Tankless toilet

Modern plumbing has come a long way before appearing as we used to see it. All these installations, tankless toilet and smart appliances originate from recesses in stone walls connected to gutters. The age of the findings is 5000 years.

And in ancient Egypt, there were sand wooden boxes . Obviously, the connection to the gutter was out of the question then. But in the Roman Empire, the toilets were more comfortable. Like baths, they were public and connectes to the sewerage system, where water was periodically released. Unfortunately, with the decline of the empire, the culture of hygiene had come to naught, and before the Renaissance, the question of how to equip the toilets was of little interest.

The design of the valve float, which are still in modern models, was invented only in the early 18th century. And the tankless toilet has come into our lives relatively recently. In many people it is associated with an installation that assumes a tank, but it is hidden behind a false wall. In fact, however, it’s not the only option.

Druckspüler

There are toilet bowls that don’t have a tank as such. Instead, a system with the characteristic German name “druckspüler” is used. In translation, it means “pushpull” or “flush tap”. It takes up minimal space and is very easy to install. It can be mounted in a wall, hidden behind a partition or mounted on the outside.

How do tankless toilet work? Flushing carries out with incoming water directly from the water supply. The absence of a tank and the special cartridge with two chambers ensure a very powerful pressure.
The druckspüler looks like a wall-mounted key button or a simple external design. The casing of the unit, both in concealed and open position, is a small cylindrical element in which the riser pipe fits on one side and the drain outlet into the drain system on the other.
The only thing to consider is the presence of an adequate connection to the cold water supply, as well as the implementation of the drain pipe to the toilet.

The advantages of such a tankless toilet include compactness, ergonomics and, most importantly, economical use of water resources. In addition, there are no frequent problems with standard models with cisterns: clogs, failure of the internal water level control system, flooding the tank and others.

In addition, the MS992CUMFG#01 design uses EWATER+ or so-called antibacterial water. This is a liquid which is treated by electrolysis. In this way it becomes acidic and acquires a low PH level. The system works quite simply. Before first use, the bowl is sprayed with plain water. This is done to eliminate harmful microorganisms, because fewer bacteria are retained on wet ceramics than on dry ones. After use, the bowl is sprayed with already ionized EWATER+ water, which has a bactericidal effect. It should be noted that EWATER+ is environmentally friendly and can be returned to the natural environment without fear.

It is noteworthy that the rod material contains silicone and is antibacterial.
  • When wet, silicone repels any solid particles. Dirt and lime scale simply have no chance. This allows the retractable nozzle to be cleaned exclusively with water. For example, the device with the WASHLET system does not need to be regularly filled with nozzle cleaning compounds and maintenance is no longer necessary.
  • The toto modern toilet is equipped with an energy-saving mode if you care about the environment and budget.

Waste disposal is achieved with 3D TORNADO FLUSH, a powerful cleaning system that has “rethought” the traditional flush concept. Usually, the water flow is directed from under the rim, under which bacteria and dirt often accumulate, but in the toilets with TORNADO FLUSH it simply does not. Thus, the jets from the openings in the casing create a whirlpool effect, which eliminates impurities on the entire inner surface. The system works almost silently. It is much more pleasant and hygienic to use this device.

The 3D prefix in the title means that the toilet is additionally equipped with three nozzles, which create a strong flow of 0.9 or 1.28 gallons.
  • The design also includes a Dual-Max system. This is an extremely important component. Dual-Max determines the required amount of water to flush and turns on as soon as you move away from the toilet.
  • The universal height of MS920CEMFG#01 provides the most comfortable position for a wide range of users. It is suitable for all family members, regardless of age and gender, and helps people with disabilities and mobility to achieve self-service and independence.

Model with an advanced stretch bowl and Cyclone system. The latter is a cyclone syphon blast mechanism that uses centrifugal and gravity. Like a cyclone in the atmosphere, Cyclone technology creates a powerful whirlpool of 1.0 or 0.8 gallons. The base of the 550h toto neorest is ceramics coated with SanaGloss.

Nature’s Head NH-SPH

Nature's Head NH-SPH

Nature Head Composting is a real American product for living on the road. The manufacturer claims it is the most reliable version of a portable toilet. Their main goal was to create comfortable sanitary ware for people with mobile lifestyles. Therefore, NH-SPH can be used in harsh sea conditions, on land, and in any other place where there is no water supply (tents, workshops, sheds, buses, SUVs, trucks and even yurts).

This tankless toilet is quite light, with an elongated bowl, but it does not interfere with its installation in a narrow space. It does not spread unpleasant odours, which is very important in hiking conditions, and has an integrated fan with low volume air circulation, which helps cleaning. The toilet has a power of 0.72 W and draws out 1.7 amperes in 24 hours. A study of Nature’s Head in Alaska found that this equates to 4-5 cents per month in monetary terms.

  • Since NH-SPH was originally designed for use on board a ship, the materials used were more durable. This standard has been maintained to this day. It is resistant to corrosive processes, resistant to acids and “heavy” chemicals, easy to clean and also perfectly tolerates contrasting temperatures. But the most important thing – antivandal properties.
  • Steel is virtually impossible to deform or damage in any way.

Summing up: strengths and weaknesses

There are two types of systems . The first one is – into the wall, the second one is external. Both designs are quite compact and do not require much space. However, despite the stable position on the market and the wide range of models, tankless toilets are still unfamiliar to many people. Therefore, it is worth buying such plumbing equipment, weighing all the pros and cons in advance.

As for the pros:
  • Aesthetics. The main advantage of cowhless devices is their appearance. Such toilet always looks ergonomic and modern. It does not catch the eye and does not “weight” the interior. Even on the contrary, visually the bathroom will seem spacious and lighter.
  • Saving space. If you have a small bathroom, and for every inch you have to fight, choose a cowhless device with a wall type of installation, the construction without a “foot” takes up a minimum of space.
  • Hygienic. Cleaning in a room without a bulky cistern is much easier and faster.
However, there are toiletless problems and weaknesses:
  • Installation. Of course, everything depends on the model you choose. If it’s a mobile toilet for trailers and camping, there’s no problem. But the ultra-fashionable hinged plumbing requires quite complex installation work.
  • The price. Standard models with a cistern, as a rule, are cheaper. The same situation with repair and maintenance. In addition, if the wall model breaks, you will have to destroy the finish, and then spend money not to restore it.
  • The condition of the water supply system. If the fixture works with the help of a system of drukshpuler, it is necessary to have a good water pressure. Sometimes city apartments may not have enough pressure, especially during the warm season.

Choice issue

Give yourself clear answers to the following questions before you go shopping for a tankless toilet:

  • The toilet from what material will suit you in terms of properties and cost. It can be stone, porcelain, faience, metal or plastic. The most popular option – porcelain and faience, the most original – stone, the strongest – metal, the most budget – plastic.
  • What shape of the bowl is convenient for you: round, oval, rectangular, square, semi-circular, elongated. The latter is considered the most comfortable, so most manufacturers emphasize on this form.
  • Which way of release is optimal for your apartment or house: vertical, horizontal, oblique, vario (double). Universal are oblique and vario.
  • Bathroom equipment with what type of installation you need: tankless floor mounted toilet, wall, corner, attachments or mobile. If the toilet is fixed to the capital wall, a block type installation is suitable. If the weight is on the floor, you will need a frame type installation. It has a reinforced structure, – which is additionally attached to the wall.
  • Where exactly will the fixture be located? The standard location – you can buy any type of installation, on an island – you will need systems no higher than 32 inches, in a corner – use a simple or find a special installation designed for corner toilets.
Additional functions should also be considered:
  • The bidet function. Some models are already combined with a bidet, which greatly simplifies the care of intimate parts of the body, while others require the installation of a bidet cover. The most advanced devices have an electronic control panel, which allows you to regulate the force of the head, direction, angle of water supply, temperature, power of the hair dryer, etc..
  • Hygienic shower. It is a short hose with a miniature handshake. It performs the same task as a bidet, but it does not require any special conditions for installation, does not take much space and is cheaper. Such a toilet shower can be fitted initially, but nothing will prevent you from fitting it later.
more
  • Prevention of flooding. This function is activated when the tank is full of water. It activates the automatic drain system.
  • “Anti-splash.” Instruments with this function have a narrow funnel-shaped bowl that prevents splashing. In addition, the drain hole in them is arranged asymmetrically. This design is found in many models and has almost no impact on cost.
  • Without a bezel. Such a toilet is virtually the same on the outside as the standard version. Feature is a small change that affects the flow of water at the time of drainage – the lack of bezel, which distributes the liquid around the perimeter of the bowl. However, the bezel has a negative impact – under it dirt accumulates and bacteria multiply. The rimless design solves this problem radically: no rim – no hidden areas. Some models are also equipped with a breaker that divides the jet into several directions.
  • Double drain button. With this button you will control the water flow. Drainage can be small or full. With this mode, you will save 20-25 cubic meters of water per year.

It would be a good idea to study producer policy and read the tankless toilet reviews. German, American, Japanese firms have managed to earn a good reputation. Chinese companies can boast of a wide range of products, but the quality of sanitary ware from the Celestial Empire is not always good. Some manufacturers in order to save money carry out firing ceramics on accelerated technology, which suffers from the strength of the material.
Having an idea of what type of WC will fit into your interior, you will easily make the right choice.
