Where and why install a sewer aerator 110

The sewer aerator 110 relieves residents of the unpleasant smell and sounds when draining from the toilet. Install the device on horizontal sections of the sewer, auxiliary risers. Here is information about the devices and how to properly install the air valve.

The internal sewer aerator primarily works as a check valve, preventing liquid and gases from passing to the drain point. When using the toilet, a sharp descent of water lowers the pressure in the system, and if there is no valve, the liquid can return at a faster rate than it drained. The sewer valve 110, when the pressure drops in the drain pipe, opens and equalizes the indicator.

A schematic diagram of the operation of air valves is shown in the figure. All devices include:

• frame;
• air intake;
• pressure control mechanism.

The case is hermetic, with a removable cover. The connection must be threaded. There is a rubber seal between the parts.

The inlet should allow air to pass through, but not insects and rodents. The damper opening mechanism is rod or membrane. Membrane gets clogged less often.

A septic tank aerator is used to supply air to bacteria that decompose sewage. You can make it yourself, take the pipe out of the septic tank, like a riser, and drown it out at the top. Weld an inlet for forced air injection on the side.

Types of air valves

The sewerage layout is multi-level, has vertical and horizontal sections. It depends on the diameter of the pipes, the sustained slopes and the flow rate, which sewer aerators are the most effective. There is a system of aerators, each of which has a specification:

• the receiving aerator is mounted in front of the pumping pump on a horizontal section of the pipeline;
• ball model aerator for plumbing fixtures with small diameter pipes;
• ball valve with clamping spring;
• the wafer model is installed on pipes with a diameter of up to 20 cm, can pass the flow or turn 90.

Wafer models can be disc spring or bivalve. The actuator is a plate with a spring.

Air check valve with flap or rotary type actuator. This type of aerator is installed on pipes with a diameter of less than 400 mm. For long sections where there is a risk of water hammer when the spool breaks, damper valves are installed.

Valves are fastened by welding, clamped between two flanges with gaskets, or a threaded coupling is used.

Reasons for Installing Air Valves

The sewer system is dynamic. Costs are constantly changing, gases from the decomposition of sewage appear. Draining through sanitary appliances changes the hydraulic regime in the pipes. Without the instruments of regulation, life, with poorly functioning sewers, becomes uncomfortable. Sewer aerator 110:

• automatically regulates pressure;
• non-volatile;
• protects the fan pipe from freezing in winter;
• simple installation;
• low cost.

The device equalizes the pressure between the line and the atmosphere on the roof where it is installed. However, such a device can work effectively at a height not higher than the second floor. If a large flow is drained simultaneously from two points on the same riser, the valve may not be able to cope.

Sewer aerator 50 is installed on the internal sewerage from spillway devices. Usually, such a device is equipped with transition points from a 32 cm liner, which is joined to a 50 cm manifold. An air valve is installed on a horizontal section, cutting off the bad smell from the common pipe, equalizing the pressure in the system.

Proper installation of aerators

The air valve on the riser is installed in the attic, as it is frozen, it will not work. But the smell in the room should not be felt. If the house has several auxiliary risers and the main one is brought to the roof, then a sewer aerator 110 can be installed on others. This will significantly reduce costs. The device can also be used when the riser is not provided or it cannot be brought to the roof, providing the requirements of SNiP for the distance to structural elements. When choosing an instrument, it must be taken into account that manual adjustment may sometimes be required. Install the aerator above the top drain point in the system and must be accessible for inspection and repair.

The aerator only works when properly assembled! It is impossible to interchange the pipe and socket,

The sewer aerator 50 can serve no more than two plumbing fixtures. Install the device no closer than a meter from the drain point. The aerator in the internal sewer must be at the end of the network wiring, after the last device. The minimum distance from the floor during installation must be 35 cm. The device is mounted vertically.

A properly installed aerator will last a long time, but a periodic check of the valve's condition is a must.
