I know this has been a topic in the past but I think you guys can answer my question.
I am getting a whistling from the air hole in the main drain because, from what I can tell in videos, that entire curved main pipe should be fully submerged.
How do I fix this? Cut a shorter pipe and replace, adjust gate valve on drain?
Thank you in advance.
