The Clog Hog is well built and robust. After watching the videos and then placing the device in service, I was able to clear three lines in under 20 minutes. I marked the Clog Hog with duct tape at 25%, 50%, and 75% lengths. The device I bought was 50ft. I knew that my clogs were from 0-12.5 feet as total occlusions based on the marks and my line inspection. Your device saved me $3800.00 dollars because I was told that I needed a new drain field. Septic owners should know they have alternatives. I will use this device annually as a preventive maintenance program. Thank you so much!
