Switched from a wire brush to poly brushes on clay tile liners and the difference was night and day
I was using a standard 8 inch wire brush for years and kept getting callbacks on clay tile jobs, mostly small chips and cracks near the top. Picked up a poly brush set back in March for a job in a 1920s house and the rods ran smoother with way less drag. The wire was just too aggressive on older tile, and I was probably cracking some without knowing. Has anyone else made this switch, and do you still keep wire in the van for certain flues?
