A slow drain is more than an inconvenience — it's a warning. Left unaddressed, partial blockages become full clogs, and full clogs become sewage backups that can cause serious water damage. At One Time Plumbing Inc., we don't just poke at the symptom — we find the cause and clear it completely, the first time.

​

For over 20 years, we've been clearing drains for homeowners across San Jose, Campbell, Los Gatos, and the surrounding South Bay. We use professional-grade equipment that goes far beyond anything you'll buy at a hardware store, and we stand behind our work with the kind of care that comes from two decades of doing this right.

​

Whether it's a kitchen sink packed with grease, a bathroom drain choked with hair and soap scum, or a main sewer line backing up across multiple fixtures — we start by identifying the actual source of the blockage rather than guessing.

​

For stubborn or recurring blockages, hydro-jetting is the most effective solution available. A high-pressure water jet scours the interior walls of your pipes clean — removing grease buildup, scale, mineral deposits, and debris. Before recommending any major repair, we look inside the pipe with a sewer camera — giving us and you a real-time view of exactly what's happening.

​

Tree roots are patient. They find the smallest crack in a sewer pipe and grow into it over years. Our rooter service cuts through root intrusions and restores flow — and we'll advise you honestly on whether pipe lining or spot repair makes sense as a long-term fix.
