Which toilet bowl edition to choose?

When arranging a bathroom, the owner has no more important task than choosing a toilet. This is especially perplexed by the person who built his own house, and now solves the issues of sewage and what is connected with it. The choice of the release of the toilet directly depends on the scheme of the device of the sewerage system of the structure.

The toilet bowl as a whole is a plumbing device, consisting of two main elements:

• a bowl that performs the functions of collecting and removing human waste products;
• a drain tank, which ensures the accumulation and preservation of a supply of flushing water.

Toilet bowls, depending on the device of the outlet, are divided into three types: with horizontal (straight), vertical and oblique (angular) outlet. The most popular in the Russian Federation are the toilet bowls of the last of the listed types - with an oblique outlet.

According to the current requirements for standard designs of sewerage systems in residential buildings and office buildings, except for toilets with oblique outlet, no other types of them can be connected to the sewerage system. This becomes possible only if the sewer pipes are moved to the appropriate position. But this work is not justified by any considerations.

• Horizontal release, located parallel to the floor, assumes connection to a sewer riser located at the same level with it. It has significant disadvantages: it is difficult to install the bowl in cases of even the slightest discrepancy between the outlet pipe and the adapter on the sewer pipe, frequent blockages of the exhaust system due to the rectangular elbow at the junction with the sewer, leaks often appear at the joints with the sewer. But since toilets have an aesthetic appearance, they are increasingly found in modern high-rise buildings and private sector houses.
• Often used in private construction vertical exhaust system... Its outlet is directed vertically downward to the floor. The outlet of the branch pipe is usually arranged directly under the bowl, therefore it is also called the lower outlet. The vertical outlet is available in a rear and lateral version. For such toilets, a sewage system is required, carried out in a special way, under floor slabs or under the floor. This type of toilets uses flush water more economically, but is inconvenient for installation, detection and elimination of leaks. It is also found in old buildings (for example, in "Khrushchevs").

• Oblique release has an inclination towards the floor from 30 to 45 degrees, it is easy to connect it to the sewer collector, which can be at an angle from 0 to 40 degrees with respect to the outlet of the bowl. That is, it does not matter if the sewer collector runs along the wall directly at the floor level or is fixed at some distance from it.

Manufacturers of modern plumbing equipment offer toilet models with any release systems. Among elite products, the decisive factor in the choice is operational comfort.

For most buyers of popular models of plumbing, the following features remain the main indicators in the choice:

• cleanliness of bowl rinsing;
• seating comfort;
• lack of unpleasant odors from the sewage system;
• no splashes during direct use and flushing;

• minimal noise when collecting water into the tank and flushing;
• the possibility of clogging the release device;
• convenience of repair work.

It should be noted right away that the type of release does not in any way affect the cleanliness of the flush, the feeling of comfort from sitting on the toilet, the presence of a smell in the toilet, etc. All of the above is more influenced by the shape of the bowl and the flush device.

In funnel-shaped bowls, made from the inside in the form of a funnel with a drain hole in the middle, the flush is the most hygienic. Sewage, even without flushing, immediately falls into the water, which is "on duty" in the drain hole, performing the function of a water seal. The water trap serves as an obstacle to the penetration of unpleasant odors into the toilet room from the side of the sewer lines. But there is a downside to the ingress of sewage directly into the water - the unwanted formation of splashes. A lot of splashes are also generated during flushing.

Models with a slope towards the back or front side of the bowl are called roof toilets. In them, just as in funnel-shaped structures, the contents do not linger and are easily washed off. Spatter formation during flushing is negligible. Visor models are considered the best solution for the shape of the bowl.

There is another design of the bowl, the drain hole in which is located at the front wall, and the rest of the inner part is a solid horizontal shelf (plate) of a slightly concave shape.

This model of toilet bowls is called a poppet and is now outdated, unable to withstand the competition due to the following shortcomings:

• the presence of feces on the shelf before they were washed off contributed to the spread of unpleasant odors throughout the apartment;
• water constantly stood in the concave part of the shelf, which led to the formation of rusty or dirty spots on it;
• frequent cleaning of the bowl from deposits and rust on the shelf.
• After almost every flush, it was required to additionally use a brush for cleanliness (in previous models, they are used occasionally).

If you study the plumbing feedback forums for a long time, the advice of toilet specialists and stories about your experiences of ordinary consumers, then, in the end, you can make a choice. And whether it will be correct will be shown by our own experience. But it is better to learn from the mistakes of others and sometimes listen to the practical advice of the masters.

Waste removal takes place through the bowl release device. An outlet is a system that ensures the passage of flush water with all its contents from the bowl to the sewer line.

Here are the opinions of their owners about toilet release systems.

• Vertical release. It is good for everyone, but for most consumers it is either not suitable because of the layout of the sewerage system, or because of the high cost of installation and repair services, as well as the cost of the plumbing itself. But experts strongly recommend such a design for a private cottage: the device can be installed almost anywhere that is convenient for the owners. In addition, the sewer main will be hidden under the floor, in the basement, and therefore will always be under control and convenient for repair work.
• The horizontal release is considered universal. It can be connected to a sewage system, designed not only for toilets of just such a design, but also for corner devices (oblique outlet). True, as noted in the reviews, this does not always work, mostly in cases where the sewage system runs at floor level. To do this, you need to adapt the corrugated adapters and even remount the sewer bell.

This raises the question: why seek difficulties for yourself? Toilet bowls of any modification are produced for all release devices in large quantities.

• Oblique release. He has no equal in popularity yet. In the retail network, this type of toilet bowls dominates.If calculated in percentage terms, then the departments of plumbing stores, representing the equipment of the bathrooms, consist of 70% of products with an oblique release.

Surprisingly, some consumers call this type of toilet bowl universal. Their outlet can be connected to the sewer, which is located both on the floor and in a hanging position at some distance from the floor.

In general, when choosing equipment for a bathroom in a typical high-rise building, it is best to focus on the release provided for by the existing sewage system, and for private construction - on your own plans. And there is no need to reinvent the wheel where it already exists.

Whatever the experts and experts advise, the final choice of the toilet rests with the owner. Dealing with sewer communications and the type of toilet release suitable for them is not a problem for the inhabitants of high-rise buildings. A matter of a few minutes.

A more difficult task for a private developer, but he can also decide in a day or two on the graduation system of the future "needy". Recently, the vertical version of the outlet pipe has been gaining popularity among such buyers.

The reasons for this choice are often the following criteria:

• almost silent flush;
• the efficiency of the device in terms of water consumption (it is these models that consume it least for flushing);
• the type of toilet bowl without external pipes of the exhaust system is preferable for any owner;
• such a toilet without unnecessary external devices takes up a minimum of space in the toilet room (especially valuable for small toilets).

But there is no need to rush here either. In addition to the advantages of this design, there are also disadvantages.

Let's consider the main ones.

• The choice of models among the assortment of goods for toilets offered in Russia is relatively small.
• The high cost of such equipment.
• Problems of installation, replacement, dismantling and leak detection (this applies only to typical apartment buildings). The toilet bowl for apartments of typical buildings must definitely correspond to the one for which the sewerage system was created. For example, if the sewage system was installed with the expectation of a horizontal outlet system for a bathroom, then a bowl is purchased with a horizontal outlet.

But for choosing a specific model, there is a much wider range of features and parameters that the buyer should pay attention to.

Here are the most basic ones:

• ease of use by all family members, including children and the elderly;
• the dimensions correspond to the room;
• clean flush without splashing (with anti-splash system);
• dual-mode flush is more economical;
• the price is not to the detriment of the family budget;
• ease of maintenance and use of the device;
• material (porcelain, earthenware is the best choice):
• installation type (suspended, floor standing, compact, built-in tank).

There are general guidelines for connecting the toilet to the drain. These rules do not depend on the type of exhaust system of the device, on its functionality and even on the material of the sewer network.

They are expressed by the following principles:

• The outlet must correspond to the accepted sewer pipe scheme specifically for the selected model.
• Using various devices (adapters, cuffs, corrugated bends) to connect the outlet to the sewer system, it must be taken into account that their diameter in the section from the bowl to the collector should in no case be less than the diameter of the outlet.

• Branch pipes should have a slight slope towards the sewerage system (2 cm / running m for a pipeline with a standard diameter of 110 mm). Moreover, such a pipeline must be fastened every meter so that it does not sag over time.
• All connections on the site must be sealed.Remember that in the sewage system there is not only waste water, but also gases that can enter the room through any leaks in the system.
• When installing the drain from the toilet, do not allow sharp turns of 90 degrees. It is better to do with two 45-degree bends (there are such mounting tees) than to clean the blockages later.

Experts advise to choose:

• porcelain models that have a long service life and do not lose their attractive appearance;
• a funnel-shaped or visor bowl with a bevel towards the back wall;
• of the two types of flush, give preference to a circular one, washing the bowl from all sides in a circle;
• vertical exhaust system in case of private construction.

Everything else (type of attachment of the bowl, cistern, color and design) should be entrusted to your own taste and preferences. In some ways, you can ask the professionals for advice, but where you cannot do without your own impressions, the decision for the choice must be made independently.
