All I said was code in my AHJ prohibits draining condensate into DWV plumbing. We require a dry sump outside of the foundation. I thought L.A. and the county were the same.

This is what I go by:

2021 CODE: 307.2.

Condensate drains shall not directly connect to any plumbing drain, waste or vent pipe. Condensate drains shall not discharge into a plumbing fixture other than a [exceptions] floor sink, floor drain, trench drain, mop sink, hub drain, standpipe, utility sink or laundry sink.

My take is that the discharge must enter free air before being collected. e.g., no closed direct to pipe connection. It's a health thing in case you can't figure that out.

I should have never brought this up. Do what you want.

Edit: A dry sump as determined by the local mechanical code is a 2 foot deep by something like 18" in diameter and filled with 3/4' stone/rock. This is a perfect breeding ground for the Aedes aegypti and Aedes albopictus mosquitos that invaded L.A. about 3-4 years ago and are a real health threat not to mention day biters. This goes to show you that building codes officials have always had their head up their ass when it comes to logic and reasoning. And why I dropped my licence and haven't pursued a permit for any work in 20 years. I go by the book when it makes sense but I don't deal with inspectors. Most are failed contractors and suck the hind tit.
