Not where I really want to be
Left side is the line to the grease separator, right side is the house dwv which comes to a building trap.

The sewer authority has no written requirement for a whole building/house trap but the inspector in this town always makes them install one.

How would you handle this situation?

Note that Section 912.4.2 of the amendment indicates that a safe waste system MAY be used as an alternative to other waste systems required by code yet, Section 912.4.3 states that it SHALL be used.

Confusing eh?

I use to require standard running traps, but with low flow toilets they have become a problem. We have since not required them. All fixtures have traps and floor drains are primed. The excess gas will vent to the roof. To many clogs with the old traps.
 
Generally whole-house traps are prohibited on buildings connected to the public sewer so that the sewer can vent. We don't allow them when connected to the sewer. On a septic system we do not require them but will approve them if installed.
