TL;DR
Commercial drain jetting uses high-pressure water to strip fat, grease, scale and root ingress from the full internal diameter of a pipe — not just punch a channel through the blockage the way manual rodding does. It's the standard maintenance approach for restaurants, cafés, care homes, retail units and managing agents across Basingstoke who need drains that stay clear between visits rather than cleared once and left to fail again. If your business drains back up repeatedly, or you want to move from reactive call-outs to scheduled maintenance, arrange a commercial site visit online.
Who Actually Needs Commercial Jetting
Basingstoke has a genuinely broad commercial base — from the offices and head-office functions around Basing View to the retail and food units at Chineham Shopping Centre, plus the industrial and trade premises on Houndmills Industrial Estate. Drain jetting tends to matter most for:
- Food businesses — kitchens, cafés and takeaways generate fats, oils and grease (FOG) that solidify inside pipework. Thames Water, the sewerage authority for the area, actively discourages FOG being poured down drains precisely because it's one of the leading causes of blockages in both private and public sewers.
- Care homes and healthcare premises — wipes, continence products and high water usage put unusual pressure on drainage systems that can't afford unplanned downtime.
- Retail and hospitality units — shared drainage runs in retail parks and parades mean one tenant's blockage can affect neighbouring units, so keeping your own run clear matters for goodwill as much as compliance.
- Managing agents and landlords — commercial leases commonly place drainage maintenance obligations on the managing agent, and a documented jetting schedule is useful evidence that those obligations are being met.
Signs Your Business Drains Need Attention
Reactive plumbing is expensive because it usually means trading has already been disrupted. Watch for:
- Slow-draining sinks or floor gullies that get worse through the day, especially during service
- Gurgling from floor drains or WCs when other fixtures are used
- Recurring smells around external gullies, especially near kitchen extract or grease trap areas
- A blockage that clears with rodding but returns within weeks — a strong sign the pipe walls are coated with grease or scale that rodding hasn't touched
- Multiple call-outs to the same drain run over a short period
High-Pressure Jetting vs Rodding
Rodding pushes a flexible rod through the blockage to create a channel for water to flow again. It's effective for a single, discrete obstruction, but it doesn't clean the pipe walls. Jetting works differently: a hose delivers water at high pressure through a nozzle that cuts forward and sprays back against the pipe wall as it's drawn through, scouring grease, scale and root intrusion off the full circumference of the pipe, not just the middle of the flow. For a one-off domestic blockage, rodding is often enough. For commercial kitchens and drains under continuous heavy use, jetting is the more thorough option because it addresses the build-up causing repeat blockages, not just the immediate obstruction. Our commercial drain jetting service sits within our wider high-pressure drain jetting service, which also covers smaller domestic jobs.
What to Expect from a Commercial Site Visit
Before jetting, it's standard practice to run a CCTV inspection to confirm the pipe's condition and route. This matters commercially for two reasons: it avoids jetting into a pipe that's already structurally compromised, since high pressure can worsen an existing crack, and it gives you a baseline record of pipe condition that's useful for lease compliance or insurance purposes. From there, the engineer jets the confirmed run and can advise on a sensible interval for repeat visits based on what the survey and jetting actually found — some kitchens need frequent attention, others get by with an annual clean, and it depends entirely on usage.
FAQs
How often should commercial drains be jetted?
There's no universal answer — it depends on usage, what's going down the drain, and pipe condition. A high-volume kitchen typically needs more frequent attention than a small retail unit, and several food outlets sharing one drainage run will coat that run with grease faster than a single office block on its own connection. The most reliable way to set an interval is a CCTV survey plus an initial jet: what the camera shows about how quickly the pipe walls are building up tells you far more than any generic schedule. From there the interval can be reviewed at each visit — tightened if the run is coating up quickly, relaxed if it comes back clean.
Can you work outside normal trading hours?
We can discuss scheduling around your trading pattern when you get in touch — every business's constraints are different, so it's best to raise your requirements directly through the enquiry form rather than assume a fixed arrangement.
Will jetting damage older pipework?
This is exactly why a CCTV survey typically comes first for commercial jobs. If a pipe shows signs of significant deterioration, that gets flagged before jetting begins, and repair options can be discussed instead.
Does jetting deal with grease traps too?
Jetting clears the pipework connected to a grease trap; the trap itself needs separate emptying and maintenance as part of your own operational routine. Ask when you enquire if you're not sure where the boundary sits for your system.
