Types of corrugations

How to install the corrugation on the toilet Types of corrugations for the toilet bowl

In fact, there are quite a few types of corrugations for the toilet, but people do not always get what they need, because they do not even know about the possibility of choice. In the photo you can see the corrugations, which differ in the shape and method of connection. They differ in characteristics that you need to know.

  • Although the corrugation stretches like an accordion, it is still important to take into account that there are limitations. When choosing, find out what is the maximum length of the pipe in the stretched state.
  • Corrugation can be both hard and soft. The rigid pipe is more resistant to wear and mechanical damage, but it will not always be able to bend as desired. When choosing a product, this factor should be taken into account.
  • The stiffness of the corrugations is influenced not only by the thickness of the material from which it is made, but also by reinforcement. Springy thin wire increases the rigidity of the structure and prolongs its service life. The flexibility of such a pipe is very slight.

The nuances of using the corrugated pipe

The use of the corrugated pipe greatly facilitated the installation of the toilet bowl, especially when it needs to be shifted or unfolded. But it is important to remember that this is not a panacea, and this type of connection, besides the advantages, has its drawbacks.


  • For the installation of the corrugations do not need to have any special knowledge and skills. It is enough to familiarize yourself with the instructions described in the article, and the work can be done independently.
  • Replacing the corrugations of the toilet bowl is easy to do with your own hands.
  • In some cases, this plumbing fixture can only be connected with a corrugated pipe.


  • A soft tube has low strength - it can be accidentally pierced with a sharp object.
  • Some chemicals react with the material from which the pipe is made, so its walls can gradually become thinner. Plastic will be deformed if you pour boiling water into the toilet. It is fair to say that the faience product may burst when in contact with boiling water.
  • The life of a corrugated pipe for a toilet bowl is small, so an untimely replacement can lead to leaks, but considering how much a corrugation costs and the simplicity of its replacement, this drawback can be considered insignificant.
  • If the corrugation is visible, the exterior of the room may not be very attractive. This problem is solved by installing the box, which leads to additional costs.
  • A strongly stretched corrugation will sag, which will lead to an accelerated clogging of the pipeline in this place. In this case, you have to figure out how to support it.
  • The disadvantage of any corrugated pipe (used for drainage of sewage) is that the ridge surface does not pass garbage well. Therefore, in comparison with an ordinary smooth-walled plastic pipe, this pipe will clog more often.
  • There is a high probability of acquiring a low quality fake.

After reviewing the information provided, as well as weighing all the pros and cons, you can proceed to the installation.
