Back-Flush Toilets
- POST a QUESTION or COMMENT about the history, models, brands & types of toilets & toilet flushing or operating mechanisms
Guide to back-flush toilets, usually wall-mounted such as shown in our page top photo. These wall-mounted toilets are principally of two designs: flushed using a water reservoir tank or using building water pressure with no reservoir tank.
This article series describes the different types and models of toilets: historical or old toilet types, wooden high wall-tank toilets, conventional reservoir tank toilets, low-flush toilets, water saving toilets, back-flush toilets, up-flush toilets, and even chemical toilets.

Back Flush or Rear Flush Toilets Using a Reservoir Tank
Shown here is a rear-flush toilet manufactured by Crane and installed in the Mansfield Hotel in New York City. This toilet uses a conventional water reservoir tank to accomplish toilet flushing.
A back-flush toilet is designed to flush horizontally out of the lower back of the bowl into a waste pipe that is mounted in the wall behind the unit. In comparison, a standard bottom-flush toilet is connected to a waste pipe in the floor below the unit.
In this article you'll see five variations of back-flush toilets or water closets:
- Floor-mounted back-flush toilets
- Wall-mounted back-flush toilets
- Floor or wall-mounted back-flush toilets flushed by use of a reservoir tank of water mounted atop the toilet
- Floor or wall-mounted back flush toilets flushed by use of a reservoir tank of water mounted hidden inside the wall
- Floor or wall-moutned back-flush toilets flushed by use of a flushometer valve (no reservoir cistern or tank)
A traditional back-flush toilet is designed to work by gravity alone.
A back-flush toilet that does use a reservoir tank is also produced for special situations such as a location that prohibits installing a drain line in the floor below the toilet.
At the top of this page we illustrate a back-flush toilet installed in a Two Harbors Minnesota home built in the 1960's.

Our back-flush toilet photo below illustrates a floor-mounted, reservoir-tank or cistern, back-flush toilet located in a basement of a home found in the Hudson Valley of New York.
In this basement the sewer line ran just a few inches above the basement floor.
The plumber mounted a back-flush toilet on a short concrete pedestal, raising it just enough to flush into the nearby sewer line found in the wall behind the toilet.
Back or Rear Flush Toilets, Tankless: Using Water Pressure, No Toilet Tank
Above is a photo of a modern tankless, back-flush, flush valve operated toilet installed in Molde, Norway. This toilet is also a back-flush model, sending waste out of the bowl towards the rear of the toilet and into a waste line in the building wall rather than in the floor.
The flush control for this tankless back-flush toilet is that round button just above the toilet tissue holder. It's not always obvious whether the toilet is being flushed by a reservoir or cistern hidden in the wall or by water pressure alone using a flushometer valve.
But some back-flush toilets using building water pressure and a flushometer valve like the Sloan HET (below) are easily identified by noticing the presence of a traditional flushometer valve.
Below: The Sloan HET Efficiency-Series wall-hung water closet illustrates this use of a Sloan flushometer valve to flush the toilet.
Other wall-mounted water closets (toilets) such as the DXV or the Toto Aquia® shown below use a cistern or "toilet tank" that is mounted within the wall cavity.
Modern brands of rear-flush toilets include the companies and toilet installation guides given just below.
