TOP 10 Best Siphons – Rating 2021

The primary and main function of the siphon is to receive the draining water and redirect it to the opening of the sewer network. The second is to prevent stale air from entering the shower room from the sewer. The third is collecting waste that ends up in the water. For a comprehensive solution, valve designs (another name for siphon) have been developed.

Gate valves are installed on all plumbing fixtures, except those that already have a valve in their design as an integral part of the structure. Shower trays do not have one, so the shutters are installed when they are installed. A special feature of shower sinks is their low installation, which limits the height of the shutter products.

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.

General working conditions

After taking a shower, water, which is usually called waste water, should be drained from the shower, or rather from the pan, into the sewer riser. By default, in all apartments there are special sewer crosses on the sewer riser, through which drains from the bathroom and kitchen are drained into the sewer riser.

Regardless of whether the riser is cast iron or plastic, the principle is the same: the apartment's sewer pipes with a diameter of 50 mm are connected through a cross to a riser with a diameter of 110 mm. Let's simplify the task in this article, we will assume that there is a cross on the riser and there is no need to change it.

The best siphons for a bathroom sink

If you are choosing a siphon for a bathroom, the design should include an overflow, which will prevent water from overflowing the sides of the bathtub. In addition, the second important element is closing the drain for filling. Three nominees, the best products according to VyborExpert, meet precisely these requirements.

Viega 5755 366 681

Semi-automatic bath siphon from the German brand “Viega” with a streamlined design and an outlet diameter of 1 ¼. Creates an air exchange barrier between the cavity of the sewer pipes and the bathroom. This prevents unpleasant odors.

Recommendations for installing a low tray with legs

The small size of siphons for low pallets requires special care during installation. Correcting errors is much more difficult than with standard pallets, keep this in mind and perform all technological operations very carefully. How to install a siphon on a low tray?

Step 1. Remove any remaining dried adhesive from the mastic used for tiling the walls. During tiling, the bottom row is always not completed; it is installed only after installing the shower tray. Remove the mastic with a metal spatula. Remove construction debris from the bathroom floor.

Removing glue residue with a spatula

Floor cleaning

Practical advice. It is much easier to remove the adhesive immediately after laying the last row of tiles, when it has not yet hardened. Use a damp cloth and rinse it several times in clean water.

Step 2. Cover the area of the wall near the pallet with a new layer of waterproofing. The height of the area is approximately 10–15 cm. We recommend using any mastic, they all cope with their tasks efficiently. The main condition is not to violate the technology, follow the recommendations of the manufacturers. The mastic can be applied with a roller or brushes; the number of layers depends on the condition of the base.

Application of waterproofing

Step 3. Attach the legs to the low tray. To do this, turn it upside down and place it on sheets of cardboard from the packaging; the cardboard will prevent scratches. Choose the optimal location of the legs, taking into account the size of the pallet and the characteristics of the load-bearing surface. The fact is that there are options for the sewer pipe to exit directly next to the wall, and there are options for placing it at a distance. The feet must not touch the sewer pipe.

Installing legs on a pallet

To fix the legs, self-tapping screws of the appropriate length are used; they are included with the pallet. Do not replace them with stronger ones, as this may damage the front surface of the pallet. Don’t worry that they won’t withstand the loads; designers always make reliability calculations using a safety factor.

Fixation with self-tapping screws

Step 4. Place the tray with the fixed legs in place and adjust its position. You need to check horizontality in two directions; adjustment is done using special screws on the legs. After completing the adjustment, be sure to tighten the locknuts; they prevent the threads from unscrewing spontaneously.

Pallet installation and adjustment

Practical advice. It will not be possible to adjust the position of the low tray in one go. First, place a level on the shelf of the pallet against the wall and set it horizontal. Then set the level to a position perpendicular to the original one, again set it horizontal. After this, you need to once again adjust the horizontality of the pallet shelf against the wall.

Checking the tray position

Step 5. Insert a pencil into the drain hole and draw a circle on the floor. The siphon body for the low tray will be placed in this place; draw lines on the wall along the bottom edge of the shelves. Remove the tray.

Position mark

Marking the position of the siphon body

Step 6. Use a ruler to make the lines clearer. They serve to mark the places where the side supporting elements of the pallet are fixed.

Drawing lines using a ruler

Step 7. Attach the fixing elements to the wall and mark the locations of the holes for the dowels. The upper plane of the devices must be located exactly along the line.

Step 8 . Drill holes for the dowels. The depth of the holes should be 1–2 cm greater than the length of the plastic parts. The reserve is necessary so that dust residues do not prevent the plastic parts from entering all the way. Secure the structures with dowels.

At this point the preparatory work is completed, you can begin installing the siphon. Before installation, carefully read the instructions and study the purpose of each part. If you have little experience, it is recommended to first completely assemble the siphon , this will help you better understand the technology and stages of work.

Step 1. Remove all parts from the packaging and place them next to your work area.

Step 2. Place a nut on the connection pipe of the siphon to the sewer pipe, and then a rubber seal. Insert the assembled assembly into the outlet on the body and tighten the nut. To prevent damage to the rubber seal, lubricate it with any technical oil or soapy water.

Housing, elbow, washer and rubber gasket

Connecting elements

Step 3 . Install the siphon on the place marked on the floor and measure the length of the pipe that will be needed to connect to the sewer. Use a hacksaw to cut the plastic pipe. If the pipe and pipe are located at an angle, then use an elbow. All connections must have rubber seals. Check the slope of the drain pipe; it should be at least two centimeters per linear meter.

Pipe length measurement

Trying on a pipe section

Measuring the distance between parts

Important. After cutting the pipe, be sure to remove the burrs and make a small chamfer at the end. Burrs can be removed with a sharp knife, the chamfer is made with a grinder. If this is not done, then with a high probability the thin edges of the seal will tear during connection.

Step 4: Reinstall the shower tray and place it firmly against the wall. Check the stability of the position. Press at different angles, there should be no wobble.

Step 5. Fix the bottom edge of the pallet to the terminals installed on the walls. Check the position again with a level and adjust it with the legs if necessary. All legs must rest on the floor.

Pallet fastening

Pallet installation

Step 6. Place a rubber gasket on the siphon body, lift it until it stops with the bottom plane of the pan. With one hand, support the body from below, and with the other, place a metal ring on top to secure it and screw it in place. Tighten the bolts evenly in turn on each side of the hole, do not allow distortions.

Fixing the metal ring

Step 7. Pour water into the drain and check the tightness of all connections. Check very carefully, do not rush. During operation, minor leaks are very difficult to detect; water will constantly drip in a little, building structures will be wet. As a result, the appearance of fungus and the gradual destruction of materials. In the future, liquidation will require a complex of expensive construction measures.

Leak test

Step 8 . Using a small brush and roller, apply an additional layer of waterproofing to the wall, paying special attention to the junction of the ends of the pallet with the wall.

Applying an additional layer of waterproofing

Step 9. While the mastic has not hardened, glue a waterproofing strip to it and coat the surface with mastic again. Allow time for the materials to harden. The exact time is indicated by the mastic manufacturer, but in most cases it is 24 hours.

Gluing the waterproofing strip

Applying mastic

Step 10. Install a decorative drain grate on the siphon. Check that the fastening is secure.

Decorative drain grate

At this point, the work on installing the siphon is completed, you can begin tiling the wall. Next, foam blocks are placed around the perimeter of the pallet; adjustment of the dimensions is done with a hacksaw for wood with fine teeth. Once the finishing work is completed, you can mount the walls of the shower stall, connect the mixer, etc. A correctly installed siphon for a low tray will serve well for many years, and any violations of the technology will eventually cause the need for unscheduled repair work.

DIY installation

It is better to install the siphon on the pallet at the very beginning, so that later you can check the operation of other systems when installing them.

To prevent leaks during operation, all joint surfaces are covered with sealant.

When installing a siphon on an acrylic sink, it is necessary to apply silicone to the liner closer to the threads to provide additional protection for the seam between the acrylic and the fiberglass in the drain hole of the pan. If this is not done, delamination of acrylic and fiberglass may begin in the future. Be sure to clear the sink drain hole of threads and remove the film around it.

The connections should not be overtightened so that the plastic does not burst and lasts a long time.

Before the installation procedure, the product is assembled “idle” in order to understand in what sequence its installation will occur. You need to familiarize yourself with the diagram given in the instructions, disassemble the product, reassemble and disassemble again.

You can clearly see the disassembly of the siphon in the video:

After this you can start installing it:

The pallet is installed on the base. The height of the drain hole (above the floor) is measured. The slope of the outlet pipe is checked: the slope of the line from the drain to the sewer hole should be 5-6 centimeters per meter. If the condition is not met, the shower sink must be raised to the missing height. The height of the space under the sink for installing shutter fittings should not be less than 8 cm. When the sink is installed correctly, the tray is removed. Proceed to installing the siphon.

If there is an overflow, it is mounted: one end of the corrugation is connected to the drain hole (overflow) through a pipe (O-rings must be installed), the other is connected to the body of the product. For the second connection, the pipe is threaded into the nut, and a conical gasket is put on its end (with the cone facing the body).
The outlet is mounted, for which a gasket is placed on top of the drain hole and an insert with hooks is installed (or another part, depending on the design of the product), a gasket and the top of the siphon body are installed below. The parts of the upper part of the outlet are installed.
The shower sink with the attached product is installed in place. The water seal is connected by a pipe to the sewer.
The connection is checked for leaks. If the test results are satisfactory, if other construction work is to be done, the surface of the locking parts of the product is covered with protective caps.

The best siphons for shower trays

If you are installing a shower tray, there is very little free space between the outlet and the floor, so compact, low models will be appropriate. Consider the fact that the diameter of the shower drain must have increased throughput. Therefore, the parameters will be specific. Vyborexperta.ru recommends 2 nominees, leaders in positive reviews.

Criteria for choosing a dry siphon

In order to prevent mistakes when choosing a shutter model in a particular case, the following factors must be especially carefully considered. The main conditions of which, when choosing, should be the following:

A fairly important indicator for choosing the required dry seal for sewerage is the amount of waste that will pass through it. For example, a dry shutter with a passage diameter of 50 mm is well suited for a washbasin. For showers or baths, valves with a larger throughput capacity will be required. In such cases, it is necessary to purchase a device with a passage diameter of 100 mm.
The second condition that must be taken into account is the height of the device. Horizontal bends, as a rule, have a height of 7 to 10 cm, while vertical bends require more free space (about 15-18 cm). Therefore, if you do not want to carry out installation in cramped conditions, it is best to choose a horizontal model.

Helpful information! When purchasing this device, you need to pay attention to the little things. It is advisable to make sure that the device is working. This is done quite simply - you just need to pass a certain amount of water through it.

Don't forget about the appearance of the device. Shower drains, the design of which includes dry seals, can be equipped with a grate of any configuration. There are quite a lot of design solutions in this situation. This allows you to turn the device into a decorative product that will delight with its aesthetics.

The best siphons for a washing machine

The design of the units attached to the washing machine is distinguished by the presence of an additional outlet for the inlet pipe. The end here is predominantly threaded, fastening is done using a nut or under a hose. To simplify your search, VyborExpert offers 2 proven models.

Marking of plastic.

The most important thing during the installation process is to ensure that rubber gaskets are not forgotten or lost. They protect the structure from leakage of wastewater and guarantee long-term service.

How to make a dry shutter yourself?

In order to make this device yourself, you will need a plastic ball and a gasket. The ball should be slightly larger than the diameter of the drain hole.

A plastic ball must be placed on the drain hole.
After this, you need to secure it around the edges. The ball must be securely fixed.
To accomplish this task, you need to put a gasket on the sewer pipe that will securely fix the ball in the pipe. The height of the wall above the level of the drain pipe should not be less than 5 cm.

When using the system, the ball floats and water easily penetrates into the drain. When the structure is inactive, the ball lies on the drain hole, thereby blocking the path of sewer gases.

How to choose a siphon

There are several criteria by which you can choose in absentia which siphon for a sink, shower tray/bathtub or washing machine is better. We recommend paying attention to the purpose of the unit, its design features, materials, drain mechanism, as well as the diameter of the connection and outlet.

Purpose

Structurally, such units also differ in purpose. For example, models with a drain and a non-return valve are suitable for a washing machine; flat products with an overflow are installed in the bathroom. In the kitchen, due to the frequent use of the water supply, units with an enlarged body are used, but under the shower tray, on the contrary, the most compact, low alternative is needed.

Design

Based on the type of construction, a distinction is made between horizontal and vertical systems. If direct pipe installation to the floor is planned, the second option with good throughput without the risk of congestion is appropriate. Horizontal systems are universal, that is, for any room where the sewer system has a slight slope.

Material

Most often, siphons are made of plastic, polypropylene. Thanks to this, manufacturers reduce the cost of production. Such threads cannot withstand strong tightening, as they may burst. Products made from brass and stainless steel are more reliable and attractive; they are durable, but require additional costs to purchase.

Drain mechanism

According to the principle of operation, siphons are divided into 3 types:

automatic - click-clack, where the cover on the pin prevents water from entering the pipe or units with a special handle and cable placed on the cover to monitor the flow of water;
semi-automatic - a similar operating mechanism, but it requires physical effort by pressing the pin to drain the water;
manual - the simplest design; drainage here is performed by lifting the lid to reveal the drain.

Click-clack is convenient in tandem with the bathtub. The remaining models are universal, they adapt to different tasks and purposes of use.

Connection and outlet diameter

One of the important selection indicators is the thread size of the pipe with which the product is connected to the plumbing fixtures. It must correspond to the diameter and pitch of the installation location. The second edge of the housing, which is attached to the sewer, must correspond in diameter to the collector tee.

Sewer drain with dry siphon

Installation of this design is carried out in rooms where drainage occurs from the entire floor surface. During construction, a sealed floor screed is installed, in which a siphon is installed to prevent air from entering from the sewer.

But in the case of a sewer drain in a bathroom or bathhouse, it is necessary to take into account long-term downtime of the room, which is especially true for shower rooms in bathhouses. In such situations, when the water in the seal dries out, air with an unpleasant odor from the sewer easily penetrates into the room.

Because of this, in addition to the water seal, a dry siphon is also installed in baths and bathrooms. It is not a special device, and its installation is carried out as part of the sewer drain structure. This valve allows you to block the lumen of the pipe even without water.

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.

Types of siphons according to the method of drainage control

The siphon for the tray is part of the drain design. There is often a need to leave some water in the pan. To do this, close the outlet of the siphon.

There are several options on how to do this:

using a cork;
using a lever;
by pressing the button.

Let's look at all drain control methods to understand how they work.

Cork as a control mechanism

The most primitive elementary option is a design with a plug. This outlet is not equipped with any valves; the water simply leaves the pan through the hole and goes straight into the siphon. To collect water, the drain hole is closed manually using a plug.

This design does not present any complexity. This technique is familiar to everyone, because it is used in ordinary bathtubs and sinks. In modern shower stalls, ordinary drains are used less and less.

Tray siphons, in which the drain hole is closed with a plug if necessary, are in little demand. They are being replaced by more convenient models with a button

The concept of a “drain plug” will soon completely disappear from everyday life; it will be replaced by new automatic devices.

Drain control using a lever

An outlet with an automatic bottom valve is much more convenient than a conventional “plug” system. There is no need to constantly look for this same plug; the hole closes automatically when you turn the lever.

The design is quite simple; the lever is usually located in the mixer area. The valve and mixer are sold and installed together, which is not very convenient.

Turning the valve leads to partial or complete blocking of the drain hole. This system is convenient because there is no need to bend over, look for a plug or immerse your hand in water.

Click-clack button for water release

Separately from the mixer, you can purchase an automatic drain valve of the Click-clack system, also known as Push&Open. The valve is a large button that can be pressed with your foot.

The push-button flush system is easy to use, looks stylish and doesn't require you to dip your fingers into dirty water to release the water, as is the case with a plug.

When pressed once, the drain closes, when pressed again, it opens. Using such a device is as easy as shelling pears, and its installation is much easier and faster than an automatic lever valve.
