Why a log helps
Drain problems are easy to forget between episodes. By the time a plumber arrives, most people remember only that the shower was slow last month. But the pattern matters: a single slow sink points to that fixture, while a tub that gurgles every time the washing machine drains points further down the line, often to the main sewer lateral.
In older Fullerton homes with clay or cast-iron laterals, a written history also helps separate seasonal root problems from grease or scale. It is the cheapest diagnostic tool you have.
The log itself
| Date and time | Fixture affected | What happened | What was running at the time | What you did |
|---|---|---|---|---|
What to note each time
- Which fixture showed the problem first: sink, tub, shower, toilet, floor drain or cleanout.
- Whether other fixtures were affected at the same time.
- What was draining a moment before: washing machine, dishwasher, shower or toilet.
- Sounds such as gurgling, bubbling or a toilet bowl rising and falling.
- Any odor near drains or the outdoor cleanout.
- Whether the problem cleared on its own, with a plunger or after a service call.
Reading your log
- IfEntries involve only one fixtureThenThe clog is likely in that fixture's trap or branch line.
- IfEntries involve several fixtures at once, especially the lowest onesThenThe main line is likely involved. Mention this first when you call.
- IfProblems cluster after laundry or dishwasher runsThenA partly blocked line is struggling with large volumes of water.
- IfEntries repeat at similar times of yearThenAsk whether roots could be the cause and whether a camera inspection makes sense.
Bring the log and ask
- Does this pattern point to a branch line or the main lateral?
- Would a camera inspection help confirm the cause?
- Is this a buildup the jetter can remove, or something that needs repair?
Common questions
How long should I keep the log before calling?
If drains are only a little slow, a few weeks of notes is plenty. If anything backs up into the house, call right away and fill in the log afterward.
Should I log the dates of past cleanings too?
Yes. Note who cleared the line, how, and what they found. That history is often the most useful part.
Can I share the log with a plumber before the visit?
Many plumbers appreciate a photo or summary of it when you first describe the problem.
