When the temperature is below freezing.  I'm  assuming it's a two part 
First, water must be getting in  somehow.
Second, the water freezes when its cold.

    Since the PP's weren't meant to be  installed vertically, the water is 
a problem. OT's who used them used RTV  to seal up all of the top holes - 
and there are several of them. Sorry I don't  know all the details. One thing 
you can do is to build a little shroud or  doghouse that goes around the PP 
and keeps the wx out.

    Well, you're going to need it. That's what you're  going to have to do 
- one of those pipe heating tapes will do a great  job. That's the same 
thing I had to do with mine. Annoying once but  wonderful when it's cold out
