High Pressure Hydro Jetting

High Pressure Hydro Jetting

High pressure hydro jet cleaning (Hydro Scrubbing) is a process in which your sewer pipes are scoured by streams of high-pressure water shooting out of a hose at up to (241 bar) 3,500 psi. These high-pressure streams are strong enough to cut through and clear out any debris in your sewer lines.

There are a lot of good ways to prevent a blockage and clean out our restaurants pipes, but the best out there may be Hydro-Jetting. If you’re considering Hydro-Jetting, here are 5 helpful facts you need to know.

  1. Hydro-jet cleaning works by shooting high-pressure water streams to remove build-up in pipes. Water blasters use extreme pressure from 7,000 PSI to 60,000 PSI. Pressure and Flow are the two main factors in how hydro jetting works. For softer materials, higher flows work better. For hardened materials, a higher pressure will better loosen it. Each problem is unique, though, and your vendor will decide the best way to attack your problem.
  2. High pressure jetting was invented 1950’s. It used to be an expensive process requiring large equipment, but it has progressed, like computers, into an efficient unit that can be operated by a single plumber.
  3. The pump, engine, hose, and nozzle make up the main components of a hydro-jet. The pump and engine create pressure shooting water through the hose, to small orifices in the nozzle that restricts the water flow. It’s the speed of the water and the volume that loosens buildup and debris. Forward facing jets clears the debris. Rear facing jets flush everything out and propel the hose up the pipe. Rotating nozzles remove grease and roots.
  4. Hydro-Jets can be used for the lateral pipes and drains. Both are the responsibility of the property owner. Lateral pipes are pipes that connect a building’s drainage system to municipal sewers. Blockages in these pipes can cause expensive pipe collapses. Drains are located under or within the building, and contain “elbows” for wastewater directional changes. Both kinds of pipes can suffer from food grease buildup, soap residue buildup, dirt and debris accumulation.
  5. Hydro-Jetting contains, captures, filters, and reuses water. This stops harmful wastewater and dangerous contaminants from re-entering the environment. This environmentally-friendly feature is not available with other cleaning abrasives like silica sand.



High pressure hydro jet cleaning can easily cut through the most stubborn roots and debris and remove built-up mineral deposits and other obstructions clogging the inside of your drainage line.

Although high pressure hydro jet cleaning is strong enough to clear out roots from your sewer lines, any amount of root penetration is cause for serious concern. Root penetration pervasive enough to cause repeated backups indicates that the roots have gotten thick enough over time to damage the pipe and its protective waterproof inner coating. In those instances, Pressure Jet recommends getting a Camera Inspection to determine the seriousness of the condition, because sewer line replacement via Pipe Bursting may be required.

High pressure hydro jet cleaning is a method of cleaning equipment holding tanks in recreational vehicles. This method uses high pressure streams of water to remove virtually all build up in tanks and lines.

Unlike chemicals and enzymes which remove very little build up and can be detrimental to the environment, hydro-jet cleaning equipment completely cleans all holding tanks with no ill effects to the vehicle or the environment.

This process may best be compared to "power washing" which has also gained popularity as a means to clean driveways, homes, streets, commercial vehicles and more.
