4 year old home, Calgary, Alberta Canada. Water/condensation draining back through soft 4" corrugated flexible vent hose onto ceiling and vent. Viewed in attic and found long (10 ft and then vertical for another 10 ft) length of same soft corrugated hose/insulated vent pipe with "custom" goose neck.
The hose was bent into a goose neck.

Did recently install new drip humidifier but turned it down to under 30. Adjusted again to under 20.
Calgary climate very dry, because of this problem do I now have to turn the new humidifier down to where its usefulness and efficiency is compromised?

Should this have been a hard pipe plumbing application?

Thanking you in advance.

Wrap the vent hose with pipe insulation. Insulation should prevent the moist air inside the hose from condensing and dripping down.

20' is a lot of duct. I have no idea if that in itself could be part of the problem, but it is advised to wrap the duct with insulation.
