Anyone with experience in typical plumbing codes have advice on this? I need to route the condensate drain on a high efficiency furnace/AC to an appropriate drain.
It appears that going outside is not a good idea, because it's subject to freezing here and also I'm not keen on putting extra water near the foundation in the most logical area. I don't have sump pump, so can't drain it to a sump basin.
Here it's permitted and apparently a preferred method to route it into the sewer system. The simplest way would be to route it to a laundry sink drain. Problem is I don't have one in the basement and the first floor one is on the other side of the basement and running anything up there to it isn't going to be easy either.
So, what I came up with is this. I have a shower on the first floor that is within range. The trap is accessible with maybe 7 inches of DWV pipe between it and the shower drain. I am looking to connect into there, above the trap. I've seen online where HVAC guys have tapped into all kinds of sewer or sewer vent lines using some kind of barbed fitting where they just drill a hole and screw it in. But I know some or all of them don;t meet code. But I'm wondering if you do it in the right place, ie it's protected by a trap, is that kind of connection code compliant? And what kind of fitting would one use? I don't recall seeing any barbed fitting other than standard pipe threads. Would think you'd need some different thread to screw into a hole drilled into DWV pipe.
Or alternatively, let's say I cut the drain pipe, install a wye fitting, reduce it down to a barbed fitting and then connect the hose to that, is that code compliant? I would think it would be, but not sure.
Any thoughts?
