Where and why to install a sewer aerator 110
Sewer aerator 110 relieves residents from unpleasant odors and sounds when flushing from the toilet. Install the device on horizontal sections of the sewage system, auxiliary risers. Here is information about the devices and how to properly install the air valve.
The principle of operation of the sewer aerator
The internal sewage aerator primarily acts as a check valve, preventing liquids and gases from reaching the drain point. When using the toilet, a sharp flush of water lowers the pressure in the system, and if there is no valve, the liquid can return at a faster rate than it was drained. The sewer valve 110, when the pressure in the drain pipe drops, opens and levels the indicator.
- body;
- air intake;
- pressure regulation mechanism.
The body is sealed 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. Damper opening mechanism - rod or diaphragm. Membrane clogs less frequently.
A septic tank aerator is used to supply air to bacteria that decompose sewage. You can make it yourself, bring the pipe out of the septic tank, like a riser, and drown out at the top. Weld the inlet to the side for forced air injection.
Types of air valves
The sewerage wiring diagram is multi-level, has vertical and horizontal sections. It depends on the diameter of the pipes, the sustained slopes and the flow rate, which aerators for the sewage system are most effective. There is a system of aerators, each with a specification:
- the receiving aerator is mounted in front of the pumping pump on the horizontal section of the pipeline;
- ball model of aerator for plumbing fixtures with small pipe diameter;
- ball valve with a pressure spring;
- the wafer model is installed on pipes with a diameter of up to 20 cm, it can pass the flow or rotate 900.
Wafer models can be disc spring or double leaf. The actuator is a plate with a spring.
Air check valve with petal or rotary type actuator. This type of aerators for septic tank installed on pipes with a diameter less than 400 mm. For long sections where there is a risk of water hammer in the event of a spool rupture, damper valves are installed.
Valves are fastened by welding, clamped between two flanges with gaskets, or a threaded sleeve is used.
Reasons for installing air valves
The sewer system is dynamic. Costs are constantly changing, gases appear from the decomposition of sewage. Discharge through sanitary fittings changes the hydraulic regime in the pipes. Without regulatory tools, life, with a poorly functioning sewage system, becomes uncomfortable. Sewer aerator 110:
- automatically regulates pressure;
- non-volatile;
- protects the fan pipe from freezing in winter;
- easy 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 from two points on the same riser at the same time, the valve may not cope.
Sewer aerator 50 is installed on the internal sewerage system from spillway devices. Usually, such a device is used to equip the places of transitions from a 32 cm inlet connected to a 50 cm manifold. An air valve is installed on the horizontal section, cutting off the bad smell from the common pipe, equalizing the pressure in the system.
Correct installation of aerators
The air valve on the riser is installed in the attic, since 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 out 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 is impossible to bring it to the roof, providing the SNiP requirements for the distance to structural elements. When choosing a device, it should be taken into account that sometimes manual adjustment may be required. Install the aerator above the upper drain point in the system and must be accessible for inspection and repair.
The aerator only works when assembled correctly! The pipe and socket must not be interchanged,
Sewer aerator 50 can serve no more than two plumbing fixtures. Install the device no closer than a meter from the drain point. An aerator in the internal sewerage must be at the end of the network wiring, after the last device. The minimum distance from the floor during installation should be 35 cm. The device is mounted vertically.
A properly installed aerator will last a long time, but periodic checking of the valve condition is mandatory.
