IIRC it's the text shmiras shabbos kehilchasa that allows you to use an ordinary plunger -- but not a professional-grade one -- to plunge a clogged toilet even on shabbos. So you'd certainly be allowed to do so on Chol HaMoed. As for using a professional-grade plunger ... I don't have a source.
I phoned a rabbi — probably one of the top ten rabbis in my city (a North American city of three million people). He's a charedi Ashkenazi rabbi. He said I can unblock it using a plunger, since it's unskillful work.
