Some 20 years ago, the installation or replacement of the toilet was considered a difficult and difficult process, since it was necessary to adjust its release to the sewer. Heavy cast iron pipes prevented quick installation. Installation could be delayed for a whole day. With the use of plastic plumbing fixtures, everything was noticeably easier. Corrugated universal connectors are used for it. But how do you replace the toilet corrugations with your own hands? Step-by-step instructions and features of the work - further in our article.
Signs of replacement
When do you need to perform this operation? Do-it-yourself toilet seat corrugation is replaced in several cases.
- With axial displacement. So, the installation of the toilet is performed with axial displacement relative to the socket. This usually happens if a new tile was laid on top of the old one (because of this, the toilet bowl rose).
- If the toilet outlet is not suitable. This happens if you do not pay attention to the type of drain outlet during the purchase. For example, imported toilets may have a horizontal outlet. But Soviet apartments are intended for oblique release.
Experts advise when repairing to immediately carry out the withdrawal of pipes for a specific type of toilet discharge.
rules
The main feature of the corrugation is its flexibility, due to which ease of installation is achieved. But do not forget about some of the rules when installing or replacing the corrugations on the toilet with your own hands. Always consider the angle of release. He can be:
In case this is a direct or oblique conclusion, it will not be difficult to install the corrugation. In the case of a vertical slope, the neck of the toilet must be rigidly connected to the vertical drainage system. Otherwise, it will not be possible to establish a free drain of water. Therefore, many refuse to vertical release. In other cases, it is quite possible to replace the corrugation on the toilet yourself.
Installation step by step
Consider the procedure for connecting the toilet with the corrugation. This work is quite simple, but there is no need to disrupt the procedure. It is advisable to carry out the installation of the corrugation when the toilet is not yet connected in place. This is more comfortable. But in the case of installing the corrugation on the old toilet bowl, you will have to prepare it:
- remove old cement;
- clean from sealant (if any);
- clean the socket of the sewer pipe.
Otherwise, the tightness of the connection will be in question. Some use corrugator when installing corrugations. However, experts do not recommend using cheap, since over time it can collapse.
So, we bought a toilet. What's next? Further work is performed step by step.
- The end of the pipe is treated with silicone, which will be connected to the sewer. The end of the release is evenly blocked by a tap of 5-6 centimeters.
- The stretch is performed without distortions, as evenly as possible.
- To facilitate pulling, lubricate the rubber seal on the socket with soap.
- The corrugated pipe is installed in the inlet at one end, and the second is mounted to the toilet.
- Water is poured into the toilet.
- Check the joints for leaks.
- The points of attachment of the toilet are marked on the floor. Pre corrugation is disconnected.
- The holes are drilled and lubricated with sealant.
- The toilet is mounted on the floor. The fixing bolts are tightened until the structure ceases to stagger and is perpendicular to the floor.
- Then the adapter is reconnected.
- Joints are treated with plumbing sealant.
- Screed is poured.
- Finishing the floor surface.
Features of dismantling the old corrugation
The dismantling process will be easier if the corrugated pipe (old) is maximally stretched. In this case, it is enough to pull the pipe from the toilet nozzle, and then remove the second end from the sewer. Residues of water can be easily removed - they easily merge into the sewer.
If the toilet is located in a corner, you need to apply the arc rule. In this case, the structure is easily removed from the two nozzles, but first the corrugation is removed from the toilet nozzle.
Sometimes it happens that the corrugated pipe is not stretched at all. This happens if the toilet is located too close to the drain. To dismantle here you have to remove the toilet itself. The corrugation is then removed in the same sequence as described previously: first the end that is connected to the toilet, and then the one that goes to the sewer.
Replacing the corrugation on the toilet without removing the toilet
Over time, you have to replace this item. You can do this yourself, even if the toilet is displaced relative to the sewer. But you need to know the exact size of the adapter. He can be:
The choice of adapter will affect its life. So, how do you replace the corrugation on the toilet with your own hands without removing the toilet?
The plumbing parts are cleaned from the old sealant. The edge of the pipe is inserted into the neck of the toilet until it stops. The second end is put on the drainage system. A large amount of water is poured into the toilet. The tightness of the connections is checked.
Now it’s clear how to replace the corrugation on the toilet. Please note that if the outlet of the sewer pipe is in the floor, you need to choose a corrugation with a bell curved at a right angle. For plumbing with a horizontal outlet, a pipe with a 90 degree rotation of the bell is used.
Need to know
Thanks to the corrugation, a very significant displacement can be compensated, up to 20 centimeters. Also, the pipe can be deployed at any angle. For this, a serial connection of two pipes is used. But you need to understand that with a large pinch, a high-quality drain will not be ensured. In addition, the pipe may crack at the pinch point. This may not be noticeable immediately, but the smell will not be pleasant. This must be taken into account when replacing the corrugation on the toilet. Also, before use, the toilet is always flooded to the top to check for leaks.
What can be the disadvantages of the corrugation?
Before installing such an element, you need to understand that there are also disadvantages. Corrugation has several disadvantages:
- Too thin wall. It can be damaged easily inside and out. If you accidentally flush a glass fragment into the toilet, you can break through the corrugation. Yes, the material may be in an aggressive environment, but it is unstable to mechanical damage.
- Aesthetics. Outwardly corrugated pipe does not look as neat as a plastic one. In addition, on many models the wall may be visible (and deposits will be visible inside).
- Sagging corrugation. If the distance between the sewer socket and the toilet outlet is large, the design will inevitably sag. Due to the unevenness of the walls, deposits are constantly deposited, which pull the pipe down. In addition, water accumulates in these slack during operation.
What type of corrugation to use?
At the moment, on sale you can find such options for corrugated pipes:
- Reinforced. This is the toughest option among others. When buying such a pipe, you need to consider the design features of the toilet. The reinforced structure contains a wire, thanks to which the walls become rigid. The price of such a pipe will be higher, but it also lasts longer.
- Combined. Suitable for non-standard installations (for example, if it is decided that the toilet will lag behind the wall by a certain distance).
- Drain This is a universal option. Such a pipe will connect to any communications, whether they are plastic or cast iron. In addition, the cost of the drain corrugated pipe is quite affordable.
Also, when choosing, you need to ensure that the product does not have defects. In most cases, it is a brittle material that is easily damaged during transportation. Therefore, the condition of the goods must be inspected before purchase.
To summarize
So, we found out how to replace the corrugation on the toilet. As you can see, this operation can be done with your own hands. But you need to understand that this design is not the most durable, and sometimes it is worth giving preference to more reliable analogues.
