A slow drain is a warning. By the time it's a complete blockage, you're losing use of your kitchen, bathroom, or laundry room entirely. Masters Plumbing Service's drain techs in Hercules, CA use hydro-jetting equipment rated to 4,000 PSI and CCTV pipeline cameras to locate, clear, and document the obstruction — not just temporarily push it further down the line.

Retail drain products and inexperienced plumbers share one problem: they treat the symptom, not the cause. Our approach combines the right equipment with the right diagnostic process.
Our truck-mounted hydro-jetting units propel water at up to 4,000 PSI through a rotating nozzle that scours pipe walls clean — removing grease buildup, scale, and soft root intrusions in a single pass. Unlike augers, jetting leaves the pipe interior clean rather than just piercing a hole through the clog.
Before recommending any clearing method, we run a push-rod camera into the drain to visually confirm blockage type and location. Grease accumulation 30 feet in looks different from a root ball at a joint or a collapsed section — and each requires a different response.
Whether it's a backed-up bathroom sink or a full house sewer drain stoppage, our team carries the right nozzle sizes and cable diameters for the specific pipe we're clearing.
Our written service report notes the blockage type, location, method used, and any structural observations from the camera run. You walk away knowing the state of your drain system, not just that the water is flowing again.
From a slow bathroom sink to a full main-line stoppage affecting every fixture in the house, our drain techs in Hercules, CA have the equipment and training to clear it.
Kitchen drains accumulate FOG — fats, oils, and grease — that solidifies on pipe walls and progressively narrows the line. We use a combination of a cable auger to break the initial plug and a hot-water hydro-jet pass to scour the residual grease film. For commercial kitchens, we also service grease interceptors and document cleaning for inspection records.
Chronic slow bathroom drains often point to a partially closed p-trap, a buildup on the overflow plate mechanism, or a drain arm pitched incorrectly. We clear the immediate clog and identify if a mechanical fix is needed to prevent fast recurrence.
Root intrusion at pipe joints is the leading cause of main sewer blockages in homes over 20 years old. Our electric root cutter attachment on the sectional cable removes the root mass; we then scope again to confirm the line is clear before pulling equipment.
Basement floor drains and laundry room drains often go years without cleaning and can develop sediment, lint, and mineral scale blockages. We clear these drains with an electric snake and flush thoroughly to confirm full flow before closing out the job.
Restaurants, multi-family buildings, and homes with chronic grease or root problems benefit from scheduled hydro-jet maintenance on a 12–24 month cycle. We map the drain system, document baseline camera footage, jet the lines, and re-scope to confirm clean pipe walls. This approach prevents emergency backups rather than reacting to them.
Sometimes the question isn't just "why is this draining slowly" but "what is the actual condition of this pipe system." We run a recorded CCTV inspection with distance markings and provide a written report noting blockage types, root intrusion points, joint offsets, pipe material, and any visible structural defects.
We don't show up and start snaking blind. Our approach uses a camera-first diagnostic protocol to confirm what we're clearing before selecting the method.
Your description lets us load the right equipment before we leave the shop. Main line call vs. single kitchen drain is a different tool setup — knowing ahead saves time on site.
Before clearing anything, we run a CCTV camera into the line to see blockage type, location, and pipe condition. This prevents treating a structural pipe failure with a jetting pass that won't hold.
If the camera reveals a structural problem that will require repair rather than just clearing, we tell you that now rather than letting you pay for a clearing that won't last.
If anything was found during the camera run that warrants monitoring or repair, it's noted in the written report so you have a record — useful for planning future maintenance or a repair conversation.

Called about a kitchen drain that three other plumbers had snaked without long-term success. Masters Plumbing Service ran a camera first and found grease buildup 28 feet in, past where any hand snake reaches. Hydro-jetted it, re-scoped to confirm clean, and the drain has run perfectly in the months since.
Main line backed up completely on a Sunday. Found Masters Plumbing Service and they came within 2 hours. Camera found a 3-inch grease plug combined with roots at a joint. Cleared both with cable and jetter, sent me the scope video via email. Super transparent process.
