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 Shell Knob, MO 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.
Not every blocked drain is the same problem. Here's how our team approaches each type — with the specific tools and technique that actually resolve it.
Grease blockages in kitchen drain lines often occur 10–40 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.
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.
Floor drain traps can dry out and allow sewer gas into the structure if the drain isn't used regularly. We clear blockages, re-water the trap, and can install a trap primer if the drain is prone to drying in Shell Knob's climate.
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.
The camera also gives us the distance to the blockage and confirms the pipe diameter — both factors in selecting the right clearing method and nozzle size.
Based on the camera findings, we present you with a flat-rate quote and explain exactly which method we're using — electric auger, hydro-jet, root cutter — and why. No work begins until you approve.
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.

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 — 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 — 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 — good to know before it becomes a full backup.
