Air valve for sewerage - a reliable remedy for various troubles

Many of those who have heard about the 50 sewer air valve are probably wondering what it is and why it is needed at all. In fact, this is a very necessary device for every home. Therefore, we will talk about it in our article.

Properties

It is rather difficult to imagine a toilet (or bathroom) without any foreign smells. This creates a certain discomfort, in connection with which an air check valve for sewage was invented. It allows you to deal with many problems.

Causes of odor

Surely many people are wondering where this unpleasant smell comes from. Of course, when there is a blockage of the highway, then everything is clear. However, what if it doesn't exist?

In fact, everything is quite simple - the reason is the simultaneous drain from several devices. As a result, a vacuum of air appears in the pipes, and it is able to squeeze out all the liquid from the valves. As a result, air moves freely throughout the system, and with it some stench.

Previously, when the air valve for the sewer had not yet been invented, there was only one solution to such a problem - the ventilation of the riser to the attic (or roof). At the same time, such a measure did not give proper efficiency, because at low temperatures it froze and did not cope with its task at all. Fortunately, the product described by us came to the rescue.

Device and principle of operation

The instruction below will explain how such a mechanism () works.

It consists of the following elements:

• Stock. This is the main structural element that opens (and closes) the side opening if necessary.
• Case with holes located on the side. They are needed for air intake. In most cases, this element is made of plastic, because the price of such a material is the lowest, but there are other options.

Tip: PVC is resistant to moisture and most chemically aggressive substances, but is very afraid of mechanical stress (it is easy to break). Therefore, some people purchase metal counterparts that have a longer service life.

• Rubber gasket. It is needed to ensure maximum sealing of the device.
• Protective cover.

In most cases, these mechanisms are available in two sizes: 110 and 50 mm (for connecting individual elements). However, today you can find others, for example, the sewer air valve 100. This is due to the fact that now there are countless different plumbing equipment, the dimensions of which may be non-standard.

The principle of operation of the product described by us is as follows:

• When draining from several devices, a vacuum is formed in the system. This means that the pressure first rises sharply, and then also rapidly decreases.
• If the common pipe does not ventilate, then the rod slightly opens the hole located on the side. As a result, some air enters the riser.
• When the pressure in the system returns to normal, the device assumes its original position.

As a result, this, simple at first glance, the product provides pressure control throughout the line. As a result, unpleasant odors from below do not get outside.

Varieties

Now in stores you can find several varieties at once:

• Air automatic. It has a rather weak bandwidth, so it is used only in the private sector. Provides only air release.
• Anti-vacuum. Used for any number of pipes. Provides both exhaust and air intake.
• Combined.

If funds allow, you can safely take anti-vacuum even for one private house. This will ensure maximum efficiency.

Two words about installation

If this is the first time you are going to work with such a mechanism with your own hands, then you probably want to know how it is connected.

Actually there are two options:

• We install one valve directly on the common riser, which is responsible for all the air in the system. It is mounted using various fittings (they are selected depending on the material and shape of the pipes). In this case, purchase a product with a diameter of 110 mm.

Important! Do not forget to treat all joints with sealant (it is better to use silicone samples).

• If you want to achieve maximum efficiency, you can install it separately for each plumbing fixture (toilet, sink, bathtub, washing machine, etc.). In this case, a diameter of 50 mm should be preferred.

Benefits of using such a device

Now let's figure out what the sewer air valve gives.

It is worth saying that this device has several functions:

• Neutralization of an unpleasant smell. We have already talked about this, and once again we note that this is the main function of such a device.
• Saving. The fact is that when laying sewers, it becomes necessary to install a reverse type highway. If we use the valve described by us, then we can neglect such a costly procedure.
• Facilitate work. It does not have to be installed on the roof. Sometimes this turns out to be a very problematic procedure.

• Increasing the efficiency of the highway. If the house has a relatively large number of plumbing elements (at least 5), then the presence of such a device is simply necessary. Otherwise, the sewage system will not cope with the task.

Conclusion

Now you will certainly be able to choose the 110 sewer air valve that suits you. However, if you could not understand all the subtleties, then do not be discouraged ().
