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 Lagunitas, CA use hydro-jetting equipment rated to 4,000 PSI and CCTV pipeline cameras to locate, clear, and document the obstruction β 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 β 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.
A camera inspection saves you money by showing us exactly what we're dealing with. It also protects you from paying to clear a blockage that's actually hiding a structural pipe failure that will recur immediately.
We clear kitchen drains, bathroom sink and shower drains, floor drains, laundry drains, and main sewer lines. Our equipment scales from a 1/2" kitchen drain line to a 6" commercial main β same certified technician, same professional-grade tools.
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.
Not every blocked drain is the same problem. Here's how our team approaches each type β with the specific tools and technique that actually resolve it.
Grease blockages in kitchen drain lines often occur 10β40 feet from the drain opening, past the p-trap, where the line cools and FOG solidifies. Our jetting equipment reaches and clears these deposits where a plunger or retail product cannot.
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.
When multiple fixtures are draining slowly or backing up simultaneously, the blockage is typically in the main sewer line β the 4" or 6" pipe that carries all household waste to the municipal main or septic system. We access the main line through the cleanout, run a CCTV camera to identify the obstruction type, then clear with a sectional cable machine or hydro-jetter depending on what we find.
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.
A preventive jetting program documented over multiple visits gives you both clean pipes and a camera record of pipe condition over time β useful for catching structural deterioration before it causes an emergency.
Our inspection reports are accepted by real estate attorneys, home buyers, and insurers as documented evidence of drain system condition. If you're buying or selling a home in Lagunitas, a pre-purchase drain scope is one of the best $300 you can spend.
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 β knowing ahead saves time on site.
The camera also gives us the distance to the blockage and confirms the pipe diameter β both factors in selecting the right clearing method and nozzle size.
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.
After clearing, we run the camera a second time to confirm the pipe is open to full diameter. You see the before-and-after footage. We provide a written service summary and our drain clearing warranty.

My kitchen drain had been running slow for months and completely stopped the night before Thanksgiving. Masters Plumbing Service had a tech out same morning, ran the camera, and found a 15-foot grease accumulation in the drain arm behind the wall. The jetter cleared it in about 20 minutes. The footage before and after was dramatic β I could actually see the pipe walls go from coated to clean. No recurrence four months later.
All three bathrooms drained slowly and the lowest floor toilet gurgled every time an upstairs fixture ran β classic main line partial blockage. Masters Plumbing Service's tech accessed the cleanout, ran the camera, and found root intrusion at a clay tile joint about 40 feet from the house. He cut the roots with the root cutter attachment and re-scoped to confirm clear flow. Also noted a joint offset at 68 feet that we'll need to line eventually β good to know before it becomes a full backup.
Had a pre-purchase drain scope done on a home we were buying. Masters Plumbing Service's tech ran every accessible drain and the main sewer line with the camera, gave us a written report with timestamps and footage. Found a small bellied section in the main line that the seller agreed to repair before closing. Worth every penny for the negotiating power alone.
