Why a log helps
A drain that gurgles only after laundry, a warm spot that appears in the evening, a toilet that runs at night: these clues tend to disappear the moment someone arrives to look. A short record of when and where they happened often points straight at the cause.
Use this log for problems that are not emergencies yet. If water is spreading, sewage is rising or you smell gas, stop logging and act: shut off the water, keep away from sewage, or leave and call 911 or SoCalGas from outside.

Common questions
How long should I keep a log?
Until you see a pattern or the problem is fixed. A week of entries is often enough for an intermittent issue.
Should I share the log with the plumber?
Yes. Send a photo of it before they arrive or hand it over at the start of the visit.
Is it worth logging small drips?
Yes, especially under sinks or near the water heater. Small leaks tend to grow.
