The difference
What each option actually means
Repeatedly restoring flow may leave an underlying defect unidentified.
The trade-offs
Inspection can help explain the cause when blockages return, although it may not be necessary for every isolated incident.
How to decide
Consider frequency, severity, pipe access and the value of confirming the condition.
Before choosing
A plumber should assess suitability, condition, access and applicable requirements. Product or repair recommendations made without seeing the property are preliminary. Ask for the proposed scope, exclusions and relevant warranty details before approving the work.
