Issue:
From furnace - One 3/4" PVC with an inclination goes into a condensate pump.
From AH - One 3/4" PVC with an inclination goes into another hole of a condensate pump.

Issue:

From AH - One 3/4" PVC with an inclination goes into another hole of a condensate pump.
Inspector demanded:
- The furnace drain must have a trap with air venting.
- The furnace drain must have a acid neutralizer before discharging into the condensate pump
- The AH drain should also have a trap with air venting.
- The AH vent can be tied into the furnace drain however tie must happen before the acid neutralizer
- the AH has a 2nd. drain port (slightly higher) it must also be EITHER drained into a different completely location OR it must have an alarm/sensor which switches off the furnace if water's detected
HVAC person said:
- These drains have positive pressure and traps are NOT required.
- He agrees w.r.t. neutralizer but said there's no law/regulation/code in New Jersey but its "good to have". He said if there was one - you'll find crappy neutralizers appearing in stores like the big orange dime a dozen.
- The AH drain doesn't even need a neutralizer
- He has been never asked to introduce plumbing for the AH secondary drain or be forced to introduce an alarm/sensor.
Please help!
