Homes: clean on signs, not the calendar
A well-laid domestic drain carrying normal household waste can run for years without attention. Cleaning it for the sake of it adds little. What matters is noticing when it starts to struggle: water that drains slowly from several fixtures, gurgling from plugholes, smells from gullies or chambers, or a manhole that holds more water than it should.
Some properties are more prone to build-up. Older clay pipes with many joints, drains near large trees, runs with a shallow fall and households that cook a lot with oil may benefit from occasional jetting, particularly if the drain has blocked before.
Signs a drain clean is due
- Slow drainage from more than one sink, bath or shower.
- Gurgling from plugholes or toilets when another appliance empties.
- Unpleasant smells outside near gullies or chambers.
- Water level rising in an inspection chamber after heavy use.
- Previous blockages in the same part of the system.
Commercial kitchens and hospitality
Restaurants, takeaways, pubs, clubs and hotel kitchens send far more fat, oil and grease into their drains than a home. Even with good kitchen practice, it cools and hardens on the pipe wall. A planned jetting schedule, set by how quickly previous inspections showed build-up, keeps the line open and avoids a blockage in the middle of trading.
Grease traps and interceptors need their own maintenance, and keeping them working reduces how often the drain itself needs attention. Our guides to commercial kitchen grease management and commercial drainage maintenance planning cover this in more depth.
Shops, offices and commercial buildings
Buildings with shared toilets and staff kitchens usually sit between the two. Many only need attention when a problem appears, but sites with a history of blockages, or where downtime is costly, often benefit from a periodic inspection so issues are found before they close a toilet block.
Setting an interval that makes sense
- Start with a CCTV survey or inspection to see the current condition.
- Clean the line and note how quickly it fouls up again.
- Set the next clean just before build-up would start to cause trouble.
- Review the interval if the kitchen, menu or occupancy changes.
- Keep a simple record of cleans and call-outs to spot patterns.
Everyday habits that reduce cleaning
Wipe greasy pans before washing them, use sink strainers, keep wipes and sanitary products out of toilets and clear leaves from outside gullies in autumn. None of this replaces a clean when one is needed, but it stretches the time between them. Our guide to what not to put down your drains has a fuller list.

Questions we get asked
Do household drains need cleaning every year?
Usually not. Clean when there are signs of build-up or after repeat blockages, rather than on a fixed annual schedule.
How often should a restaurant drain be jetted?
It depends on the kitchen and how quickly grease builds up. Inspection after a clean is the best way to set a realistic interval.
Can I clean my own drains?
Regular hot water flushes and strainers help. For build-up along the pipe, professional jetting is what actually removes it.
Does drain cleaning include a camera check?
It can. A camera run after cleaning shows whether the pipe is sound and helps set future intervals.
