There are many jobs out there that can be performed using pumper and vacuum trucks - and there is much demand for these type of services. One idea for a business to consider when looking at expanding their services is jetting. High pressure jetting can be a profitable venture for a company purchasing new or used vacuum trucks for sale. In order to provide the best service possible, and to get repeat business, it is important to understand what the best practices are for effective jetting.
Inspect the Site and Be Prepared
Effective jetting requires use of the proper hoses and nozzles based on the work being done, and the type of debris being removed. Jetting with the wrong equipment slows work down. When customers are paying for that time, this can become a problem. Viewing a drain line by sending a camera down first is a good way to get a preliminary idea of how things look, and how to begin clearing the line. With that knowledge, choosing the right equipment, and deciding how a clog needs to be cleared, is much easier.
Use the Right Equipment
Getting a jetting job done efficiently means using the right equipment, just like any other service performed using new or used vacuum trucks for sale. Following are some pieces of equipment to consider when doing this job:
- Nozzles - It is usually better to start with smaller, higher penetrating nozzles to break up debris. It can then be cleared it out with a larger nozzle afterwards. This is especially true if it is not possible to send a camera down the drain line to see exactly what is in there. A larger nozzle runs a higher risk of getting stuck, while the finer nozzle can do a much better job in all cases of loosening things up and clearing them out.
- Hoses - In most cases it is fine to start out using the standard hose for the nozzle, but keep in mind that pressure (the right pressure, at the right time) is everything. Also, the longer the hose being used, the greater the loss of pressure at the nozzle. This is because hoses tend to lose one to two pounds of pressure for every foot of hose. In cases where a longer hose is required, switching to a smaller diameter hose can help keep pressure high.
Use the Right Techniques
There is more to the jetting procedures done by vacuum trucks than simply sending a hose into a drain line and turning it on full blast. Considering the power water under high pressure has, it is essential to operate jetters carefully, and use the right techniques. More can be accomplished by starting off slowly to resolve clogs with lower pressure, than trying to simply cut through them in one go at higher pressure. This is especially significant when clearing out things like tree roots, rocks, and other stubborn blockages.
Working upstream of clogs and debris helps the effort, as water flowing downstream can help clear things out, as blockages are being jetted. When clearing drains, taking time to do a thorough job without rushing things can accomplish much more. The clock may be ticking, but taking things more slowly at the beginning can help get the entire job done more quickly.
Along with providing the right training, and teaching of important safety procedures, any company using vacuum trucks in this capacity can do quite well as long as they follow the right basics. When considering the purchase of additional new or used vacuum trucks for sale, jetting services can be just the addition a company needs to increase revenue, and keep those trucks out there working!
