Single lever mixer: the best manufacturers + instructions for disassembling the tap

For many decades, sinks and washbasins have traditionally been equipped with two-valve taps.However, recently in kitchens and bathrooms you can increasingly see a more modern plumbing accessory - a single-lever mixer, attractive for its practicality and ease of use.

You will learn everything about choosing a lever mixing device from our article. We will talk about its design features and operational advantages. Do-it-yourself DIYers will find a guide on how to disassemble and repair a kitchen faucet of this type.

Design of single-lever models

A distinctive characteristic of this type of mixer can be considered a lever that simultaneously performs the functions of two heads at once. With its help, the temperature and pressure of the supplied jet are regulated.

In the first case, the tap handle moves to the right or left, in the second - up or down. Usually these processes are combined, allowing the user to set the option that is most comfortable for him.

The design of single-lever accessories is extremely simple. Typically such a device consists of the following parts:

• frame - can be made of different materials;
• spout - depending on the purpose of the tap, it can be low, high or medium-sized;
• switch — a lever with which the temperature and flow strength are set;
• cartridge — to regulate the flow of water, which is an analogue of a faucet axle box.

In addition, single-valve devices also use service elements, such as gaskets. Often such accessories are also equipped with additional components that increase comfort of use. Among them aerators, saturating the flowing stream with air, built-in dispensers for detergents and much more.

Single lever faucets can be made from a variety of materials. Chrome-plated models have become especially popular, but on the market you can also find accessories made of copper, brass or granite imitation

Locking element options

IN single lever models Two types of units that regulate water flow can be used. Let's take a closer look at their device.

Ball lever

Such a unit is a ball made of stainless steel, in which special holes and fasteners are provided, with the help of which the sleeve with the ball located inside is attached to the structure.

When the lever is turned, the holes on the ball move, blocking or clearing the path for the movement of cold and hot water, thereby regulating the temperature and flow pressure.

Lever valves with a ball mechanism are perfectly resistant to water hammer.

However, such models have a number of disadvantages, which include:

• relative high cost;
• rapid accumulation of scale on the ball element;
• intensive wear of rubber gaskets.
• the complexity of repairs, which is why it is often necessary to dismantle the old and select a new faucet.

Due to the listed disadvantages, mixers of this design are used less and less in everyday life and in production. Unlike them Ball Valves, installed in front of plumbing fixtures on water supply pipes to control the water supply, have almost completely replaced valve models.

Disc crane models

Such accessories are favored by consumers and specialists. The operating mechanism of such mixers is ceramic disc cartridges, similar to ceramic disc mechanisms that are used in two-valve devices.

The disk mixer, a schematic representation of which is shown in the figure, is considered a more practical functional model, since it allows cartridge replacement

Externally, this element looks like a plastic cylinder, usually blue. However, hidden under the body are two plates made of snow-white, carefully polished ceramic. One of these disks can move depending on changes in the position of the lever.

In order for water to flow into the spout, the holes on the upper and lower parts must match. If this does not happen, the flow is blocked and does not enter the tap.

Disc models have a number of advantages:

• moderate cost;
• opportunity replacing cartridge elements, which makes repairs easier;
• reluctance to form scale, which hardly accumulates on ceramic surfaces.

The weak point of such structures is their sensitivity to foreign inclusions in the water flow, as well as to sudden pressure surges in the water network.

The cartridge discs are made of well-polished ceramic, which ensures a good fit. The service life of mixers largely depends on the quality of these parts.

How to disassemble a lever device?

To repair models with one locking mechanism, it is necessary, first of all, to disassemble the structure in order to remove the damaged element. It is replaced with a similar new part. Lever mixer repair It is quite easy to do, but you need to act very carefully.

Disassembling a disk product

To dismantle the accessory, you will need a set of the following tools - a screwdriver and a hex key.

The following algorithm of actions is used:

• First of all, you need to shut off the hot/cold water pipes.
• You should free yourself from the plug, which can be removed with a screwdriver.
• Using a hex key, unscrew the screw part that connects the lever to the rod, where the water is regulated.
• Having done this, you can manually remove the crane lever. Then you need to unscrew the ceramic nut, as well as the clamping nut that secures the top plate.

This allows access to the mixer disc. You can take it out and insert a new cartridge into the resulting space, but you need to ensure the correct position of the holes on this part.

After which all operations are carried out in reverse order. Having assembled the faucet and completed the manipulations, you can turn on the water to check the correct assembly.

When going to the store to buy a new cartridge, it is advisable to take the failed disk. Models may differ in the diameter of the holes available and the fasteners located on the bottom edge of the products.It is better to give preference to cartridges with a silicone gasket, as they are better resistant to water.

Disassembling the ball mixer

A similar process is performed in the same way as described above, but there are some nuances. First of all, you also need to turn off the water. After this, using a screwdriver, the decorative plug is removed, the fixing screw is unscrewed and the nut that holds the faucet mechanism in the correct position is removed.

It is worth keeping in mind that if the ball accessory is seriously damaged, the entire mixer will have to be replaced. Ball device repair This is only possible if the problem is caused by a worn out rubber gasket or the tap being clogged with abrasive materials.

In some faucet models, the handle fits quite tightly into the control rod. To release the part, it is recommended to carefully pry it off with the end of a screwdriver.

Constantly dripping water from the faucet usually indicates problems with the gasket.

To resolve the issue, you need to take the following steps:

• As described above, the screw is unscrewed and the lever is removed.
• The connection is removed from the thread, after which the screw is unscrewed with a screwdriver. If plaque is found on it, it must be carefully removed with a soft cloth.
• The ball is removed from the structure, after which the worn gaskets are carefully removed and replaced with new parts.
• Upon completion of the process, the ball is put back in place, and the seals are attached using a plastic nut.
• The lever is placed again, and then the screw that secures this part is screwed in.

After completing these operations, the crane is checked.

Problems with the ball mixer being clogged are indicated by a thin stream of water even with the tap at maximum pressure.

In this case, you need to follow the following instructions:

• unscrew the nut from the mixer spout;
• remove the mesh and rinse it thoroughly with water;
• insert the part back, and then re-tighten the nut.

If the manipulations described above do not help solve the problem, you need to replace the device and install a new mixer in the kitchen or bathroom.

Particular care must be taken when loosening and tightening the locking nuts. Excessive force can easily damage the elements.

Prevention of breakdowns of single-lever models

Since replacing a faucet is quite expensive, you need to think about simple preventative measures that can extend the working life of this important part.

These include:

• regular inspection of mixers to identify the slightest signs of leakage;
• installation of filtering equipment to improve water quality;
• elimination of high humidity in places where plumbing fixtures are located.

Before independent installation or dismantling, and even more so before carrying out repairs needs to be carefully studied mixer device and instructions and strictly follow the instructions. All connecting nodes must be sealed with special compounds or fum tape to avoid leaks.

The condition of the tap is positively influenced by the aerator, which mixes water with air. If the model does not have a built-in device, it can be purchased separately and installed on the mixer

It is also important to take a responsible approach to choosing models for the bathroom or kitchens. When purchasing a faucet, it is better to avoid silumin products made from an alloy of aluminum and silicon. Although such models are inexpensive, they quickly break down.

It is better to give preference to models made of brass, copper or chrome-plated steel, produced by well-established brands.
