Clear grease, roots, sludge, and recurring clogs with professional hydro jetting in Covina, CA. Call Flash Plumbing Inc. for a camera inspection and free quote.
Homeowners often tell us that a drain was cleared recently but it never felt completely normal afterward. It may have drained for a while, then slow down again. Sometimes our clients report hearing gurgling noises from another fixture or notice an odour coming from the kitchen sink. A drain snake can be useful when something is caught in the line. The problem is that it may only create an opening through grease, sludge, or other buildup. Water starts moving again, but much of the material is still there.
Hydro jetting cleans more of the pipe wall. We often recommend it for stubborn clogs, recurring backups, grease-heavy kitchen lines, and main sewer lines affected by roots or years of buildup.
Restaurant kitchens, multi-unit buildings, and other high-use properties rely on hydro jetting when drain lines need a deeper cleaning than standard clearing can provide. We start with a camera inspection, explain what we find, and schedule the work around your business hours when possible.
Hydro jetting uses a hose and specialized nozzle to send pressurized water through a drain or sewer line. The nozzle directs water forward and backward. The forward stream helps break apart the obstruction, while the rear-facing streams help pull the hose through the pipe and wash loosened debris out of the line. Our advanced equipment can produce pressure up to 4,000 PSI, but that does not mean every pipe receives the maximum pressure. Our team will adjust the setup based on the pipe material, its condition, and what needs to be removed. A newer PVC line may be handled differently from an older clay or cast-iron pipe. Grease buildup may also call for a different nozzle than tree roots or mineral scale.
That is why a video inspection matters.
These signs point to buildup that a drain snake usually cannot fully clear:
