Jetters are used to thoroughly clean a line. With their high pressure power wash they can descale and clear off roots in a main sewerline or blow out built up grease in grease traps. The smaller sized jetter also known as a "Mini Jetter" is used to power wash grease and build up out of drain lines such as kitchen sink lines and floor drains. Although cable machines are usually used to clear clogs and cut through hard debris, jetters are used to efficiently clean and push out debris and grease from a line.
