Because the vent in the drain line is open.
Auxiliary condensate line dripping outside. I live in a two story house which has two units; I checked the drip pans in the attic and they both are dry. I pour a bleach solution into both primary condensate lines but the dripping outside continues; now I'm wondering if the contractor/AC people hooked up these lines correctly. I'm no AC man just learning.
Can anyone tell me why this line is dripping outside?
See attached photo of evaporator with condensate lines.
TIA
Because the vent in the drain line is open.
the trap is most likely plugged
try to blow it out
The house is only 3 years old and there has never been a cap on that vent or my other vent coming from the second unit.
1. I poured a bleach solution into the vent earlier today to clean the p-trap.
2. Should I put a cap on the vent?
Thanks so much for your help and quick responses.
since this is a positive pressure coil witch mean it is on the supply side i recomend leaving the cap off. You will get conflisting optinions on this because it is on the supply
if on the return or negative pressure ciol the yes the cap has to be on or it will not drain
bleach with not clear the trap once it is plugged. It will help clean it wonce it is clear
I agree its not much air that blows out of it. But it is an air leak, and should be sealed/capped off.
After all, wouldn't you seal a leak in the duct if it was that big.
No harm from capping it.
You won't blow cool or heated air into teh attic if you cap it.
now that you put bleach in the pipe i would stromgly reccomend you dont blow through it or you may get a mouth full of bleach. That would not be good.
best to leave it and see if the bleach works
call for service could be clogged inside coil and also if the have not been serviced this year they should be
One other thing.
Is that an N coil?
Post the model number.
Thats an N coil.
And if its installed that the right hand side has to have a block off plate, it tends to freeze.
