Hydro-jetting uses high-pressure water to clear blockages and clean the inside of drain and sewer lines. It's highly effective for grease, scale, roots, and debris—and it cleans the pipe walls, which can help prevent future clogs. We use professional-grade equipment sized for residential and light commercial lines.
How we help
We feed a specialized hose with a jetting nozzle into your line and run high-pressure water through it. The force breaks up blockages and scours the pipe interior. We may recommend a camera inspection first to ensure the line can safely handle jetting.

Common causes include hair and soap in showers, food grease in kitchen sinks, foreign objects, or buildup deeper in the line—sometimes tree roots in the sewer. Store-bought chemicals rarely fix the real problem and can damage pipes. Drain Doctor Covina diagnoses with video pipe inspection when needed, then clears or repairs the line properly. Call (626) 332-9984 for help.
Stop using fixtures that tie into the same line to avoid backups. For a slow draining sink or stubborn shower clog, professional drain cleaning or hydro jetting clears the blockage safely. Drain Doctor Plumbing & Rooter offers same-day service in Covina and nearby—call (626) 332-9984.
Gurgling toilets, multiple drains acting up at once, sewage smells, or water backing up in tubs or floor drains can mean a main line problem. Sewer line inspection with a sewer camera finds the cause—whether it is a clog, bellied pipe, or root intrusion—so Drain Doctor Covina can recommend sewer repair or cleaning. Call (626) 332-9984 to schedule.
