The distance of a vent from a trap seal typically depends on local Plumbing codes and regulations. Generally, the vent should be installed within a certain distance from the trap to ensure proper drainage and prevent siphoning of the trap seal. This distance is often around 4 to 6 feet for most applications, but it's essential to consult specific plumbing codes for precise requirements. Proper venting is crucial to maintain appropriate air pressure and prevent odor issues in plumbing systems.

Should the trap be before or after vent?
Depends on your perspective what is before or after. If you're following the direction of the water flow, the trap needs to be before the vent. A water filled trap blocks bad smells/dangerous gasses from entering your home. Putting the vent closest to the sink would bypasses that block. It would also likely cause gurgling because of siphon action trying to pull the water out of your trap (the vent breaks the siphon because its easier to pull air down the vent than to remove the water from the trap) Right = Sink - trap - vent - main drain stack
What is the proper way to run a condensate drain with a trap Does it need a vent?
The condensate drain on the a-coil should have a trap and the trap should be vented for proper operation . The vent should rise above the top edge of the drain pan in the unit. Their should be a capped clean out before the vent.

What is the maximum distance of a water closet trap from a vent line?
toilet should have a vent with in three feet of down pipe, but as long as you are with in the drop range for hori. pipe run you can go as far as you want, but you need that air vent close as you can so that the suction from the toilet water does not pull the rest of water from toilet base(p trap).

Should the trap be before or after vent or condensation drain?
The trap should be before the vent. The trap is used to maintain a watter barrier to prevent waste water and sewer gasses from entering the home. The vent is use after the trap to allow the water to flow freely in the pipe with out drawing the water from the trap.

Is the pee trap above or below the vent?
I BELIEVE: In a horizontal run, the p-trap must be below the vent. Otherwise, the vent may fill with water, creating a blockage, which would then syphon the water from the p-trap causing odors and health concerns from sewer gas. On a horizontal run, the vent must come off the run (presumably with a "wye") where the vent run is above the center line of the drainage run, thus the p-trap is lower than the vent...
How close to trap should vent be on a water closet?
The vent for a water closet should be installed as close to the trap as possible, ideally within 6 to 10 feet, to ensure proper drainage and prevent sewer gases from entering the home. Additionally, the vent should be positioned above the flood rim of the fixture to effectively allow air to flow into the drainage system. Proper venting helps maintain the water seal in the trap and ensures efficient waste removal. Always consult local plumbing codes for specific requirements.

How come gas doesn't come back up in the toilet?
Gas in the sewer line is prevented from coming back up into the toilet due to the water seal in the toilet's plumbing trap. This water seal acts as a barrier to block any gases or odors from entering the toilet bowl. Additionally, there are vent pipes in the plumbing system that allow gases to escape through the roof of the building.
