Drain Cross: tips on choosing and installing

Sewer crosses are used to properly organize the entire sewer system. They are also necessary for the installation of several ramifications from the main sewer risers that carry household sewage inside a wide variety of buildings and structures, including residential and non-residential production. As a rule, such plumbing products are made of durable material and have a smooth surface from the inside, thereby reducing the risk of blockages of sewage pipes. Next, we consider their main types and features of installation, which experts advise to consider.

To date, three-plane and two-plane crosses are on the market for relevant materials.Cross is sometimes called pyatnik. Let us dwell on each form in more detail. The crosspiece refers to the types of fittings for sewage. In turn, the fitting is directly part of the pipeline.

The two-plane sewer crosspiece is used for installation of branches in two planes - from the main pipelines to sanitary devices. As a rule, they are made of polypropylene, which is considered to be very durable. Products of this type do not produce excessive noise, moreover, they can withstand water temperatures up to 90-95 degrees. They are also resistant to a variety of chemicals, and do not require additional coating or painting before use. A high-quality crosspiece has excellent elasticity, which means that when it is used, the sewer system will work without interruption for at least 30-40 years.

Despite the fact that such a detail as pyaternik for pipes is sold almost everywhere in the respective stores, it is very important to give preference to only quality versions made of good material. The cross is an indispensable thing in the sewer system, since it is she who is responsible for the ramification of the relevant communications. Especially relevant for the purchase of crosses made of PVC, but they are quite difficult to purchase in regular stores. But in many online stores with plumbing they can be selected without difficulty. Dimensions pyatnika should be selected based on the size of the sewer pipe at home.

Crosses are very often used to connect several pipes at once. Usually three or four. It is very important to remember that for the well-coordinated work of the sewage system they should be located at an angle of ninety degrees to each other. For connecting horizontal plots in the sewage system, when installing joints under the ceiling in residential buildings, it is best to use crosspieces, rather than oblique tees. Although they both proved to be due to high-quality and well-coordinated work.

Two baths, which are located on both sides of the riser, it is best to connect only with an oblique cross. It is very important to remember that oblique crosses should never be mounted horizontally. This is due to the salvo discharge of one or more branches, because of which it is possible to disrupt the hydraulic locks.

If it is noticed that the sewer riser is leaking, it is necessary to check the crossbar itself, since very often a crack can form in it, especially over a long time. Before assembly, it is best to process the joints with the help of special sanitary silicone - thanks to its anti-fungal and anti-corrosion properties, it is possible to achieve high-quality and reliable pipe joints for many years. Many wonder which crosses are better: cast iron or PVC. Of course, that the latter, because they have a longer service life and they are less whimsical in installation.
