Product-led drain guidance
Find the right drain unblocker for the actual blockage.
Compare liquids, gels, plungers, snakes, rods, pressure jetters and inspection tools. Start with the symptom, rule out unsafe DIY work, then choose what is designed for the job.

Start with the affected drain
The same product is not appropriate for every fixture, material or symptom.
Start with direct, controllable options
For one slow sink, check visible debris and the trap before choosing a product. A sink plunger or small hand auger can address a nearby soft obstruction.
Drain diagnosis matrix
Match the pattern before the product
This reference connects an observable symptom with the shallowest likely location, the next useful decision and the point at which DIY work should stop. It cannot confirm a concealed pipe condition.
| Observed pattern | Possible location | Useful next decision | Stop condition |
|---|---|---|---|
| One sink or basin is slow | Stopper, trap or short local branch | Remove visible debris, then choose trap cleaning or controlled sink plungingDiagnose a blocked sink | Stop if another fixture reacts, a joint leaks or a chemical may be present |
| One toilet rises after flushing | Toilet trap, soft obstruction or lodged object | Stop flushing and assess whether a flange plunger is suitableCheck a rising toilet | Stop if the bowl is near the rim, an object is suspected or another fixture backs up |
| Several fixtures gurgle or back up | Shared branch, private drain or public sewer | Minimise water use and establish ownership before arranging clearanceMap a shared-line problem | Do not dose each fixture or keep testing with more water |
| An outside gully is full or overflowing | Surface debris, local gully trap or a surcharged downstream system | Remove only accessible surface debris and identify whether the flow is rainwater or sewageAssess an outside overflow | Keep away from sewage, deep chambers and heavy covers |
| Flow stopped during freezing weather | Exposed pipe with frozen standing water, or an unrelated blockage | Isolate the fixture and use controlled thawing only where the pipe is safely accessibleCompare frozen-pipe signs | Never use flame or boiling water; check for leaks as the pipe thaws |
| The blockage returns at the same point | Retained deposit, roots, poor fall, displaced joint or collapse | Move from repeated clearance to a documented condition surveyInvestigate recurrence | Do not assume restored flow means the defect is repaired |

When another product is not the answer
Several affected drains, sewage backup, recurring obstruction or suspected damage needs a drainage professional with the right diagnostic and clearance equipment.
- Drain unblocking and water jetting
- CCTV and sewer camera inspection
- Root cutting, descaling and Picote cleaning
- Relining, patch repair or excavation
