Frequently Asked Questions About Hydro Jetting
What is Hydro Jetting?
Hydro Jetting (a.k.a 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 3,500 psi. These high-pressure streams are strong enough to cut through and clear out any debris in your sewer lines.
How does Hydro Jetting work?
Hydro Jetting is typically done through an opening called a cleanout, which is an accessible opening present in every plumbing system and designed to allow plumbers to easily “clean out” debris and other clogs. A Hydro Jetter consists of a large tank of water, a special high-pressure hose, a special high-strength nozzle, and a machine which pressurizes the water in the hose so that it can spray out of the nozzle at a pressurized rate of up to 3,500 psi and a flow rate of 18 gpm.
Every plumbing system is designed to carry wastewater “downstream” using gravity. The Hydro Jetting nozzle is placed at the “downstream” end of the plumbing system and it works its way “upstream” against gravity. That way, any debris that is cleared out by the Hydro Jetter will harmlessly flow downstream where the drainage path is already clear. The Hydro Jetters used by general drainworks are capable of clearing out sewer lines over a length of several hundred feet.
When would I need Hydro Jetting?
Hydro Jetting is an appropriate solution when clogs cannot be removed through traditional snaking, such as in the presence of stubborn roots that have found their way into your sewer lines. Hydro Jetting is also required before Pipe Lining because any debris present in the existing pipe may cause the epoxy lining resin to be malformed and / or prevent it from bonding correctly to the existing pipe.
What are the benefits of Hydro Jetting?
Hydro Jetting 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 Hydro Jetting 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, General Drainworks recommends getting a Camera Inspection to determine the seriousness of the condition, because sewer line replacement via Pipe Bursting may be required.
