 Condensate pump drain for furnace
Author: Jean9fixit (NY)

Hello everyone! First time poster here. I have a previously owned furnace that is a stand-in for a very old furnace that has no more winters left in it. It is only to tide us over til spring/summer when we will get a new one. The 2nd hand one isn't as big as the old one.


My question is, when I get the condensate pump (c. pump) how do I drain it? Dirt floor cellar, no floor drain, no laundry sink. Any thoughts, ideas? My ideas, in no particular order are, let the water, without the pump, drip into a bucket I will empty everyday. Did it 2x a day from the dehumidifier down there.

Next, do i sink a 5 gal. bucket into the dirt as a sump hole, and drop a sump pump in it, to direct the water from the c. pump into and hook the sump up to the main drain pipes? And lastly, attach a plastic tube to the c. pump and run it upstairs to a nearby toilet and hook it over the toilet tank edge. When it flows, it will just go down the overflow tube. These are just brainstorming ideas.


Another question. Do c. pumps come in different sizes for the different sizes of furnaces? If so, I want to get a larger one in anticipation of the larger furnace. When I say larger, I mean as in more BTUs, not sizewise.

Silly me, I forgot. Forced air, natural gas furnace. Thanks for any help anyone can give me.

you have to realize that if the condensate you are talking about is the condensate from flue gasses then it must be neutralized before disposing of it.

it is far different from the water that drips off air conditioning coils.

as far as where to send it...

ideally you could stich the 1/4 inch plastic discharge tube into the washing machine stand pipe.

example of a pump with neutralizer...

Oh, I didn't think of the washer stand pipe. So it being pumped up to the washer stand pipe on the 1st floor, but less than 15-20 feet across/up to there is acceptable?
Do the condensate pumps have the neutralizer built in or is it separate?

yes it will pump up that far easily
not all condensate pumps have neutralizer built. some pump air conditioner condensate which doesn't need to be treated.
