Just crawled under the cottage to change the furnace filter and I noticed that the drain tube seemed to be kinked. Is there a functional reason for the drain tube to be curled like that... other than to prevent the tube from hitting the sand??? I retaped the tube to give it more slack in the curled portion to hopefully prevent any further kinking.
Also noticed a large amount of ice below the exhaust pipe outside. Is this due to the furnace not draining properly?
I'm obviously a novice. Any help would be appreciated.
