Plumbing codes do prevail though. With the possibility of metals, oils, anaerobics in suspension, this discharge must go to sanitary. We put 2x2.5 NPTxNH adapters on all our testing accounts outlets that exit the building and hose to sewer, even 3” drain risers. Homemade ‘hosemonster’ style diffusers suspended down on ratchet straps keep them up and away from the turds and from splashing on the street. Unfortunately inside tight drains, with or without sight glasses or air gaps are a thing of the past. ASPE member since 1979.
TD Notwithstanding applicable plumbing codes the sewage authority has restricted sanitary to effluent from sinks, water closets, lavatories, dishwashers, showers requiring biological treatment, ie grey and black water. The idea is to reduce outfall from sources other than above.

The p-trap would also be required to have a trap primer also as mentioned earlier. Jeff Bridges JBFP Inc
