A floor drain (FWG) is a floor drain that can collect emissions from a number of devices, but connections are limited by the number of drains and spacing (see Figure 6).

This is the final valve for the sewer drains. It is located at the highest point of the culvert system. The goal is to release all the gas into the atmosphere. It is a mandatory part of the sewer system as the accumulation of gas from decaying organic matter can be very dangerous.
Floor trap is also called Nahni trap (Nahni means washing place / bath in Hindi). Nahni Trap is designed to prevent gases from entering the building through the seal. Regardless of whether the wastewater is flowing or not, the floor drain prevents the penetration of dirty gases (stench).
In DWV with gravity classification (drain, drain or vented), HxH is the classification of fittings that have a rod-shaped part at each end. H stands for hub. Fittings that have a bell section at one end and a straight section at the other end are classified as HxS. S stands for tap.
The purpose of a trap is to keep exhaust and possible pests out of the house. Back to S-traps - The reason S-traps are not allowed is because they have the potential to suck water from the siphon or filter as the water runs down the drain.
The siphon is the bend in the pipe where the waste exits the toilet. A strap goes to the bottom of the toilet and is designed to go through the floor where a trap exits the back of the toilet and goes through a wall.
Check the traps on the floor
A Ptrap takes its name from the combination of two 90 degree fittings with a horizontal overflow pipe and gives the whole the shape of the letter P. One of the 90 degree fittings protrudes from the sink and then contracts into another creating a system waterproofing is created to allow water to drain into the overflow
3 answers. All traps require ventilation in any case. Without ventilation, the water seal in the siphon is sucked in and the exhaust gas can enter the room.
A floor drain has a water tank to prevent gas from the sewer system from entering the room. It will also have an area where lighter objects can get stuck and pulled out.
When the room is full of water, each toilet will act as a drain. The water flowing down the drain moves the air into the pipes. Makes it impossible to breathe in the toilet.
The International HVAC Code (IPC) requires piping to extend vertically at least 6 inches (152 mm) above a roof, as specified in Section 905.5, Connections and Ventilation Levels. Also, the vent hoses should be at least 305 mm (12 ") long
each toilet must have ventilation, but they can be divided vertically or backwards. There is an accumulated load on the number of drains / drains so that you can have one or more roof passages.
In short, UPC wants the building’s sewer system to be well ventilated. A ventilation pipe with the same diameter as the building drain must therefore be separated from the drainage system and pass through the roof, regardless of its size. A popular way to meet this requirement is with a 3-inch or 4-inch vented toilet.
Plumbing vents are pipes that extend from drain pipes to the outside of the building and often go through the roof. Ventilation pipes ensure that exhaust gases can escape outside instead of being discharged into the house. The ventilation pipes also allow oxygen to enter the exhaust pipes.
