Thats pretty much common sense, right? Really? When doing load calculations (Manual J), we need to know how much of the heat load, especially the latent heat load, comes from leakage in the building envelope and the ducts. . That HVAC drain runs right beneath where the water heater is hanging, and the water heater condensate line is now hard-piped straight down and into the line so that the condensate runs outside without a trap or vent.

The most recent code is the International Mechanical Code (IMC). I have to imagine that with A/C being so much more common in the US, the only reason something similar hasn't been developed or adapted for use here is because it isn't allowed. Are there currently any plumbing codes that prevent A/C condensate from being used for toilet flushing? Check it periodically and clean, if necessary." Only the discharge of the condensate is regulated by the plumbing code, not the connection of the piping to the mechanical equipment. The rub may come if the standpipe diameter is too small to admit both the washer drain and the clip holding the condensate drain at the same time. A neutralizer is easy to make with a length of 1 1/4 pvc pipe and some marble or lime chips. While most manufacturers don't specify this on gravity ductless drains, it is something to look out for. From what I can tell, both local code (IPC 2018) and the water heater install guide only say that the condensate line needs an air gap. Condensate waste shall connect indirectly to the drainage system through an air gap or air break to properly trapped and vented receptors . damage to any building component could occur as a result of overflow from the equipment drain pan or stoppage of the condensate drain piping: For Indoor Use: Stay in the . @John W., See attached pic for mock-up. mechanical service equipment; electrical components; automotive; domestic refrigeration; .
