High pressure jetting has been around since the early 1950's. What once was an expensive and massive jetting machine that required huge quantities of water has evolved into a highly efficient and manageable jetting unit affordable for the average plumber.
High pressure water jets are great investments for contractors, municipalities, or anyone in the drain cleaning industry. High pressure units are useful in any industries with reoccurring blockage issues or where byproducts regularly create drainage problems. Water jets are most commonly used for sewer drains and storm lines, but they are also used in process pipes, chimneys, and stacks that accumulate debris over time. Additionally, they are great machines for pressure washing and heavy duty wash downs, such as in quarries, airports, and stadiums.
What is high pressure jetting?
High pressure jetting is using streams of high pressure water to clean, cut, and remove debris. The main components of a high pressure jet are the pump, engine, hose, and nozzle. The pump and engine work together to create high pressure water through the hose to the nozzle. The nozzle has small precision machined orifices that restrict the water flow, thus creating high pressure build up in the hose. Water shoots out of these orifices, and converts from pressure to velocity, and it is the speed of the water combined with the volume that does the work. The angle of the jets in the nozzle create the forward propulsion to take the nozzle up the pipe. Forward facing jets will clear and cut through debris, while rear facing jets flush debris back and propel the nozzle through the pipe. Rotating nozzles create a 360 degree cleaning action which is ideal for grease and root removal.
When should a high pressure jet be used?
High pressure jetting is an extremely efficient way to clear a blocked pipe or drain. Jetting can be done in any sized pipes as long the appropriate pressure and flow is used. Sewage, grease, scale, roots, etc. are all debris that can be blasted away with a high pressure jet.
When it comes to drain cleaning, preventative maintenance is very important. Waiting until a drain is completely blocked is an expensive inconvenience that can shut down businesses, roads, buildings etc. Routine maintenance with a high pressure jet will help to avoid these issues before they happen.
Where are some places high pressure units can be utilized?
- Sanitary or Mainline Sewers: located under streets and roads that connect building laterals to a municipal wastewater plants for treatment. Sewer blockages can form as a result of root infiltration, food grease buildup, soap residue buildup, dirt and debris accumulation. Blockages can also occur from pipe failure or collapse that may require excavation to correct.
- Laterals - Pipes that connect building drainage systems to municipal sewers, considered to be part of the property and the responsibility of the property owner. Typically, laterals are 4" & 6" diameter pipes that connect directly to municipal sewer pipelines, but can be larger for commercial or industrial buildings. Lateral blockages can form as a result of root infiltration, food grease buildup, soap residue buildup, dirt and debris accumulation. Blockages can also occur from pipe failure or collapse that may require excavation to correct.
- Drains - Drainage pipes are located under or within buildings, considered to be part of the property and the responsibility of the property owner. Drains in buildings can range in sizes from 2" to 6" diameters (typically) that normally contain "Tees" or "Elbows" for wastewater directional changes. Drain blockages can form as a result of food grease buildup, soap residue buildup, dirt and debris accumulation.
- Storm Drains - pipes that are limited to the collections and control of rainwater. Storm drain blockages can form as a result of root infiltration, silt, dirt and debris accumulation. Blockages can also occur from pipe failure or collapse that will require excavation to correct.
- Process Pipe & Conduits - Pipes of all diameters & lengths used in manufacturing plants, chemical plants & food processing facilities that transports liquids other that sanitary wastewater or rainwater. Blockages in process pipelines can be caused by many factors related to the process. Each individual application occurrence will have unique factors to be dealt with on a case by case basis.
- Quarries, Airports, Stadiums - anywhere where pressure washing can be utilized to wash down machines, clean oil and debris off runways, or remove graffiti, stains, and gum off concrete.
