Build the condition record
Build the condition record
- Note whether the basin is fully stopped or merely slow, and when that changed.
- Listen for gurgling at this or another fixture without running an intentional stress test.
- Remove only loose material at the visible stopper if no disassembly is involved.
- List cleaners, tools, hot water, or prior service already attempted.
Why the pattern matters
Why the pattern matters
An isolated slow sink can involve the stopper, trap, branch, venting, disposal, or something farther downstream. Pouring chemicals into the line can create an exposure for the person who later opens it and can make the original condition harder to assess. Report anything already used.
Questions the record should answer
Questions the record should answer
- What access point will be used and what surface must be protected?
- Will the first method retrieve, push, cut, or dissolve material?
- How will the provider decide the line is clear rather than temporarily open?
- What recurrence would justify broader investigation instead of repeating the same visit?
