What is a diverter in the mixer

Every mixer is a sophisticated contraption made up of different components. Among them is a diverter, an element that deserves closer attention since not everyone is familiar with its purpose.

What in the mixer is called a diverter

The diverter functions as a specialized node to divert the flow of water to the appropriate pipe, either to the showerhead or mixer. The proper operation of this component is critical for controlling the flow between the showerhead and hose.

The switch mechanism incorporates a specially designed crank that facilitates the movement of the barrel and valve. Additionally, a rod and rubber gaskets are utilized within the mechanism. By adjusting its position, one can selectively open one of the two spigots.

Regrettably, the diverter is often considered the "weak link" in the mixer, and is usually the first component to sustain damage.

There are several possible causes for its malfunction:

• wear and tear of gaskets;
• corrosion.

The reason for the latter is the improper fit of the valve, resulting in water leaking into both connections simultaneously. This leads to leakage in the mixer. Nevertheless, any component of the diverter can be easily replaced. However, it is important not to overlook the lifespan of the faucet. If you have been using it for an extended period, it may be more suitable to replace it entirely rather than repairing it.

There are numerous types. Now, we will go into great detail about each one.

Button

The traditional version of the diverter in the mixer, which is widely favored by customers. When there is high pressure in the pipeline and automatic switching is not possible, a push-button mechanism can be installed. To alter the flow direction, simply raise or lower the lever. Because of this functionality, the push-button mechanism is also known as an extractor. Both manual and mechanical variations are available.

Lever or flag

Additionally, there is the possibility of utilizing a rotary diverter. This type of diverter is known for its straightforward and uncomplicated design. By simply turning the handle, the direction of the flow can be effortlessly adjusted. This particular mechanism is typically installed in mixers that are equipped with two handles.

Typically found on a two-valve mixer, the spool mechanism boasts a simple design that allows for easy replacement or repair without the need for professional assistance.

Cartridge

There is only a single lever, which controls both the pressure and direction of the flow. The downside of this design is that the mechanism cannot be repaired, so if it malfunctions, it must be replaced with a brand new one.

Eccentric

A ball diverter, also known as a diverter valve, can be controlled by rotating the handle to activate the stem, allowing you to open or close the desired faucet.

This mechanism is known for its simplicity and easy repair. The most common issue is the failure of the rubber gasket, which can be seen as an advantage as it is easily replaceable. However, in case of a major problem, the entire mechanism needs to be unscrewed for repairs, which can be time-consuming and challenging.

Due to its lack of operational convenience, this type of diverter is not widely used. However, one advantage of this diverter is its ease of repair.

Diverters can be classified into two types based on their functionality:

• Two-position diverters
• Three-position diverters

The first type is more affordable, making it more popular. The second type is more complex and is commonly used in kitchens.

There are also different types of diverters based on the installation method:

• Built-in diverters
• Separate or stand-alone models

From what the diverter is made

This mechanism is composed of different alloys or metals. Among the most popular ones are aluminum, brass, and silumin. There are also occasions when ceramic models are used.

Unfortunately, silumin has a major drawback – it is prone to rapid corrosion. Because of this, its lifespan is short. The aluminum and brass alloy is also not known for its durability, making it a more affordable option.

The reason behind this is that lead is added during the manufacturing of such products, but its wear resistance and durability are not ideal.

The corrosion process in mechanisms made of silumin or metal alloys occurs due to fluctuations in water temperature.

If we consider products crafted from pure brass or aluminum, these are among the most durable and high-quality diverters available. However, one downside is that they are prone to lime scale buildup when exposed to hard water. On the other hand, diverters with a push-button mechanism tend to have a longer lifespan compared to those with a lever-type mechanism.

Ceramic diverters consist of a metal base coated with chrome, with ceramic plates making up the shut-off system. This material is able to withstand mechanical impact, resulting in an exceptionally long service life. Some models even come with a warranty of over 45 years, highlighting their durability and reliability. Additionally, ceramic diverter can withstand hydro-impact and other loads that can easily damage silumin or alloy diverters. Despite their high quality, ceramic diverters may be more expensive than their counterparts.
