Reliable articulation of the toilet with the sewer pipe will save you from many unpleasant moments, such as seepage, unpleasant odor and pollution of the toilet room floor. But what to do when the output of the plumbing knee does not coincide with the pipe inlet, and ordinary eccentrics or extension cords cannot solve the problem? In this case, universal connecting corrugations will come to the rescue.
What is corrugation for the toilet?
The overflow class fittings, to which the corrugation belongs, is a transition device from the toilet to the sewer, which has the strength and the ability to stretch. In shape, it looks like an accordion, made of polymers such as polyethylene, polypropylene or polyurethane. The product has persistent properties to maintain its integrity under conditions of stretching, heating within acceptable limits.
Despite the apparent fragility, the corrugation is a fairly robust piece. This is due to the presence of stiffeners, due to which it can be stretched. Corrugations come in different sizes and allow plumbing articulation, even if the entrance plane of the sewer channel is rotated 90, and sometimes 180 degrees from the toilet drain outlet. The only condition for obtaining large bends of the connector is to prevent it from sagging significantly.
Application cases
There are several cases when the connection of the toilet with a corrugation is advisable or another option is completely excluded:
- The difference between the outlets of the bowl and the connecting socket of the sewer. This is due to the presence on the market of so many toilet models with their own design features. Standard connectors may not be suitable for this, but with the help of the sleeve, due to its flexibility, the issue is completely solved.
- The position of the toilet has a known proportion of displacement relative to the sewer outlet. This refers to the case where it is impossible to manage with an ordinary eccentric. The reasons for the mismatch may be different, but if this happened - the corrugation for the toilet is an indispensable material.
- The toilet is connected temporarily, it sometimes needs to be moved aside, for example, due to repairs in the toilet room. A flexible adapter will help to be able to use plumbing and not disconnect it periodically.
Types of corrugations
There are various product modifications on the market for convenient operation with all types of toilets. Spillway fittings may be:
- Small and large sizes, ranging from 21 to 50 centimeters.
- The product is a soft structure made of plastic without the use of reinforcement, with thin walls. They are more flexible, they allow you to place the corrugations for the toilet in any desired position, but they have low strength.
- Reinforced connector, inside the walls of which there is a fiber or mesh frame made of stainless wire. A more rigid design allows you to vary in a smaller range of deviations of the joints, but it is a reliable product that is very durable and, as a rule, sags less.
- With a different angle of removal of the socket, facilitating the installation of the toilet bowl with corrugation. So, along with straight sockets, there are models of sleeves in which he leaves at an angle of 45 degrees and even 90 degrees.
Corrugation device, dimensions
The technical solution of the corrugations is very simple, despite the versatility of the products. They consist of the following basic elements:
- A bell in which the outlet of the toilet seat is inserted.
- Corrugated section, with the ability to extend and due to which the connecting element has flexibility.
- A pipe inserted into the socket of a sewer pipe.
- Sealing gums, acting as sealing elements, filling the space between the connector and plumbing.
The first three elements are a single whole - a product made of plastic. Sealing gums are removable, they can be replaced if necessary. Sometimes, instead of sealing rubber elements, plastic fixed seals are provided in the sleeve itself. Such connectors are extremely unreliable and in some cases do not allow a tight joint to be obtained.
The size of the corrugations for the toilet in the technical specifications is indicated for their compressed state. So, for example, a length of 21.2 centimeters indicates that the connecting sleeve can be easily stretched to 32 centimeters. Buying a product with a size of 28.5 centimeters, you can count on the maximum length of half a meter. But when choosing a connector for a specific task, it must be borne in mind that the articulation in tension can lead to difficulties in reliable and tight fixation, as well as slipping during operation.
How to install corrugation on the toilet?
Corrugation is one of those few elements that in some cases can be installed without unscrewing the toilet from the floor. This is convenient if it is not possible to unscrew the fixing screws for the plumbing legs. The connection is carried out in the following order:
- A sealant layer is applied to the toilet pipe at the place of putting on the sleeve.
- Pull the bell of a flexible sleeve on the drain outlet of the toilet and give time to harden the sealant.
- Apply a layer of sealant to the outer wall around the circumference of the socket of the sewer pipe.
- Insert the connector pipe into the sewer and allow time for the sealant to solidify.
- The toilet is attached to the floor and the corrugation is laid out so that it does not sag, if necessary, placing supports under it in the form of bars and similar elements.
- Several buckets of water are poured into the toilet and checked for leaks from the joints.
Conclusion
Naturally, when installing a toilet corrugation on plumbing, which is not new, all pipes and sockets must be thoroughly cleaned of dirt and deposits, and sealant should be applied only on a dry surface. Of course, it is always better to invite a professional locksmith who will install the equipment with high quality and give a guarantee for his work.
