When choosing plumbing fixtures for arranging a bathroom, many people forget about the drain and overflow for the bathroom, and in vain, because the high reliability of this device is a guarantee of the safe use of appliances and plumbing in this part of the house.
We will provide a description of the most popular models, new products, guide you by price and the best manufacturers, advise which company is best to purchase a product, define the main criteria, recommendations for a successful choice.
The design of modern bathtubs provides for a special “overflow”, which is integrated into a single system with sewerage, preventing water overflow. There are many types of drains, they are made of different materials, components, consist of combined pipes or have a solid, cast form; the design of the siphon may vary from model to model. However, all this diversity is divided into three main groups: classic, semi-automatic, automatic.
Knowing what types of products there are will play a good role in the future when repairing it. The design of some drains complicates regular cleaning of hair and debris, while for others these manipulations are easy. Continue reading the article to learn more specific details about each of the common drain types to better understand their functionality when it comes time for replacement or cleaning.
Main types
Let's look at several types of products common in Russia, suitable for cast iron, steel or acrylic bathtubs.
1. Classic
This system is a familiar plug that closes the drain at the bottom of the bathtub, integrated with the sewer system. It has several undeniable advantages:
- design features make it easy to install the equipment and clean it in case of blockage;
- The large size of the pipe holes provided for drainage can easily cope with intense water flow and prevent flooding.
The main disadvantages include the nondescript design.
2. Semi-automatic
An improved design with an attached rotary handle, which with the help of a cable opens the shut-off valve at the bottom of the bath. Let us note several advantages of this mechanism:
- since the regulator that controls the plug is located above the water level, you can close it without getting your hands wet;
- attractive look.
The main disadvantages include:
- frequent need to clean the product;
- discomfort while taking a shower due to the drain cover, which cannot always be removed. Mechanical damage to the plug and cable often occurs.
3. Automatic
The design of such a drain includes a plug with a built-in spring that responds to its pressing. The system is often called “click-clack” because of the sound made when pressing on the mechanism. Let us outline the advantages of the product:
- ease of use due to the small number of parts;
- ergonomics, visual appeal.
The disadvantages include:
- lids that often fail;
- breakdown of corrugated hoses at joints.
It is necessary to carefully consider the purchase, so as not to make a mistake when choosing, purchase only the best products. To replace failed elements, you must use parts from the same manufacturer.
↑ 4. Installation
You can install the drain and overflow yourself, but it is important not to forget that the tightness of the bathtub in the future depends on the quality of the work. However, despite all the responsibility, installation of the system can be carried out by a non-professional; you just need to listen to the advice of specialists.
↑ General recommendations:
- Follow a certain sequence in your work;
- Use special sealants to process connections;
- When tightening parts, be careful not to strip the threads;
- All elements must be tightened one quarter of a full turn after hand tightening;
- If you cannot tighten the connection, you need to check whether the nut is level.
Installation begins after the bowl is secured to the support. The bathtub must be leveled and fixed. It is also necessary to leave a height gap between the floor and the tank (from 150 mm or more).
↑ Correct sequence:
- The bottom hole of the bathtub is connected to a tee. In this case, you need to process the connection using a sealant and secure the elements with a screw;
- Next, attach the siphon and secure it with the tee outlet with a nut. A rubber cuff can be used as a seal here;
- The overflow neck is connected to a side curved tube (siphon);
- The process is completed by connecting the siphon to the sewer pipe. For this purpose, a special spout pipe is used;
- During each connection, you should remember to lay the seal.
After installation is complete, you need to check the bathtub for leaks. The bowl is filled with water, then you need to carefully examine all the joints and connections. If drops appear on the surface, tighten the elements more tightly and re-treat with sealant.

How to choose the right drain material
Build quality and wear resistance of all parts of the equipment are the key to successful operation of the product for many years:
- Plastic is a relatively inexpensive raw material for the manufacture of budget drains. It does not rust, but at the same time, the entire system as a whole has an unpresentable appearance, resistance to mechanical stress, and strength may require the best.
- The ideal option for drainage systems is metal. It is durable, increases the warranty period of the product, and has an attractive design. Typically, copper, brass or bronze is used.
During construction, it is preferable to use equipment made from these materials, although in the “short term” you will not see much difference between plastic and metal, it will appear with long-term use.
Siphon rating
When considering candidates for inclusion in the top, we took into account the level of demand, the demand for goods, and analyzed which brands buyers prefer more often. As a result, the list was significantly narrowed, after which we compared the following characteristics:
- Device type;
- Principle of operation;
- Body shape;
- Materials;
- Diameter of connection, outlet;
- Dimensions, pipe height, weight;
- Equipment;
- Possibility of cleaning;
- Speed, ease of installation;
- Design, demanding installation of the cabinet.
The result of the comparative analysis was a top list of 10 positions. For convenience, we have divided it into categories so that you can go to the type you are interested in, taking into account specific tasks - units for a bathroom sink, under a kitchen sink, a shower tray or a washing machine. Customer reviews determined the pros and cons.
Device Features
Any model has common structural parts:
- top overflow;
- a lid covering the hole at the bottom of the bath;
- pipes made of metal or plastic;
- siphon, including bottle siphon.
All elements are connected through a series of gaskets; the more secure the fastenings, the greater the chances of not flooding your neighbors and getting out of the water unscathed. The overflow, which controls the water level in the bath, is important. The siphon functions as a water seal, which prevents the entry of unpleasant odors from the sewer.
↑ 1. Operating principle
The piping (or drain-overflow) organizes the drainage of water from the bathroom tank into the sewer pipe. The device consists of several hoses and tubes that are connected to each other, with a sewer system and two bath openings. The top hole of the tank prevents water from overflowing, the bottom hole is responsible for draining.
If all components are installed correctly, the likelihood of overflowing the bathtub is reduced to a minimum, but there must be moderation in everything. Sometimes water fills the bowl faster than it drains, in which case you can flood the floor in the room.
Differences between drains
You can see two main types of systems in plumbing stores, in addition to the classic one:
- semi-automatic;
- automatic.
In the first, the plug is opened using a control cable by turning the overflow cap.
The second trim has an attractive design; water is released mainly by pressing the plug. The bath is filled through an overflow hole that is connected to a water pipe.
Tips for care and use
All drain and overflow systems require appropriate care. This is the only way to preserve their original condition and performance, ensure durability and high efficiency. Devices must be inspected regularly to ensure there are no mechanical damage or leaks.
Also, we must not forget about additional events:
- to prevent the accumulation of deposits and scale, the siphon is washed every three months with hot water with the addition of citric acid or suitable chemical oxidizing agents;
- approximately every six months, thin rubber gaskets that have lost their elastic properties are replaced;
- The water seal, which collects various contaminants and debris, is periodically cleaned.
If chips and cracks are detected during a visual inspection, the siphon must be replaced. Such malfunctions provoke flooding of premises and cannot be repaired.
The following article will introduce you to the intricacies of installing a conventional siphon on a bathtub, the contents of which we recommend that you familiarize yourself with.

The best manufacturers
The name of the manufacturer is a guarantee of quality, and when it comes to such important plumbing equipment, it is better not to skimp on quality and trust only trusted companies. It is difficult to list all the worthy ones - we will mention only the largest and most trusted manufacturers of drains and overflows:
- GROHE is a famous German company that offers automatic and semi-automatic siphons. The quality, design, assortment are at their best, but the prices are appropriate;

Bath connection technology
The procedure for connecting the bathtub to the sewer system
The connection procedure is as follows:
Assemble the siphon in accordance with the instructions attached to it, paying special attention to all the necessary sealing gaskets
The plastic fasteners are tightened by hand, acting very carefully. Tools are not used, as using them can break the part.
After the device has been installed, one end of the pipe is connected to it, and its other end is brought to the sewer drain hole and a connection is made. Connecting the bathtub drain must be accompanied by careful control over the density of the assembled joints to ensure a high degree of tightness.

Pro tip:
Pro tip:
If the slightest malfunction is detected, it is necessary to eliminate them immediately, otherwise during operation it will be necessary to replace defective elements of the system.
- If the sides of the bathtub are tightly adjacent to the walls, the joints must be carefully sealed so that water does not have the opportunity to penetrate under the bathtub.
Connecting the bathtub to the water supply
Just like connecting a bathtub to the sewer with your own hands, it is also possible to connect to the water supply and install a mixer yourself. You don't have to call a plumber to do this.
Let's consider this technology:
- A shut-off valve is installed on the pipe in front of the fittings, the presence of which is necessary to shut off the water when replacing the mixer or in case of repair.
- Eccentrics are attached to the fittings located on the mixer (first by hand, and then tightened with a key). In this case, FUM tape or a specialized thread is used, intended for connecting elements of the plumbing system.
- Decorative attachments are put on the eccentrics.
- On the mixer, rubber or silicone gaskets are inserted inside the threads, and then the mixer is screwed to the eccentrics (in this case there is no need to use FUM tape or thread).
Pro tip:
The bathtub connection diagram must necessarily include a check of the quality of the work performed - if leaks are detected in the mixer, the gasket is replaced - it is possible that the leak occurred due to a defective gasket.
- The mixer is screwed on both sides at the same time. In this case, the gaskets are evenly sealed.
- If the bathtub comes with a mixer when purchasing:
- then the permissible level of pipe height is below the level of the bathroom, since in this case the connection is made using reinforced hoses;
- it is not necessary to align the ends of the pipes - such hoses are very flexible;
- The basic rule in such a situation is to ensure that the length of the reinforced hose is slightly longer than the distance from the bathroom to the end of the pipe.
After completing all operations to connect the bath to the water supply and sewerage, turn on the water and observe for leaks. If there are leaks, then you need to make sure how well the gaskets are secured, and also make sure the quality of the gaskets themselves (if they are of poor quality, you will have to replace them).
Following these simple rules will allow you to efficiently connect the bathroom to the sewer and correctly install the mixer. With this approach, the bathtub will last for many years!
Bath connection process
Most often, new bathtubs are purchased with a set consisting of:
- Siphon and connecting pipes;
- Drain-overflow systems.
In most cases, this is a single unit, which has its own installation features:
- On acrylic bathtubs, thanks to the preliminary assembly of the load-bearing frame, the siphon is installed immediately (on an inverted bathtub);
- The siphon is connected to cast iron and steel bathtubs after installation.
For reference: Installing steel bathtubs on a brick base narrows the work space. Therefore, experienced plumbers pre-install individual components on the bathtub.
Tip: Your main task is to make all connections airtight. When installing a bottle siphon, the kit always includes special gaskets that are required to be used.
We arm ourselves with the assembly diagram and get started:
- First, we install a drain and overflow on the bathtub, because... after installing it close to the wall, this will be problematic;
- After installing the bathtub in place and fixing it, we assemble the receiving unit (socket with pipe and protective mesh). We put a gasket on the edge of the socket, insert it into the drain hole of the bathtub and from below, also with a gasket and a nut, we connect the parts into a single unit. Depending on the design, the mesh can either be screwed on or be removable;
- The time has come to assemble the siphon. We assemble the glass according to the attached diagram and attach it to the protruding pipe of the receiving unit. We fix it with a plastic nut, tightening it by hand;
- Don’t forget to connect the drain hose of the overflow drainage system - we put its end on a special branch;
- We insert a corrugated or plastic pipe from the siphon into the sewer tee using rubber adapters.
Tip: adapters play the role of a seal, allowing you to reliably seal the entire structure.
Conclusions: we are sure that now you know almost everything about sewerage and how to connect a bathtub. All that remains is to put the acquired knowledge into practice, and spend the money saved on work on purchasing stylish accessories for the bathroom.
Arrangement of a bathroom implies the obligatory connection of the bath to the sewerage system and water supply. These plumbing jobs can be easily done with your own hands, even without prior experience.
Dismantling the old device
Before assembling the bath siphon, it is necessary to dismantle the old device. And this task sometimes turns out to be much more difficult and labor-intensive than directly replacing it with a new model. The complexity of the task depends on the design of the siphon, as well as the distance between the floor and the bottom of the bowl required for maneuvers. Depending on the characteristics of the equipment being dismantled, the task can be performed in the following ways:
- If the siphon is plastic, Soviet-style, then to dismantle it you will need pliers and a screwdriver. First you need to use a slotted screwdriver to unscrew the screws that secure the drain and overflow. Then carefully remove the grates, and then disconnect the hose from under the bathtub from the overflow and sewer.
- If the siphon is old, cast from cast iron or copper, then dismantling the trim can only be done using a grinder with a 115 mm cutting disc. When using an angle grinder, you need to wear safety glasses and gloves. With its help, you need to carefully cut through the drain in sectors in a circle. Then insert a screwdriver into these cuts, tapping it with a blade, and separate the drain from the bathtub. Do the same with overflow.
Causes of incorrect height ratio
The main reasons for the discrepancy between the levels of the tee and drain holes should be considered:
- errors made during installation or reconstruction of the system;
- the use of modern types of plumbing that require a different system configuration;
- re-equipment of kitchen or other premises, requiring installation of sewerage under the floor covering.
Owners of cafes or bars that open in unprepared premises often face similar problems. They constantly have to solve plumbing installation issues. For example, how to install a toilet if the sewerage system is higher than the drainage elements. In addition, many modern appliances are equipped with a floor outlet, which requires the assembly of a separate line.
The nuances of laying plastic pipes
The connection of two adjacent pipes occurs using a fitting. More precisely, the pipe is hermetically sealed in the elastic band of the fitting. The pipe must be inserted all the way
It is very important that the fitting and pipes are clean. Otherwise, over time, the sealing of the connection will be broken. To improve the tightness of the connections, the ends of the pipes are treated with a soap solution
To improve the tightness of the connections, the ends of the pipes are treated with a soap solution.
The most difficult process is installing the riser. Therefore, it is from this site that the installation of the sewer system begins. First, the tee is installed. To do this, a rubber cuff, which is pre-lubricated with sealant, is placed in the lower socket and connected to the tee. Clamps are used to secure the pipes and riser to the wall.
After assembling the riser, the pipes are led to the places where the plumbing fixtures will be located. Immediately you need to provide for the presence of a slope towards the riser. It should be within 2 cm per 1 m of pipe. If sewer pipes are laid in wall grooves, then clamps are used to securely fasten them.
After installation work, all connections are carefully checked. The plumbing drain elements are connected to the pipes. This procedure is not complicated. The only problem that can arise is connecting the bathtub to the sewer.
Semi-automatic
The result of improving the classic strapping system was a semi-automatic system. If we compare it with its predecessor, then it took the drain siphon and drainage pipes from it. As for other features, in this regard it has changed noticeably.
In more detail, its design is represented by the following elements:
- Control block. The purpose of this system is to raise and lower the plug. A similar function can be performed by a button, rotary ring, handle or valve;
- cork. Here it serves as a valve;
- cable It is necessary to control the position of the plug.
The operation of the control unit is based on the following principle: if you press the button and turn the valve, the cable will begin to move. If the latter is tightened or loosened, this will lead to the rise or fall of the plug. A special feature of this design is that a space is allocated for the overflow hole behind the control unit . The external, visible elements used in this design usually have an attractive design, thanks to which such a system will give the interior a more aesthetic appearance.
Among other advantages that the design in question has, we should highlight the high level of comfort when using the cork. To pull it out or lower it, the owner does not even have to bend over the bathtub and wet his hands.
Which siphon is better
After getting acquainted with the 10 nominees and the criteria for the right choice, the final decision on which siphon to buy will be much easier to make. Having compared all the pros and cons of the described top positions, Vyborexperta.ru especially noted:
- Viega 5755 366 681 – chrome-plated sink siphon with a streamlined body made of silver brass, reliable protection against leaks;
- AlcaPlast A41 – high quality components, resistance to chemical compounds, ease of installation;
- Prevex P-loc Pl-d9cf5-Sink siphon – model with 3 outlets for connecting to a large sink, washing machine, dishwasher;
- AlcaPlast A491CR - self-cleaning design with a rotating elbow, effective water drainage;
- SantecPro AQ372P5 is a modern model with a semi-automatic click-clack release.
A siphon is an important addition to plumbing, without which a safe drainage system is impossible. If you have no experience in selecting such products, thanks to the subtleties and nuances described in the review, you will cope with this task. In addition, modern modifications are so simplified that you don’t have to be a master to install them.
