Product review (5 stars): Great Item!
This is something I wasn't sure if it was going to work or not!  We have a long tube that goes through the roof and out the side of the house, so when it got clogged, I wasn't sure what to do. I called someone to come clean it, but after a month or two, it was clogged again!  So I decided on this.  I have now had it over a month and it has been great! So much easier to work with, and all i have to do is change the water in it ever now and again!
