How to choose a corrugation for the toilet - the main
When replacing equipment, as well as when changing the position of plumbing in the bathroom raises the question of docking with the sewer system. Corrugated toilet pipe allows you to solve this problem as quickly and simply as possible, and thanks to this product the work is greatly simplified. But it is very important to choose the option that is suitable for your conditions and will last as long as possible, and this article will be devoted to this.

Advantages and disadvantages of the type of products under consideration
Consider the main advantages of corrugations:
Simplicity | Installation is very quick and easy - you can connect the toilet to the communications in just a few minutes. It does not need special tools and professional tools, the maximum that is required - sealant to improve the reliability of seals |
Budget | The price of the product is incomparable with other expenses in the repair of the bathroom. This factor is one of the most important, because even if problems arise, the node is easy to replace, and the costs will be small. For example, if you need a temporary connection, then this option will definitely be the most optimal solution among all possible |
Flexibility | Due to the fact that the design is easy to bend, you can put the toilet offset from the sewer socket or position it at an angle. In this case, no additional work is needed, everything is very simple. It is only important to control the position of the corrugations, excessive bending increases the risk of blockage and may cause a rupture of the system. |
Reliability | Corrugation for the toilet according to GOST 21485 94 must comply with the requirements of strength and durability. Of course, imported versions are manufactured according to other standards, but if you purchase domestic products, compliance with this regulatory act will indicate its high quality. |

It is worth noting some disadvantages that you should know:
- Thin plastic, from which the corrugations are made, may be damaged by impact or other deformation effects. Therefore, in the workflow is important accuracy.
- The position of the pipes should be such that no sagging is allowed, since in such places the danger of clogging is several times higher.
- Such structures can not be placed in the walls, they must be open. This is due both to their low resistance to external pressure, and to the fact that their lifespan is still small, and you will have to tear down the wall or floor if you fail.
Tip! Nowadays there are many manufacturers on the market, representing products in a wide variety of price categories. And as practice shows, most budget decisions cannot provide the necessary reliability, so you should not save on quality.

Important factors to know
Consider how to choose a corrugation for the toilet and how to carry out work to ensure maximum reliability of the system. There are a few basic nuances, and they need to be taken into account.
Types of corrugations
According to their strength indicators, products are divided into the following types:
- The soft construction is made from polypropylene raw materials and is highly flexible. It is convenient to use it as a temporary option or as a solution to the problem with a rather sharp bend. In addition, it can be used to bypass pipes and other interferences. Also, this option fits all types of release and docks with almost all communications.
- Reinforced corrugation for a 110 mm toilet bowl is much more expensive, but its service life and strength indicators are many times longer. This is achieved due to the fact that the walls are reinforced with wire, this makes them less flexible, but the resistance to tearing is much higher. Instructions for use practically does not differ from the usual soft design, but it is worth remembering that making a sharp bend is unlikely to work.

The maximum length of the structure in the stretched state can be divided into two groups:
- A short corrugation for a toilet bowl is used in places where the outlet of the sewer system is located very close. Its main purpose is to provide a strong connection with a bend, while usually strength is not so important. It is only necessary to ensure that the bend angle is not superfluous, otherwise there is a high risk that the corrugation will simply burst.
- If the distance from the toilet to the sewer pipe is significant, then you will need a construction of increased length. It is better to choose reinforced versions that will provide a rigid connection, especially if the length of the structure is large, any sags are extremely undesirable and lead to the danger of rupture.
Tip! You should not take designs of small length in the hope that they will stretch. Installing the maximum tensioned elements reduces their reliability several times.
It is worth noting another important fact - many do not know that the corrugation for the overflow cistern is a unit installed in the shut-off valves, and has nothing to do with the connection to the sewage system. In such constructions connecting elements are no different from others.

Installation recommendations
To ensure the best reliability, it is important not only to choose a quality product, but also to install it correctly, the work is done as follows:
- First of all, the release of the toilet bowl is cleaned of dust and dirt; it should be dry and clean.
- After that, either the outer part in the toilet, or the inner part in the corrugation is lubricated with silicone sealant, and the elements are connected neatly and without distortions. Then it is necessary to wait several hours to freeze the sealing compound.
- Next, the toilet is put in its place and is attached (if it is not already done).
- After the sewer socket is cleaned of dirt and moisture, a corrugation is inserted into it (a sealant is also used to ensure reliability).

- The last step is to check the system for tightness.
Conclusion
In fact, the installation work is very simple, it is important to choose the best option and not to damage it during the installation process (see also the article The mechanism of the toilet bowl cistern and its typical problems).
