In Wall toilet flush tank systems, usually for wall-mounted toilets, are described here.

Page top sketch: the in-wall tank for a Toto DuoFit concealed flush tank toilet, cited & discussed below on this page.

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.

Here we explain how to diagnose and repair problems with toilets, leaks, flushes, odors, noises, running and wasted water.

Toilet Water Flush Tank In-Wall Tank Systems, Cistern Concealed in Wall

These toilet designs use an in wall flush tank or cistern that is concealed in the building wall above and usually behind the toilet, as we illustrate below with this toilet installed in a Venice, Italy apartment, photo taken by the author in 2017.

While the Venetian toilet above is supplied with flush water from a tank concealed in the bathroom wall (notice the flush control panel in the white area above the toilet), other modern toilets combine a wall-mounted back-flush toilet with a flush tank also concealed in the wall.

For an example installation and owner's manual for in wall tank system toilets see this Toto wall mount toilet that uses a concealed in-wall flush tank.

This Toto toilet drains into the wall to right, left, or straight down.

  Excerpt:
  Installation of in-wall tank is much easier and nicelooking comparative to that of traditional tank. Meanwhile, the space layout will be more reasonable due to the application of in-wall tank pipes and connectors.
  
  The most remarkable advantage of in-wall tank is that the installation will never be limited to certain area, and can be installed wherever as you wish, which will make the bathroom layout more reasonable and nicelooking, and make good use of every inch of the bathroom space.
