Evaporation is the most common, syphoniage due to no vent or a block went is another cause or a leaking trap.
Same thing
By cutting it out and installing either a P trap or a running trap as an S trap is notorious for losing its seal
there are 100 inches in a trapseal
It is the shape of the drain. Lay a P down with the curve down and that is the basic shape of the drain. This keeps water in the loop if the P to make a seal against sewer gas coming back up.
A silt trap is a designated area where water that is contaminated with suspended sediment as a result of construction activity or water runoff is contained. While the water is in a silt trap, the sediment can settle to the bottom of the trap until it can be removed.
Same thing
fill it up with clean clear water to replenish the seal
Trap seal lost and foul air invading from drainage.
Just enough to reach the crown weir to prevent fumes from passing through the trap seal
toilets have a built in water trap And they should be properly vented to prevent trap seal loss
Trap seal loss occurs when you have poor venting and as one fixture drains it creates negative pressure created and it pulls the trap seal (water) from another trap and allows sewer gases to enter the structure
A p-trap is designed to hold water and form a seal so the toxic sewer gases cannot enter the house, named for its P shape
A P trap goes thru the wall, an S trap goes thru the floor.

A nani trap works by using water to seal open floor drains. A ring around the base prevents insects and odors from entering the room from the plumbing.
1. the water evaporates out of the trap.2. there is a leak in the trap connections ( only with some traps that have connections in the lower part of the trap.3. a suction force downstream of the trap pulls the water out of the trapTrap seal loss1- Capillary attraction2- Evaporation3- Back pitched4- Negative pressure (back siphonage)5- Positive pressure6- Crack / leak7- Oscillation
Check your flame trap first for a clogged trap.
