Was in HD again the other day browsing around the seasonal aisle. I spotted a Rutland round 6" Poly brush and brought it home. Something like $15. I was surprised at how hard and rigid the brush is. Anyhow, I wanted to do a test run on some extra length of my 6" liner before I attempt a sweep in a month. The brush definitely fits snug and makes a scraping sound while pushed and an even louder scraping sound when being pulled. Is this typical? After pulling it out I checked the liner to see if it scraped it. It didn't. Also, I tried twisting the brush a little while inserted. Didn't seem it wanted to do that. I'm going to guess that poly brushes aren't supposed to function like a soot-eater, yes?

The brushes I uses for sweeping liners is alot softer than that. I would be hesitant to send that one down a customers liner, especially if I wasn't the person that installed it. I would try to find a soft bristle poly brush for your liner.
 
This is the one I use on my flex liner and I have not had a problem. Doesn't kink, scratch or mess the liner in any way. It definetly is stiff but it gets the job done! If it is were me I would not twist it while it were inserted. If you twist it off, you may have burn it out of the pipe, if that's possible. I actuall wrench my rods and brush together.

Really? Why?
 
Lol, gotcha 5' of Insulflex left over do ya? I have some too... don't know what I'm gonna do with it! That's a good pic of the liner, the other ones folks have posted on here have foil wrapped at the end so it's hard to see the insulation in the picture.
I bet after you sweep with that once or twice it's gonna bend up a little at the ends and won't make so much noise. I don't know that though, I haven't swept my own yet and just bought the sooteater too.
 
That brush will do the job just fine. And no, you shouldn't try to twist it like a Sooteater.
