This is Chris O. He is a lead technician on the A-1 team performing cleaning and Descaling of 43 roof vents before we install 176-foot of 4” CIPP Pipe provided by Perma-Liner Industries. My team and I find it imperative to clean and prep all laterals before installing and CIPP down the mainline. This helps stop resin balls that form and mix with build-up and debris that is in the laterals.
Example.. average reinstatement without proposing laterals is 45min due to the gunk build-up.
The average cleaning takes up to 30 minutes and provides a better product for the customer. The average reinstatement for a clean lateral is 12 minutes. This also makes a manual reinstatement quicker. When the bubble does not form, you are able to get a camera down the lateral to illuminate the reinstatement area without having a line full of debris and pulling the camera out several times to clean the head. In the following pictures you will see CIPP, one is a project we performed for a contractor who refuses to clean laterals and the reinstatement’s take a very long time, they look bad and cause stoppages. The other pictures are a reinstatement with a properly cleaned lateral. No debris falling out of the pipe.
