Why isn't the toilet tank filling with water? What causes sewer odors to back up?
Sewer odors may be due to the floor drain, not the deodorizer. There are many floor drains of varying quality on the market. When choosing a floor drain, it is important to choose one of good quality with a complete deodorizing function.

Ventilation Equipment Installation Standards
Piping and fittings from the closed valve to the project mouth of the ventilation equipment should be welded using 2-3mm thick steel plates, and the welding should be sufficient, uniform and tight. Ventilation pipes in toxic areas should be connected by welding. Ventilation pipes and closed valves should be connected by flanges with closed grooves, and smooth contact should be maintained; flange gaskets should be made of full-circle non-interfacial rubber sealing rings.

In drainage systems, a water seal is a device that allows wastewater and sewage to drain smoothly and freely. The gas passage is sealed by a water column, preventing sewer gases and harmful or toxic gases from escaping into the room. A trap is a pipe fitting that acts as a water seal device. Traps are installed at the outlet of sanitary fixtures or within the structure of the sanitary fixtures themselves (such as in bathrooms). If the water seal of a sanitary fixture's trap is damaged, it can cause the fixture to bubble, overflow, splash, and release harmful and toxic sewer gases, affecting both usability and indoor air quality, and endangering people's physical and mental health.

The principle and function of building negative pressure systems
Building system negative pressure, also known as a unidirectional fresh air system, works by using a high-power motor to forcefully exhaust stale indoor air through an exhaust outlet. This creates a negative pressure environment inside the building. To balance atmospheric pressure, outdoor air is forcefully drawn into the building through window and door gaps or dedicated inlets, creating a complete indoor ventilation system.

Function and control principle of building negative pressure system
Air quality control of fresh air units refers to controlling the temperature and humidity of the air delivered by the fresh air units to satisfactory setpoints, and installing temperature and humidity sensors in the building system's negative pressure. On the air ducts, the coil water valve is switched on or off according to the supply air temperature to ensure the set supply air temperature.

What are the functions of a building's negative pressure system?
Building system negative pressure system is a "forced exhaust, natural inflow" ventilation system, which only installs a central fan in the exhaust system, using the negative pressure principle to drive indoor air flow. Fresh air enters the living space, and dirty air is discharged from the bathroom.

Why are building negative pressure systems more suitable for residential use?
Building system negative pressure refers to the continuous removal of indoor polluted air to the outside by a silent fan, creating negative pressure inside. According to the principle of atmospheric equilibrium, fresh outdoor air is directly introduced into the room through wall-mounted or window-mounted air inlets, keeping the indoor air fresh and clean.

Ventilation Equipment: How to Improve Indoor Ventilation?
How to improve indoor ventilation? A reasonable suggestion is to install mechanical ventilation equipment. Through this, we can ventilate without opening windows, allowing fresh outside air to continuously enter the room and continuously expelling the original polluted air, preventing excessively high carbon dioxide levels indoors. Ventilation equipment also has multi-layer filters that can effectively filter pollutants such as dust, pollen, viruses, exhaust gases, and smoke from the outside air, ensuring clean indoor air.

How to choose the right ventilation equipment for you
How to Choose Suitable Ventilation Equipment1. When choosing ventilation equipment, factors such as family size, population, climate conditions, and environmental pollution should be considered. 2. If only two people live in a friendly place, then a ventilation volume of 60 cubic meters is sufficient, and an economical method is a natural valve or ventilator.

Why is it necessary to install ventilation equipment at home?
The purpose of indoor ventilation equipment is to deliver fresh outdoor air into the room. Previously, outdoor air was relatively clean, and it entered the room through window cracks or by frequently opening windows for ventilation. Now, outdoor air pollution is quite serious, and the windows of indoor rooms are basically closed. Thus, a new problem has arisen: the dust, smoke, and noise outside make opening windows for ventilation unrealistic, while the stuffiness and lack of oxygen when windows are closed affect healthy breathing. Indoor ventilation equipment is a solution to the above problems; it can deliver fresh air into the room, allowing the room to maintain effective ventilation even with the windows closed.
