What is a ladder in the sewer. A dry seal is the best protection against the penetration of unpleasant odors from the sewer. Ladder made of stainless steel

Any sewer system has holes for water flow, which are traditionally closed with the help of special elements - ladders. These products are widely used in residential and non-residential premises.

A sewer ladder with a water seal performs several functions:

  • drains water;
  • filters out large contaminants;
  • prevents penetration unpleasant odors.

Ladders are made of cast iron, stainless steel or plastic.


All of these plumbing products may have various device and dimensions, but there is a certain set of parts that make them up:

  1. Frame. It is a tube with a widening in the upper part, resembling a funnel and acting as a drainage system.
  2. Front panel (grille). It is a decorative element of the design, simultaneously acting as a filter.
  3. Siphon. Designed to prevent the penetration of odors, it is found in three types: with a dry seal, mechanical and hydraulic seal.
  4. Sealant.
  5. Clamping elements.

According to the type of installation, ladders are horizontal and vertical. The former are used more often, as they provide more convenient water drainage. However, vertical ones have a much higher throughput.

The shape of the drains can be: round, square, rectangular, etc. The diameter of the drain hole can also be different. For outdoor installation, they are made of the most durable material - cast iron.

How to choose the right ladder

When choosing a sanitary drain, it is important to pay attention to the type of shutter. If you need to make a drain hole in a room where water is often drained, the best choice is a siphon with a water seal. With a rare drain, a dry shutter will suffice. Products with a mechanical shutter are mounted in non-residential premises.

An important selection criterion is the direction of the outlet and its diameter. Horizontal shower drains are available with straight or angled outlets. Vertical - downward. In residential buildings, it is recommended to install a shower drain with a drainage diameter of 50 mm, their throughput is 0.7 l / s. This is enough for the smooth operation of the sewer system.

In public areas, products with an outlet diameter of 100 mm with a flow rate of 2.1 l / s will be required. Under these conditions, stainless steel ladders are traditionally mounted.

Plumbing drains are sockets for collecting water, installed in the floor and connected to the public sewer network. Their use allows you to ensure the targeted output of water spilled on the floor into the sewer. 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 to a certain area of ​​the floor in the bathroom or kitchen.

Sanitary drains can be made of galvanized stainless steel or polypropylene. Metal ladders are more expensive and stronger, plastic ones are cheaper and more hygienic, so the choice of a specific ladder model is up to you. 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 ladders deserve special mention. They are made of extremely hard polymers that are resistant to both temperature and mechanical stress, so they are often not inferior in terms of performance and service life to their metal counterparts. Our product range 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 outlet directions, a grate pattern (in some models it is made of stainless steel).

According to the type of connection, plumbing ladders are divided into ladders with a 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 rate of water drainage depends more on the number and location of the drain holes on the outlet of the ladder.

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

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

Classification and features of sewer ladders

  1. Cast iron. This type of sewer drains is used exclusively in the field of industrial production, where working conditions are characterized by a high degree of complexity. These products, unlike other types of sewer ladders, have the most massive and weighty design. They are easy to operate, unpretentious in maintenance. However, the installation of cast-iron sewer drains is not an easy task, requiring certain knowledge and skills. The main advantages of these products are their high wear resistance and throughput. And the disadvantages include a lot of weight.
  2. Steel. They are made of stainless steel, like sewer trays, they are used in areas in which it is required to strictly observe sanitary norms. In most cases, they are installed in medical institutions and at public catering enterprises. The use of steel sewer ladders as separate drain systems allows solving local problems. It is also permissible to use them in combination with water trays. Stainless steel is used to make not only the body of this type of product, but also covers, as well as gratings. 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:
  • 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 most smoothly, getting inside the structures of the drain holes.

Plastic sewer drains are equipped with siphons, thanks to which unpleasant odors sewage water unable to enter the premises. And the presence of a grid does not allow large particles to get inside the sewer pipes, thereby preventing the formation of congestion.

The main advantages of this type of sewer ladders are:

  • light weight (this greatly facilitates installation / dismantling);
  • resistance to aggressive environments;
  • durability;
  • affordable price;
  • unpretentiousness in care.

Thanks to the listed pluses, plastic sewer ladders are especially popular.

From the wide range of sewer drains on the market, you can choose the product that is most suitable for you in terms of 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 ladder, first of all, it is recommended to determine which of the modifications will achieve the intended goal. Successful acquisitions

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

Types and features of sewer drains

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

The ladders may differ and according to other criteria:

  • Vertical the ladder has a large access system, but due to this, special conditions for installation are required.
  • Horizontal the ladder can be used in all rooms, regardless of the number of storeys of the building, they are used much more often.

Also changes ladder size, its height depending on the model and varies from 75 mm to 180 mm. The shape of the ladder, or rather, its upper grate, can be round, square or rectangular.

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

Ladder selection criteria

The choice of a ladder is a responsible task, since it is 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, usually it is determined based on the average volume of drains. Medium-sized drains are usually suitable for showers. with a good access system.

The material of the ladder has no of great importance, most commonly used plastic. But you can opt for of stainless steel, it does not give in to corrosion, is durable and reliable. heavy cast iron structures in apartments are usually not installed. The diameter and direction of the wastewater outlet is very important.

To select a drain with subsequent installation in the shower system, you can select optimal performance, but some points need to be considered individually.

Sewer drain installation technology

The very first and most important condition for the installation of any ladder is the slope. floor covering. It must be done in such a way that wastewater could gradually and easily fall into the drain. The ladder is usually installed in place of the shower, so many floor finishes are performed exactly tiles. Rules for installing a sewer ladder, which must be observed:

  • The ladder grate must be on the same level with top flooring.
  • Finishing the floor starts directly from the ladder, the tiles must be laid from it to the walls.
  • All seams between tiles must be no more than 2 mm.
  • Their grout is made only moisture resistant.

The installation of the ladder has its own subsequence:

This version of the installation of the ladder allows you to keep the height of the floor in the bathroom on a par with other rooms, so the work is quite laborious. You can go another, simpler way, you need to build wooden flooring or iron frame, the main thing is that it be durable. Next, the installation of the outlet from the ladder to sewer pipe, it is also important to withstand the slope.

The elevation is done through the construction of a screed, it is necessary to perform formwork installation, put waterproofing material and reinforcing mesh. The ladder is installed so that its level is slightly higher than the formwork, that is, on a 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, performed Finishing work.

Installing the ladder yourself is not really simple task but everyone can handle it. It is important to strictly follow the rules for installing the sewer drain and the sequence of work.
