With modern advancements constantly being improved upon, jobs that used to take days can now be completed in one day. From the large machines contractors use to clear land, to the equipment used to clean homes and workplaces; everything works better and faster than it once did. These new and better methods can also be very dangerous if proper precautions are not taken when people are working with them. Workers have to be taught how to handle the equipment so they are not hurt in the process of doing their jobs. Many machines have so much power, the person working with them must be very careful, or they could lose their life.
This is how it is with sewer cleaning equipment. Most people don't consider how dangerous it is when employees work with highly advanced or extremely heavy machinery. Many times the earth has fallen in around workers who would have suffocated if not for fellow workers digging them out so quickly. To keep up with a fast paced world, plumbers invest in drain cleaning equipment, such as sewer jetters. These jetters are available in various sizes depending on the job a plumber has to do. They often rent the machines if they aren't needed all the time. Other plumbers who want to build a reputation for doing very large jobs, buy their own sewer cleaning equipment instead of renting it.
The sewer jetter is also called a hydro-jetter or water-jetter, and is extremely dangerous because the pressure of the water coming through the hose is very great. If this pressurized water hits the skin, eyes or face, it can go right through the body causing death to a worker. Anyone who has been watering the lawn and the hose fell out of their hands has seen how the hose practically danced across the lawn. Picture the force of a hose and nozzle with water coming through it at a pressure of 2,000 or 4,000 pounds per square inch (PSI).
While this kind of pressure easily clears pipes of debris, protection must be taken when turning the power on and off. If the hose is pulled out of the pipe too quickly after turning the water off, there is still pressure in the line. Workers must be trained to keep clear of the hose nozzle that can hit the body and break the bones in their legs and arms, or fracture their skull. Today, plumbers make life much easier for business and manhole hooks homeowners, even though some situations are extremely dangerous. They work outside on freezing days, unclogging drains with special drain cleaning equipment, and in emergencies when customers call them to repair leaks in the home.
To make the plumber's job easier, plumbing supply companies sell the hydro-jetters and other tools plumbing companies need to do their jobs much more safely and efficiently.
