: A discharge line trap has important functions both during the compressor on period and during its off period. During the on period, the trap acts as a turbulator to entrain oil droplets and carry them efficiently up the elevated discharge line. Therefore, traps would be most useful in unloading or multi-compressor systems to better ensure proper oil circulation during low system loads. Also, you are required to change the size of the pipe after the "P" trap.

Why you U trap need at ahu?
U trap is used in the drainage line of ahu.it is used to keep water available in the u pipe even if there isn't any water to be drained.the reason behind keeping water in the line is to avoid the air from the drainage line to enter into the ahu by the presssure created by the blower.if it isn't there the blower will suck the drainage air and thus bad smell air would be passed to the room

Sewage line cheater vent?
Im not familiar with the term cheater vent. Perhaps you are referring to an Automatic Air Vent or Air Admittance Valve? They are installed per the manufacturers reccomendations. Some municipalitys around the US recognize these, but do not allow them. They work on the basis that once installed if there is negative pressure in the waste arm from the act of water being flushed through the p-trap and down the waste line they allow air to be entered into the system to protect the trap seal.

Yes. You need to open the plumb, & you have an air vent there.
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

Do you need an air vent installed for the dishwasher and garbage disposal and if so can it be installed another way if needed?
Your kitchen sink should already be vented if there is a p-trap draining to the wall. if it is an s-trap it is not vented and not to present code requirements. The dishwasher drain goes into the side of the disposal and the disposal should drain to the trap. A separate vent is not required for the disposal or dishwasher as the trap for the sink is what requires a vent.
Do you need and under sink air vent for a garbage disposal?

When you have a shower toilet gurgles water backs up what do you do?
Your drain line is plugged somewhere after your shower and toilet line are connected. The reason for the gurgle in your toilet is because air is trapped in the drain and your toilet is the closest place for air to flow to. If you had a vent on your toilet trap arm then it would gurgle in the vent rather in your toilet but your drain is still plugged and needs to be snaked out and maybe your drain line needs to be examined for right grade or broken.
