Re: a/c condensate terminating at sink drain
Jerome,
The drainline in question is probably the primary condensate. It should not be vented to a sink. Although typical to see, it is wrong.

Re: a/c condensate terminating at sink drain
You should probably mention the broken dishwasher drain line, unless I am seeing that wrong.
OK, I think there is an elbow there, its hard to see.
The AHJ here allows condensate drain connection to a drain if there is a check valve, I don't know if thats OK other places.

Re: a/c condensate terminating at sink drain
Fritz,
I learn years ago not to attempt to determine or what is acceptable by every AHJ in our area. He77, you'll get 2 different opinions from the inspectors within the same city.

Re: a/c condensate terminating at sink drain
It's been my experience that there should be a 4" air gap between the sewer drain and the condensate drain. That prevents bacteria from working it's way up the line and into the air handler. When I see these I call them (if I'm sure it's the condensate drain).
I've had sellers, agents and even some old time HVAC techs (that's the way we have always done it) go off on me about it but that's the price of fame.

Re: a/c condensate terminating at sink drain
Bruce, when you say "4 inch air gap", are you talking about (in this picture) 4" from the sink's p-trap to where the point where the condensate line connects to the sink's drain?

Re: a/c condensate terminating at sink drain
UPC says it's okey dokey.... (C)
Since the Uniform Plumbing Code says it's ok, the folks at Code Check recoginize it as o.k. as well.
Good'nuff for me.

Re: a/c condensate terminating at sink drain
- Is that lamp cord plugged into a regular outlet running to feed the disposal unit?
- If that's the DW drain hose running to the disposal just sort of laying there then it doesn't look like it has the trap loop going for it.
- Might consider mentioning that they may get some smell out of the kitchen sink with the condensate hook-up like that. Especially if there's no trap on the pvc coming through wall or if the unit doesn't run for a while.
Just wondering.

Re: a/c condensate terminating at sink drain

Re: a/c condensate terminating at sink drain
I'm not a code guy, I don't even use the "C" word. The code is only a place to start in my mind.
When I said 4" air gap I was talking about a drop in open air from the condensate drain into the sewer drain. That way bacteria from the sewer can't find it's way into the air handler from the sewer.
I think it's a good idea but then again there is that "C" thing. The politically motivated good place to start.

Richard,
"Good'nuff for me."
Ummm ... are you under the UPC? Or the ICC codes?
And ... do you have the wording in the UPC which allows it?

Re: a/c condensate terminating at sink drain
In my world, it is against the law to dump a condensate drain or any sump pump drain into the municipal sewer system. A utility co. manager explained to me that sewer systems are almost always operating at capacity and they'd just as soon not treat water just for the sport of it.
The city has apprised builders of it and demanded that they cease.\

Re: a/c condensate terminating at sink drain
Jeffrey, where is your part of the world?
Around here, NOT putting condensate in the sewer would be asking for trouble with foundations.

Re: a/c condensate terminating at sink drain
jim:
I'm in Greenville, N.C.
I accidently ratted out the practice.
I inspected a crawl space with a sump pump and casually called one of my better friends who manages a division of Greenville Utilities. He asked up the line and I had an idea that it was against the policy of the utility co to dump anything into the sewer other than house waste. He confirmed that as well as that condensate was also improper and, in fact, statutorily illegal.
Why would any condenste pose a foundation issue if it is properly lead away from the house by proper grading?
Around here, we're just a smidge above sea level as it is, but decent grading will disburse that amount of water satisfactorily.

Re: a/c condensate terminating at sink drain

Expansive clay soils. During the 6 or 7 months of not stop A/C use with no rain for months sets the stage then add in a 5' side yard dumping condensate on one side of the house and your in trouble. They used to put in a dry well of sorts a foot or so away from the foundation and dump the condensate there, but that is a rarity now.

Re: a/c condensate terminating at sink drain
I would have to agree with Jim you do not want to dump the condensate to the exterior but to the dwv. So why not the sink drian as long as it is before and above the trap???

Re: a/c condensate terminating at sink drain
Don't know what different types of bacteria are in the two, but I suspect they are not the same.
Seems as though that must make a big difference, 'cause the code (being "minimum") recognizes it, and if "minimum" recognizes it, why would one want to challenge it and go against even "minimum"?
Beats the heck out of me why some so insist, though.

Ok, I must be behind I'm unaware of any code dissallowing this type of termination point???
