What is a bottom valve in a faucet?

Unlike Russian citizens, Europeans take a more thorough approach to the issue of saving resources. They show real miracles of ingenuity when it comes to water consumption. For example, we have the people of Great Britain to thank for the foot valve. This product has an unusually simple design and at the same time is simple and convenient to use.

Despite the fact that the product is more common among Europeans, our compatriots appreciated its capabilities. But in order for the valve not to raise questions, it is necessary to thoroughly understand its structure, as well as learn about the advantages and disadvantages.

Bottom valve in the mixer: what does it mean?

The bottom valve is a miniature shut-off element that is installed in the drain hole of the sink in order to collect the required amount of water. Its appearance was caused by the fact that in a number of European countries there are no faucets that are familiar to us, and water comes from two separate taps. To mix the water and give it the required temperature, the British came up with a bottom valve.

Since we have standard faucets, the valve has found another use. It is most often used when it is necessary to wash small items by hand, shave or wash. When using it, there is no need to fill the basin or waste water. You just need to lower the shut-off valve, and after a few seconds the sink will fill with water.

Types of construction

Depending on the design, there are two types of device:

1. With mixer. A standard mixer is included in the kit along with the bottom valve. To install this structure, it is necessary that the plumbing equipment used has the technical capability. The device is controlled using a small lever, which is placed immediately behind the mixer or next to it.
2. Push open. It is sold separately from faucets, so it is not particularly popular among consumers. They are usually purchased if the old locking mechanism has failed and requires replacement, but the mixer remains operational.

The devices would hardly have become widespread in the post-Soviet space if some faucet models had not included them. Consumers quickly appreciated the benefits and ease of use, and shut-off valves can now be found in many homes.

Reference. One of the undeniable advantages of the product is that there is no need to make changes to the design of the plumbing fixtures.

In addition, valves can be either with or without overflow. Outwardly, this difference is invisible. Significant differences are hidden in their functions - models with overflow are safer: in the event of an emergency, excess water will flow into the drain rather than spill out onto the floor. If there is no overflow, even negligence or inattention can lead to serious consequences.

The standard package includes:

1. Cork. It is she who closes the drain hole.
2. Lever or spoke. With their help, the cork is set in motion - lowered or raised.
3. Kernel. It is necessary to connect the valve and lever.
4. Thread for fixing to a siphon.
5. Siphon. When fully assembled, the device is a complete system for regulating the drain.

Push open devices have a slightly different design. To open the valve, you must press it. Push open It has a simpler design, but it is not as convenient to use - to press the valve, you must immerse your hand in water. This is especially unpleasant if you have previously washed dirty clothes in the sink.

The advantage of these models is their attractive appearance. A small structure located at the bottom of the sink looks much more aesthetically pleasing than models with a lever.

Reference. Many Push open models have an attractive appearance, because they are made from brass or bronze.

Pros and cons of a foot valve

Consistently high demand and many positive reviews are due to a number of advantages that the bottom valve has. These include:

1. Economical. The constant rise in utility prices is forcing many to reconsider their approach to spending resources. The cost of the structure itself varies from 500 to 2000 rubles. This is a low price, which will more than pay for itself in reduced water bills.
2. Ease of use. All valve control comes down to pressing it with one finger. No special effort is required to raise or lower the device. Therefore, even small children can handle it.
3. Ergonomic design. The simplicity of the device makes it easy to clean it from dirt. In addition, the valve is coated with a special coating that prevents the accumulation of dirt. Therefore, you do not need to use special detergents to clean it.
4. Attractive appearance. A neat ceramic or metal plug looks much more aesthetically pleasing than a drain hole.
5. Hygiene. The plug prevents the penetration of unpleasant odors from the sewer.
6. Easy installation. The simplicity of the design allows it to be installed without the involvement of professionals.

The product has no serious flaws. However, several nuances must be taken into account:

1. When using, you must carefully monitor hygiene. To do this, the sink and valve should be cleaned regularly.
2. If you choose an option that does not have an overflow, keep an eye on the water level in the sink. Otherwise, the water will fill it completely and pour onto the floor.
3. Another irritating factor with Push Open models is having to put your hands in dirty water. The disadvantage of lever options is the inconvenient cleaning of elements located behind the mixer and under the plumbing.

Criterias of choice

Before buying, first of all, you need to decide on the cost, because it is extremely important to know what you are getting for your money. This parameter is influenced by the quality of materials and workmanship, the presence of additional functions, and design.

In addition, focus on the design of the sink. If it is not possible to drain excess water, then a device without an overflow is suitable. Alternatively, you can replace the siphon with a more practical model.

If you plan to wash in the sink frequently, it is better to opt for devices with a handle. Then you won't have to put your hands in dirty or hot water.

The bottom valve in the mixer can become both an indispensable assistant and cause trouble if it quickly becomes unusable. Therefore, when choosing, you should not save, but rather purchase a high-quality, stylish product that will last for several years.
