Default Re: AC condensate pipe into drain line

Definitely not. There must be an air gap--no direct connection. Or it can discharge outdoors, above grade. A common example is the drain going into the washing machine drain. Also, it appears as if the condensate drain is flowing uphill.

prosperity at any cost, safety first instead of duty first,
the love of soft living, and the get-rich-quick theory of life.”
