Drain cross: tips on choosing and installing

Installing or repairing sewage systems is a very demanding process that requires certain skills from the workers. However, with a little preparation, even a novice master can handle it. Especially if you only need to replace the cross of the sewer or tee.

Phased process

First we need to say that this article will describe the simplest repair process, when the cast-iron sewage system was originally installed and the replacement was made for a PVC product. In this case, only the spider for sewer pipes will be affected, and the riser itself will remain in place. The fact is that it is this part that most often becomes unusable.

Dismantling

First of all, you need to remove the old part. However, it must be remembered that even if it has cracks, its strength does not become less. In this case, breaking it with a hammer is not recommended, as this may damage entire elements.

Given this, the instructions for dismantling offers to use cutting wheels and grinders. This will also prevent pieces of iron from getting inside the pipe, which naturally leads to clogging.

If the repair is done with their own hands in a multi-storey building, then before starting work they block the water and ask their neighbors not to use the sewer system throughout the tower. Otherwise, you can constantly expect waste to spill over your head.

Tip! As soon as a small hole is formed in the pipe, then it is necessary to shove a large piece of rag into it, which should become a kind of stopper and block the hole so that no debris gets into it.

Part selection

There are several types of similar parts that differ in their design.

However, some masters try not to change the configuration of the equipment, choosing the exact same element as it was before.

• The simplest crosses are type 110x110x110. This means that all its outlets have a given diameter.. Such a part can be suitable for mounting with a recumbent system of the same parameter, since in the future it can only be reduced by means of a special insert.
• Marking type 110x110x50 45 assumes that one sewer outlet from the riser will have a diameter of 110, and the second 50. At the same time the smaller pipe is located at an angle of 45 degrees. This is very convenient when wiring to the toilet and a separate outlet to other points.

• Special attention deserves a two-plane cross.. In relation to each other, its taps are located at an angle of 90 degrees, and not 180, like all other products. Also, one sleeve can be used to create an inspection hatch, which is very useful during operation.

Tip! It must be said that there are many combinations of pipe branches, which differ only in diameter and angle at which they are located. Therefore, you should not choose inconvenient parts, because you can always find the necessary element.

Installation

First you need to say that you need to purchase special adapters that will connect PVC and cast iron pipe. Their price is sometimes quite high, but if such elements are not used, you will have to do the docking yourself using available tools, which does not always guarantee quality.

The rest of the installation is done by connecting all the parts, by installing them one to another. In this case, you can face the fact that the inner sealing rubber prevents the elements from sliding down. That is why it is recommended to use a special gel or petroleum jelly to reduce friction.

Tip! When installing it is very important not to create distortions. It is through the irregularities of the joint that the water will flow.

Conclusion

After reading the video in this article, you can more thoroughly examine the process of installing sewer systems and this part. Also, taking into account the article proposed above, it is necessary to conclude that even the simplest crosspiece has a lot of varieties and types, among which there will definitely be one that is ideal for work.
