So I was walking around the back of the house and heard this gurgling coming from where the outside air line exits the house. Sure enough, hot moist air when it entered the cool basement had accumulated water to the point that it was partially blocking the air intake to the skimmer. I'll punch a hole in the poly tubing at a low point but just thought I'd share as I'm sure others have probably experienced or not realized this was an issue. I have 3/4" poly tubing from my lawn irrigation system, so I can only imagine if a smaller diameter tubing was run. This is the first summer with the air line running outside, so I'll have to check it frequently. But it's definitely worth it, as my pH stays between 8.2 and 8.4 (kalk doesn't hurt either). Growth has been fabulous since keeping the pH high.
