Sewer Jetting: Key Facts You Need to Know
What’s a Sewer Jetter?
Sewer jetters, also known as “hydro-jetters” or “water jetters”, are powerful drain cleaning machines that use high-pressure water jets to clear obstructions in residential and commercial drain pipes as well as larger municipal sewer systems.
The simplicity of use, safety, and efficiency of cleaning are the main reasons many plumbers and drain cleaning professionals are turning to hydro-jetting as the tool of choice.
Sewer jetters can be truck mounted and may carry up to 1,500 gallons of water for large sewer cleaning jobs, or they can be mounted on a trailer and pulled by a large van or small truck. Smaller water jetters can be mounted on a cart for light residential and commercial applications.
How Does a Jetter Work?
A high-pressure sewer jetter consists of a pump, a motor or engine, a hose reel, a given length of hose and a various assortment of nozzles. Portable water sources may include one or more water tanks. For example, the Spartan High-Flow Ultimate Warrior hydro-jetter, shown below, employs four baffled water tanks that keep the jetter balanced when tanks are full and the jetter is being towed to a job site.
The jetter’s high-pressure pump is key to delivering powerful jets of water needed to clean drain and sewer pipes. The high-pressure hose is wound on a powered reel that enables the operator to retract the hose easily — 500′ of hose weighs several hundred pounds.
A pipe is cleaned with a high-pressure water jet by directing water pressure and flow through a nozzle. Controlled water pressure and flow propel a water jet through the sewer pipe allowing it to remove and wash away the obstruction. High-pressure water jetters usually operate with water pressures up to 4,000 PSI with flow rates of 2 — 25 gallons of water per minute. Some municipal hydro-jetters have flows up to 120 gallons per minute. The bigger the pipes, the larger and longer the water jet hose is needed to clean them properly.
Ideally, a sewer pipe is cleaned from the lower end of the pipe and the hose propels itself to the higher end of the pipe. By slowly withdrawing the jet hose, the water pressure and flow clean the line most effectively. When it is impossible to clean from the lower end of the pipe, the pipe must be water jetted several times to remove all the debris. A skilled operator can effectively clean a drain/sewer regardless of the obstacles in their way.
