Test the drains together
- Start with the problem fixture.Run the drain that was clogged at full flow for a minute and watch it empty.
- Run the lowest drains.Fill and drain the lowest tub or shower, then watch for any water rising elsewhere.
- Flush every toilet.Flush each one in turn while someone watches the tub or shower nearest the sewer exit.
- Run a big load.If the main line was cleared, start the washer's drain cycle or a full dishwasher before the plumber leaves.
Look around
- Cleanout cap is back on, tight and undamaged
- Any pulled toilet is reset, does not rock, and does not leak at the base
- Traps under sinks are dry at the slip nuts after running water
- Floors, rugs and the cleanout area are cleaned up
- No standing water left in the yard around the cleanout
- Tools and cable debris are removed
Ask before they go
- What was the blockage, and where was it?
- Did you see roots, grease, scale, wipes or pipe damage?
- Do you recommend a camera inspection, and why?
- Is there anything I should stop putting down the drain?
- If it clogs again, what should I tell the next plumber?
Check the invoice
| Should show | Why |
|---|---|
| Contractor name and CSLB license number | Ties the work to a licensed business |
| Which line was cleared and from where | Useful history if the clog returns |
| Method and equipment used | Helps compare future quotes |
| What was found | Records roots, damage or a foreign object |
| Any guarantee terms | Defines what happens if it re-clogs |
Watch for these over the next few weeks
- First day
- Normal use, including laundry; note any gurgling or slow drains.
- First week
- Watch the lowest drain after heavy water use, like several showers in a row.
- First month
- If the same symptoms return, log them and contact the contractor with the invoice in hand.
- Long term
- If roots were found, note the date; root backups often follow a cycle.
Common questions
The drain works but still gurgles. Is that normal?
A little gurgling right after clearing can settle down. If it continues, mention it; it can point to a venting issue or a partial restriction.
Why test with the washer?
It sends a large volume of water quickly, which reveals a main-line restriction that a single sink might not.
What if the plumber has already left?
Run the tests yourself and write down the results. Contact the contractor promptly if something is wrong.
