Unlike a clog caused by grease or a foreign object, scale is a hard, rocky substance that bonds to the interior walls of your pipes. In Abingdon and the wider Oxfordshire area, this is particularly common due to two factors: descaling sewer line abingdon
Before any work begins, an engineer will insert a camera into the line. This is crucial. They need to confirm the blockage is scale and not a collapsed pipe or root intrusion. | Method | How it works | Best
: A specialized descaling machine—such as the Ridgid FlexShaft —is inserted into the drain. This machine uses an electric drill to spin a shaft with expanding chains that scrape solid scale from the pipe's circumference. They need to confirm the blockage is scale
In the past, fixing scaled pipes meant digging up your garden (excavation). Today, Abingdon drainage specialists use . The standard procedure for descaling is as follows:
