Offset??? Fill your Black tank to full with the water coming up the toilet tube. Shut off the water, open the Toilet to flush, let it close, Then start the Black flush again. Wait 1 minute, Then flush the toilet. Hope you have a rain suit on as the water will spray all over the bath and ceiling of the bath. ALL from that supposed 5 psi:B
Offset means the vent is large enough to handle the incoming flow RATE.
You’re completely confused when it come to water pressure. There is 45 psi available in the water system but flowing it into an open container doesn’t cause 45psi of pressure in the container. When it fills up, there is not much more than the static pressure of the water column rising in the vent. That is calculated roughly as 62 lbs (1 cu ft of water)/144 sq in. or a little under 0.5 psi per vertical foot. Now if there is a significant restriction in the exit (vent), higher pressure can build. That is how a garden hose nozzle works.
