Professional plumbers use different methods to unclog blocked drains. They may vary from plumbing snake/auger, rodding, and hydro-jetting. While snaking and rodding are traditional ways of cleaning your drain, these methods have a limited effect and do not scour your pipe walls completely.
Complete and thorough drain cleaning is only possible with hydro-jetting that involves the release of hot water jet stream at very high pressure to remove the most stubborn of blockages to restore normalcy.
You can also hire bonded sewer contracting services in Los Angeles as per your needs.
Plumbing Snake/Auger: The plumbing snake/auger is made of a metal tube. It has a cable inside with attached metal blades. It is hand-cranked as it is lowered down the drain so that the blades can punch holes through the blockage.
You will feel some resistance when the plumbing snake comes in contact with the clog. Keep turning the crank until the snake is all the way through the clog and then you can pull it back.
Hydro-jetting: Plumbers used to rely on traditional drain cleaning methods until technology made things easier for them. Hydro-jetting is the industry's new and the most powerful standard in scouring drain and sewer walls completely of fatty and greasy build-ups that cause drain blockage in the first place.
In this process, a hot water stream is released through a nozzle at very high pressure, approximately 7000 pounds per squrare inch.
This is the method preferred nowadays by many professional and licensed plumbing contractors for drain cleaning services in Los Angeles. High pressured hose with a special nozzle connected to it is used to release a powerful stream of hot water through the drain.
