say quite how this toilet operates nor if it uses a cistern (I think it does).
Tankless flush-o-meter valve toilets, in widespread use in North America since the 1920's, and unlike tank reservoir toilets, do not include a reservoir tank of water. At below left is a traditional lever-operated Sloan™ type Flushometer valve installed in a private home in New York. At below right we illustrate an infra-red-operated toilet flushometer valve installed in toilets in Google's New York City offices.
The flushometer valve is particularly suitable to public restrooms since there is no delay between toilet uses waiting for a reservoir tank to refill. Typical flush volume is 1.6 gallons.
Flush valve or flushometer type toilets rely instead on high water pressure, usually but not always from municipal water systems, along with a larger diameter water supply pipe, to clean the bowl and dispose of waste.
Invented by William Sloan in 1906, this valve type is still referred to as a "sloan valve" by some plumbers.
Unlike the electric flush toilets shown above a flushometer toilet or urinal relies on building water pressure and flow rate to clean the bowl and move waste past the trap into the building drain.
An auxiliary pump is not normally used.
Flushometer valves shown here are manual, operated by a push lever.
As most readers will have encountered, other flushometer valves are "touchless" and operate automatically after the fixture is used, relying on an infrared sensor to detect the presence or absence of a user.
Details about how fluhometer valves work, their required working water pressure and other features are
at FLUSHOMETER VALVES for TOILETS URINALS where we provide information about how flushometer valves work, are installed, adjusted, or repaired.
Flushometer Water Type Urinal compared with Cistern Driven Urinals & Waterless Urinals
A conventional flushometer valve water operated urinal is illustrated at below left.
In the photograph at below right we illustrate an older style urinal that uses a wall-mounted cistern to provide bowl cleansing or flush water at adequate pressure and volume. Urinal and its wall cistern are installed in a toilet in Akaroa, Canerbury, New Zealand.
At left we illustrate a dry or waterless urinal. This fixture uses a combination of bowl design, patented fixture drain traps, a trap sealing liquid, and a urine-resistant coating to eliminate the need for any flush water at all - providing a "dry urinal".
How waterless urinals work
Waterless urinals work to drain urine without creating an odor problem by a combination of features including
A patented liquid seal-trap that seals waste liquids,
Air seal trap is provided on some fixtures as well, minimizing possible return of urine odor from the fixture.
Waterless urinal models also include a liquid sealant that floats on top of the urine layer in the fixture trap to improve odor control. Typically the liquid sealant lasts for over a thousand uses of the fixture.
Manufacturers also provide a special cleaner for the waterless urinal.
