A drain that works for a week and slows again is telling you something. The previous clearing may have opened a path through the blockage without resolving everything in the line, or there may be a condition that needs a different approach.

Write down the pattern
Note the first fixture affected and what happens elsewhere. Does the kitchen sink slow by itself, or does a downstairs drain rise when an upstairs fixture runs? Record how long the last clearing lasted and whether the symptom returned gradually or suddenly.
Share what has already been tried
Give the plumber any previous camera recording, repair invoice or description of the clearing method. Mention drain chemicals even if they did not help. Repeating a treatment without that history can waste time and expose the next person working on the drain to an unexpected product.
Separate clearing from investigation
Cable clearing, water jetting and camera inspection do different jobs. A camera can help review visible pipe conditions when access and the line’s condition allow it. A blocked or dirty line may need work before a useful view is possible. Restored flow alone does not establish that every section is sound.
Ask what the findings support
Request an explanation of what was found, what remains uncertain and why the next step fits the problem.
- Is further cleaning appropriate?
- Is there evidence of a defect needing repair?
- Would monitoring be reasonable, and what should trigger another call?
If wastewater is rising
Stop using the affected fixtures and call. Keep clear of sewage and water near electrical equipment. Do not keep adding water to test whether the blockage has finally cleared.
Compare the return of the symptom with the previous result
“It clogged again” becomes more useful when you add a timeline. Record the date of the last service, which fixtures improved, how long they worked normally and how the current symptom began. A drain that never returned to normal and one that worked for months should not be presented as the same history. Share what you actually observed without deciding which treatment should be repeated.
Include changes in occupancy, appliance use or renovation work if they coincided with the problem. They are context, not proof of a cause. If a previous contractor recommended further investigation, provide that recommendation and say whether it was carried out. This prevents an unresolved item from disappearing between visits.
Use the fixture pattern to describe the investigation area
A single slow basin, several fixtures affecting one another and wastewater appearing at a low drain give the office different information. List which fixtures are affected and which still seem normal. Do not operate unaffected fixtures to deliberately force another backup; use the history you already have.
City of Dieppe: sewer-backup causes describes how a blocked or damaged pipe can redirect wastewater into a building. This illustrates possible mechanisms, not the diagnosis of your Saint John property or the location of responsibility. If a wider sewer problem is suspected, ask what evidence supports that concern and whether the water utility or another responsible party needs to be involved.
Ask for evidence with a stated limit
RIDGID: SeeSnake inspection-system operator’s manual describes equipment used to view pipe interiors. A recording is useful when the inspected route, direction and access point are clear. Ask the technician to identify the section shown, any point the camera could not pass and the conditions affecting visibility. A dark image or a distance reading without context is not a complete repair plan.
Request the distinction between an observed condition and a possible explanation. Material visible in the line, a restriction that prevents progress and a confirmed damaged section lead to different decisions. Ask whether cleaning is needed for a better inspection and whether the proposed repair location has been established sufficiently for the work being recommended. Do not infer that an unviewed section is sound because the visible part looks clear.
Choose a next step with a reason to reassess
A proposal should explain whether the immediate goal is clearing, obtaining better evidence or repairing a confirmed condition. If monitoring is suggested, ask what normal use is permitted and what change should trigger a call. If a repair is proposed, clarify access, excavation or opening requirements and the restoration responsibilities before agreeing to it.
Keep the previous recording and report even after a later visit. They help compare the same area over time. Avoid adding chemical products between appointments without discussing the situation, and disclose anything already used. A successful flow check is a useful result for that visit; it is not a guarantee against future blockages or proof that every buried connection has been inspected.
