I live in a manufactured house. I was under there for something else and touched the big black pipe(guess it sends the air to the vents). The one had a bend in it and had a small amount of water on the plastic on the ground. Moved the pipe and could tell had water. So i put a small hole in it to drain. Went to the other pipe and touched it and could tell it had water. The pipe goes up to the unit in the house and it was wet at the very top. I have noticed the drain pipe is not get a lot of water out as last yr when have been out there. Why is there water in the hoses and is that bad? I cleaned the drain pipe (tried to with a hair remover thing that is 24 in long)in the drain at the unit in the house. What can i do? thanks
