Hydro jetting just means that you are cleaning your drains with extreme water pressure. Hydro jetting is different from snaking or other types of drain cleaning because it requires heavier equipment and has to be done professionally. Hydro jetting is usually needed for commercial properties like restaurants or hospitals, but it can work for residences as well.
The kind of water pressure that can clean your clogged drains usually has a pressure that is between 1500 to 4000 pounds per minute. This kind of water pressure will usually clear out the kind of grease, sand, and sediment that has built up in your drains. This is the kind of buildup that causes your sinks and dishwasher to back up. No one likes filthy water to come back up on them in the place where they wash their hands or their dishes. This is why it is important to get a hydro jetting job done by your local plumber if you suspect that you have clogged pipes caused by something like grease.
The jetting tool works in two ways: First, the jetting tool has a high water pressure stream that cleans your pipes while it moves forward. Second, the way the jetting tool moves down the pipes is because it is propelled forward by reverse water jets. These reverse water jets work along with the forward water jet to break up all of the obstructions in your drain pipes. This is because there are about 6 to 8 reverse water jets that work to break up the blockage in you drain. The reverse water jets are really what work to break up the blockage in your drain when the forward nozzle is pulled back against the rear water jets to create a force that will clean any drain without having to perform major construction on your pipes.
Your local plumber may also have some other solutions that you may not have considered. This is why it's better to call them and get some useful information, and also a free estimate before you do any major construction work on your property that involves working on the drains.
