condensate dain

tell your install manager to look at the wall. There is no reason to think condensate would not freeze even if in a 4" pipe. if it is below freezing outside, is condensate some magical water that won't freeze? We never, ever pump heater condensate or humidifier waste water outdoor. We pump to sump pump hole. There should not be enough water generated to ever even turn on sump pump.

condensate drain 90% furnace

Need help finding information (in print if possible)to show installation dept that the condensate which is pumped from the condensate pump will freeze if pumped outside.Some believe that if put into 1" pvc it will not freeze.I have found frozen condensate lines every time weather gets extreme cold and find it non productive to run around thawing pipes incorrectly installed.Need help finding reference material to print and quietly send to installation dept.Thanks in advance for any and all input!

1.) Condensate is principally water

2) Water freezes at 32 degrees F.

3) Confirmation of this can be found in any grade school textbook.

4) It does not matter what pipe material contains it. Some are more conductive than others, but all will eventually allow freezing.

Condensate freeze

Page 15 Armstrong Air G2D95BT gas furnace I&O instructions

"The condensate drain line should not be run directly to the outdoors especially in colder climates where temperatures may cause the condensate to freeze in the drain line."

Page 20 Weil McLain Ultra series 2 I&O manual

"If condensate is allowed to freeze in the line or if the line is obstructed in any other manner, condensate can exit from the boiler tee, resulting in potential water damage to property."


You don't have to look too far to find it in print.

Call me crazy..........

but we have 6 Ultras installed so far in North Jersey and for condensate on each one of them, we drilled a 1/2" hole angling up toward the basement and then snaked a 1/2" polyethylene tube through the opening which is angled down and have never had one freeze up as the tube empties completely each time.

Adam...\"you crazy, man\"

I assume it was pumped, yes? Code requires us to pipe all condensate to an open site drain. If none is available, we pump to one. We're not required to treat it...yet, though I have.
