Sewage system drain. Which sewer drain to choose - plastic, cast iron or stainless steel? A dry seal is the best protection against the penetration of unpleasant odors from the sewer

plumbing drains in Moscow

Plumbing drains are water collection outlets installed in the floor and connected to the public sewer network. Their use allows for targeted removal of water spilled on the floor into the sewer system. Drains are used in two cases: when there is no shower tray and there is a constant need to drain water in the shower room, and also when there is a risk of regular water ingress onto a certain area of ​​the floor in the bathroom or kitchen.

Plumbing drains can be made of galvanized stainless steel or polypropylene. Metal drains are more expensive and stronger, plastic ones are cheaper and more hygienic, so the choice of a specific drain model is yours. It can be determined, among other things, by the design of the bathroom - as a rule, polypropylene drains are gray or white, stainless steel drains are glossy metal surface silver color.

Plastic plumbing drains deserve special mention. They are made from particularly hard polymers that are resistant to both temperature and mechanical stress, and therefore are often not inferior in operational characteristics and service life compared to their metal counterparts. Our assortment includes shower drains from two Russian manufacturers - ANI PLAST and ALCA PLAST. The line of both manufacturers is distinguished by a variety of diameters and exit directions, and grille patterns (for some models it is made of stainless steel).

Based on the type of connection, plumbing drains are divided into drains with direct and side exit. The choice of model depends on the configuration of the sewer network in your case. This factor, as a rule, does not affect the rate of water removal. The speed of water drainage depends more on the number and location of drain holes on the drain outlet.

To collect liquid from the surface of the ground or the floor of a shower, toilet and other rooms, various receivers are used. In domestic and industrial conditions, a plastic sewer drain or a stainless steel model is used for such purposes.

Vertical and horizontal sewer drainage ladder GOST 1811-97 is used to drain water from various surfaces(in the shower, at the sink, from the toilets). These devices are classified depending on the material from which they are made, the type of installation and additional elements.

According to the material there are:

1. Metal. They are made from cast iron, stainless steel and aluminum. Cast iron elements transport water well, have high resistance to moisture and steam, but are very heavy, so they are not used for plastic water supply systems. For such purposes, lighter ones are installed - models made of aluminum and alloy steel. Sometimes in private homes a metal brass drain is used - it has Beautiful design and high anti-corrosion properties, are distinguished by a high price;
2. Plastic sewers are made from recycled plastic (PVC or HDPE). They do not corrode and are very light, but they can crack under the pressure of wastewater.

By design sewer drain can be vertical and horizontal. Horizontal floor drain can be used for showers, outdoor cabins, toilets in apartments and private one-story houses. Vertical trays have a capacity many times higher than horizontal ones, but they cannot be installed in multi-storey buildings. For any of the described models, the diameter varies from 70 to 180 mm, and the height up to 300 mm. The shape of the drain can be round, square, rectangular, oval and individual (designed to order).

Depending on the configuration, the sewer drain can be equipped with a water seal or a dry seal, with heating, lighting (ACO ShowerPoint) and other features. Let's look at each of them:

How to choose

The dimensions of the sewer drain play a key role. For domestic use, models with a diameter of up to 100 mm are used, while at the same time, industrial drains can have a cross-section of up to 250 or more. Another important parameter is throughput. It is determined by the material of the funnel and its diameter.

1. For a drain made of steel or aluminum with a diameter of up to 50 mm, the optimal pressure indicator is 1 l/s;
2. For pipes with a 100 mm outlet, the pressure must be at least 2 l/s. They are additionally strengthened, since they belong to pressure drains.

It is worth considering that nickel-plated polypropylene or stainless steel drains have a higher throughput than cast iron. Therefore, it is used for rooms where the water pressure is quite high (in in public places, houses with more than 4 residents).

Connection

To install a sewer drain, it is necessary to prepare a drawing of the water supply and drainage system. Installation of the device can be done in literally half an hour, if you have all the necessary devices and elements at hand.

It is worth noting that when using a funnel in rooms with high humidity, the pipe is additionally waterproofed. This is necessary to prevent moisture from penetrating under the floor surface. Once every six months, the drain is cleaned; mechanical brushes, special chemicals or biological compounds can be used to clean it.

Characteristics of the vertical ladder

The drains are made of polypropylene or high-strength cast iron and are capable of performing their functions at temperatures up to +90 degrees. Optimal conditions for use is temperature regime 40-55 degrees with a short increase to +65 degrees.

Cost of vertical ladders

The cost of drains depends on the grate material and size. A product made of polypropylene with a stainless steel grill has an approximate cost of 135 rubles. A similar drain, but with a cast iron grate, will cost 250 rubles. A plastic sewer drain, the price of which ranges from 100 to 500 rubles, must be selected taking into account the area of ​​use. For suitable for home product with a steel grid. And only cast iron ladders can be installed at the enterprise.

Sewage vertical drains from the TATPOLIMER company are distinguished by their high reliability and quality. The company's specialists will help you select parts for installing a sewer system.

Many people prefer to create their own bathroom design. Now you can move away from the usual models of shower cabins and bathtubs and create an original shower cabin with an unusual shape and finish. Creating a pallet yourself is not too difficult a task, but in order for everything to work without failures, it is necessary to equip a sewer drain. A sewer drain will help with this, which must be correctly installed in the floor.

Types and features of sewer drains

These details may differ in different ways; first of all, they can be divided according to material, from which ladders can be made. Each of them has its own characteristics, pros and cons, and their purpose also differs:

The ladders may vary and according to other criteria:

• Vertical the ladder has a large throughput system, but due to this it is necessary special conditions for installation.
• Horizontal ladders can be used in all rooms, regardless of the number of floors in the building; they are used much more often.

Also changes gangway size, its height depends on the model and varies from 75 mm to 180 mm. The shape of the ladder, or more precisely, its upper grille, can be round, square or rectangular.

All ladders have a similar structure, which includes the following elements:

Gangway selection criteria

Choosing a ladder is a responsible task, since performing it dismantling extremely difficult. To replace already installed ladder you will have to disassemble the floor covering and remove the screed. First of all, when choosing a product, its size is taken into account; it is usually determined based on the average volume of waste. Medium-sized drains are usually suitable for shower stalls with a good access system.

The ladder material does not have of great importance, most often used plastic. But you can also choose of stainless steel, it does not corrode, is durable and reliable. Heavy cast iron structures are usually not installed in apartments. The diameter and direction of wastewater discharge is very important.

To select a drain for subsequent installation in the shower system, you can select optimal characteristics, but some points need to be taken into account on an individual basis.

Sewer drain installation technology

The very first and most important condition for installing any ladder is the slope. flooring. It must be done in such a way that wastewater could gradually and easily fall into the drain. Usually the ladder is installed in place of the shower stall, so many people finish the floor precisely tiles. Rules for installing a sewer drain that must be followed:

• The ladder grate must be on the same level with top floor covering.
• Floor finishing begins directly from the ladder; tiles must be laid from it to the walls.
• All seams between tiles must be no more than 2 mm.
• Their grout is only moisture resistant.

Installing a ladder has its own subsequence:

This option for installing a drain allows you to maintain the height of the floor in the bathroom at the same level as other rooms, so the work is quite labor-intensive. You can go another, simpler way, you need to build wooden flooring or iron frame, the main thing is that it is durable. Next, the outlet from the drain to the sewer pipe is installed; it is also important to maintain the slope.

The elevation is done by constructing a screed, it is necessary to perform installation of formwork, put waterproofing material and reinforcing mesh. The ladder is installed so that its level is slightly higher than the formwork, that is, on par with facing material. Next, concrete is poured; you always need to control the slope of the pipe. After it hardens, the formwork is disassembled and Finishing work.

Installing a ladder yourself is not an easy task, but anyone can cope with it. It is important to strictly follow the rules for installing a sewer drain and the sequence of work.

Sewer communications are systems (sewage and drain) consisting of many individual components. One of them is a sewer drain, which is designed to perform the function of draining/receiving water into the sewer system.

Sewage drains have their own characteristics. And their classification is carried out based on the materials with which they were made. Each type of these products has distinctive characteristics.

Classification and features of sewer drains

1. Cast iron. This type of sewer drains is used exclusively in industrial production, where working conditions are characterized by an increased degree of complexity. These products, unlike other types of sewer drains, have the most massive and weighty design. They are easy to operate and unpretentious in maintenance. However, installing cast iron sewer drains is not an easy task, requiring certain knowledge and skills. The main advantages of these products include their high wear resistance and throughput. And the disadvantages include considerable weight.
2. Steel. They are made of stainless steel, like sewer trays, and are used in areas where strict compliance with sanitary standards is required. In most cases they are installed in medical institutions and in catering establishments. The use of steel sewer drains as separate drainage systems allows solving local problems. They can also be used in combination with water supply trays. Not only the body of this type of product, but also the lids and grates are made from stainless steel. This makes it easy to clean products from the effects of corrosion.
3. Plastic. These products of this type can be installed in almost any room:

• swimming pools;
• laundries;
• shower cabins;
• toilets;
• small specialized laboratories.

Before installing them in the floor, it is necessary to make a slight slope, which will allow the water to drain more smoothly, getting inside the drain hole structures.

Plastic sewer drains are equipped with siphons, thanks to which unpleasant odors of sewer water do not have the opportunity to penetrate into the premises. And the presence of a grid prevents large particles from getting inside sewer pipes, thereby preventing the formation of congestion.

The main advantages of this type of sewer drains are:

• light weight (this greatly facilitates installation/disassembly);
• resistance to aggressive environments;
• durability;
• affordable price;
• ease of care.

Thanks to these advantages, plastic sewer drains are especially popular.

From the wide range of sewer drains on the market, you can choose the product that is most suitable for you based on the following parameters:

• the ability to adjust the depth of the product (taking into account the height of the floor);
• attractive design;
• throughput.

When choosing a sewer drain, first of all, it is recommended to determine which of the modifications will achieve the intended goal. Happy purchasing
