have never had problems dumping furnace or humidifier in sewer. a/c units it depends on town. one thing you don't want to do is dump furnace into a copper drain line. i am in burlington county.
hey guys i,m new here {great web site}.just wondering;is it ok to dump the condensation water from 90+ gas furnace into the sewer drain or should it be pumped out doors?i know some state have diffrent laws ,i'm in south jersey{don't hold that against me}is there an industry standard?.thanks guys!

The only real concern with dumping condensate water from a condensing furnace is 'will the low Ph water solution harm the piping it flows into?' The Ph is on the acidic side and can harm copper quickly and eventually, cast iron. I feel we will see problems in years to come with some damaged underfloor drain piping materials. So long as the condensate is diluted with other waste water, the problems are minimized. If your drain piping is plastic, like PVC or ABS, you should have no worries at all with this issue. I would be hesitant to dump it outside. First of all, as the water will freeze and the acidic levels could stain brick, concrete walkway, patio or whatever surface it drains onto. On the other hand, your Azaleas might love it, as I hear they like slightly acidic soil conditions!
Don't confuse me with facts, my mind is already made up.
if you pump it outside it will freeze and flood basement or turn off heat.Sewer is best,septic system second,outside the last choice.

I disagree. I have had several customers whose condensate lines were attatched to the sewer line. Eventually every one of them required a service call because the sewer line stopped up, pressurized, and pushed sewage, rotten food, and cooking byproducts through the trap and into the air handler/furnace.
Aside from filling your house with a disgusting smell, the potential exists for fire (cooking oil/grease coating the heat exchanger). In the 5 states I have worked, it's against code for the condensate line to be run into the sewer. A properly sloped condensate line @ the end of a condensate pump will prevent freezing. Or run it into the sump if the unit is in a basement.

would take a total moron to tie a condensate line from a furnace or air handler directly into sewer line. most of the time when we go into sewer we are going in alongside of washing machine with discharge from condensate pump. no way this could harm unit.
if they allow it or not there are a couple factors.
One, supposed to be an indirect connection so an air gap, a trap with TSP.
Some places get as extreme as requiring a ph kit on it to neutralize the acid
