On October 14, 2026, John Ciampoli Plumbing serviced two floor drains at a commercial kitchen in San Diego. Both backed up during testing. The technician used mechanical drain-cleaning equipment, repeated the cleaning and water tests, and checked drainage through several dishwasher cycles before recording restored flow. The job illustrates why the service report should describe both the work performed and the checks that followed.
What happened at this San Diego kitchen?
The technician tested the kitchen drains and observed backups at two floor drains. The service record describes mechanical drain cleaning, repeated passes and water tests. This was not a hydro-jetting visit.
After clearing the lines, the technician ran several dishwasher cycles as part of the final verification and documented restored drainage. Those checks describe the condition at completion; they do not guarantee that a drain can never back up again.
What did the technician confirm—and what remains unknown?
The record supports a specific result: the two drains were cleared and drainage was restored during the recorded tests. It also states that no material was retrieved. A successful clearing does not, by itself, identify the obstruction.
That distinction matters when planning future work. This report does not establish a grease blockage, root intrusion, a broken pipe or a need to replace the drains. If a problem returns, share this service history so the next assessment can build on what was actually observed.
What should a kitchen manager tell dispatch?
Start with the city, the affected work area and what was happening when the backup appeared. Report whether one drain or several are affected, whether water is still rising and which equipment was operating. You do not need to diagnose the pipe before calling.
If water is already backing up, do not run more equipment merely to reproduce the problem for a photo. Keep staff away from the affected area and follow your facility's procedures while arranging service.
Use our commercial plumbing service-request checklist
- Which floor drains, sinks or other fixtures are affected?
- When did the backup start, and has the same issue occurred before?
- Was a dishwasher or another water-using appliance running?
- Can the technician reach the affected drains and work area?
- Who can authorize the work and coordinate any interruption to kitchen operations?
What should the completion report include?
Ask which drains were worked on, what method was used and what the technician observed during the final tests. If material was recovered or another problem was found, have that finding recorded separately from a suspected cause.
For this job, the repeated water tests and dishwasher cycles are the useful details. For another property, the appropriate checks depend on the fixtures, access and findings. Clearing a blockage also does not establish that an unrelated leak has been repaired.
