Key takeaways
- Homes often do well with one or two visits a year
- Busy kitchens may need monthly service
- Older pipes, big trees and heavy use shorten the interval
- The first year of visits shows how fast buildup returns
There is no single answer
How often a drain needs cleaning depends on what goes down it and what it is made of. A guest bathroom used once a week and a restaurant dish pit used for twelve hours a day are not the same job.
The best approach is to start from a sensible default and adjust once the first visits show how quickly buildup returns.
Common starting points
A typical house: once or twice a year. A condo or townhome: once or twice a year. A rental or short-term rental: every one to three months. An office or shop: quarterly. A restaurant: monthly for the grease line, with the trap on its own schedule.
These are planning figures, not rules. Our Interval Calculator and Plan Builder turn them into a suggestion for your property.
What shortens the interval
Heavy use, grease, long hair, hard water, older iron or clay pipes, big trees near the sewer line and a history of clogs all point to more frequent visits. A restaurant with a fryer will need more than an office with a coffee machine.
A camera look at the line often shows whether yearly is enough or whether roots or scale call for more.
What lengthens it
Newer PVC plumbing, light use, drain screens that are emptied regularly and good habits at the sink can stretch the interval. Fewer visits is fine if the notes show the drains are staying clear.
The point of recording each visit is to learn that, so the schedule fits the property instead of a generic rule.
Quick answers
Can I clean drains myself between visits?
Yes. Simple habits help a lot. See our habits checklist.
Is yearly ever too little?
For a house with big trees or old iron pipes, twice a year may suit better. The notes will tell.
