Check valve for sewer, photo, device, installation, reviews. Check valve for Sewerage their hands

The Owners of first floor apartments often encounter problems when sewage flooded the home. Fluid from the system quickly spreads through the premises and causing material damage. To eliminate such troubles, you can use a check valve on the drain. These devices prevent the return of wastewater to the apartment. However, before purchasing such a product, it is important to familiarize yourself with the features of the erection works.

Reviews about valve

As suggested by users, for normal operation of the system requires that the sewage went through the pipeline with a certain speed. The movement is provided by a bias which must be included in the regeneration system. If it decreased as a result of subsidence of the Foundation or initially was insufficient, the speed of movement of wastewater in the process of operation may slow down. Here lies the main reason for the clogging of sewers, which is expressed in the wrong slope outlet pipes. While coarse particles will settle on the walls, because the force of water movement won't be able to influence them with that intensity, which would be enough to move the masses. At some point in time, the deposits will block the gap of the pipes.

Using incorrect installation system

As emphasized by the user, the same happens in the case when the slope is too steep, the water does not have time to deal with the waste. The check valve on the sewage system may be needed in the case when the pipeline was worn. This occurs during long-term operation of the system within which deposits form. The clearance inside is less, and subject to normal speed drains the large particle items will be fixed on the walls. They gradually accumulate, acquire hardness, and form a clog. Home masters have noted that the need to install the described item may be required in the case where horizontal offsets are set at right angles. These nodes change the configuration of the pipeline, whereby the speed of movement of the effluent is lost. Regardless of whether it slows down or speeds up, it negatively affects the system operation, which becomes a cause of formation of blockage.

Installation Guidelines

The check valve on the sewer are set on a particular technology. Before you start installation work, you must determine which place will be the host, it's important to consider the provision of open access for maintenance and cleaning. When choosing a model, it is necessary to be guided not by the low cost and quality characteristics, because the cost of the valve must not be compared with the cost of repairing the apartment, when it will be flooding with sewage. The master must pay attention to the technology of installation of equipment.

Most often, these devices are universal, however you can find models that are intended only for vertical or horizontal installation. The check valve on the sewer prior to Assembly checked for leaks. For installation you should perform a cutout of the required size in the pipeline, and then make the valve pipe. If the sewer system is made on the basis of cast iron, it will install the adapter with the metal on the plastic. The mounting element is carried out in accordance with the direction of fluid motion. On each unit there is an arrow that points in this direction. It should be directed towards collector.

Technique works

Non-return valve for sewage, a photo of which you can see in the article, may be installed on separate hardware or on the entire sewer system as a whole. In the first case we are talking about the sink or the toilet. If you have lift check valve, the Assembly is performed exclusively in the horizontal section of the sewage system. Before you start work, you need to pick up the equipment. The choice should be based on the characteristics of the system, for example, the volume of wastewater. Among other things, select the device, allowing the installation location of the device, it can be the whole system or a separate node.

Before you install a check valve on the drain, you need to choose a place in front of the General sewer riser. If work is carried out over the existing system, in a certain place of it is cut a certain plot that will conform to the dimensions of the valve. If is the arrangement of the whole Sewerage system, the equipment is installed in the correct location. The next step is to check the tightness of the device.

Setting the reverse vent valve on the sewer

Non-return valve for sewage PVC can be designed to counter the extraneous noise and unpleasantsmells. Such a device is called aeration valve and is determined based on the fitting. Initially, the master must choose a location for mounting that will depend on the necessary aeration of the entire sewer system, or individual host. In the latter case the valve is installed with a deviation of 30 centimeters from the gravity pipes. From the nearest trap element you want to remove 20 centimeters.

Nuances

In the first case, products are installed in a dedicated room or in the attic. Install the check valve on the sewer is conducted according to the principle of fixing to the pipe with a fitting or a thread. At the final stage, you need to analyze how the joints of the device with the tubes sealed.

Reference

To ensure correct operation of the appliance, it is important to ensure the temperature of the air which should not be less than 0 degrees.

Device check valve

Non-return valve plastic for water drain has certain design features. You can find devices of this type, which consist of a housing made in the form of a tube segment. Inside is a locking plate, which is equipped with a rubber gasket. To it is fixed a spring, made of stainless steel. The valve body has a removable cover, which allows cleaning from the inside that you may need if dirty. Casing is a lever with which you can open or close the valve manually. If it is in the closed position, the locking plate is stationary and while it does not pass water. If it is open, then pass through sewage. The effluent leaving the apartment, rushing to the sewer standpipe and raising the closure plate. Once draining has been completed, the plate is returned to its place by spring. If there is reverse current of the sewage, this element will not miss them in the home.

What else should I know about the design features?

Dish has a diameter that is greater than the specified value of the limit, this ensures the reliability of the neck of the valve. If you are interested in the device non-return valve for sewage, it is possible to consider another variant, which has a smaller diameter. Such a device is the location of the outlet and the inlet tube is different. Between these two elements is air which presses on the membrane of the outlet pipe, it is the reverse flow of water. The membrane is required to close the nozzle, which eliminates the flow of water in the opposite direction.

Is it Possible to manufacture the valve with your hands?

Non-return valve for sewage with their hands it is possible to install yourself, but to make such a mechanism impossible even for the specialist. Such nodes are carried out in the factory using special technology and equipment. For example, the simplest model is composed of a diaphragm valve, a lever and a removable cover. The last element necessary to clean the device when clogged. If you do decide to engage in the manufacture, the process works, you can use brass, bronze, stainless steel, cast iron and plastic.

Wafer check valve can be manufactured on the basis of the membrane, which is represented by a disk. Instead of a lever you can use the spring. If you decide to perform a double-wing valve, then the membrane should be made of two folds. In the presence of a sewer pipe minor diameter you can run a ball valve which has a membrane in the form of a ball and the lever-spring. This kind of device is considered the most reliable and common. To replace or service the device, the valve need to be dismantled, the wizard will not face particular difficulties, as its installation is two bolts.

Reviews about check valve

Check valve for sewer, reviews about which you can read below, can be designed for external and internal sewer systems. According to users, making this node is not recommended, as incorrect operation can adversely affect the operation of the entire Sewerage system. The buyers claim that the high-quality valves have a mechanical strength, reliable connection with the main trunk, as well as resistance to aggressive media.

Mechanical strength is extremely important for the reason that whole section and the surface of the valve exposed to the external pressure of the soil. This is true for sites that are designed for external Sewerage system. But resistance to an aggressive environment needs to have valves for external and internal systems.

Buyers say that it is important to establish and aeration valve which would preclude the passage of odors through the internal wiring. If you don't want to hear other sounds that occur in the plumbing fixtures, install a check valve.
