What is commercial drain jetting?
Drain jetting uses high-pressure water jets to dislodge blockages and scour the inside walls of your pipes clean.
Our engineers deploy specialised equipment, feeding a hose fitted with a jetting nozzle into your drainage system through a manhole or inspection chamber, and pressurised water does the rest.
The pressure is adjustable depending on what we’re dealing with. A grease-clogged kitchen drain needs a different approach to a root-infested sewer running beneath a car park.
Our high pressure drain jetting units can deliver water at pressures up to 4,000 PSI, which is enough to cut through hardened fat deposits, tree roots, scale buildup, encrustation, concrete residue, and compacted silt that’s been sitting in your pipes for years.
Our advanced jetting equipment is significantly more powerful than domestic units you might have seen advertised online.
The truck-mounted units carry their own water supply and can reach drainage runs hundreds of metres long, which is why they work on the kind of large-diameter pipe networks that commercial and industrial properties rely on.
Why commercial properties need drain jetting
Your business puts more demand on its drainage system in a single day than most homes do in a month.
High footfall through toilets, grease and food waste from kitchens, process waste from manufacturing, surface water from large roof areas and car parks. All of it funnels through your pipes, and over time it builds up.
The buildup rarely causes a dramatic failure straight away.
What happens instead is a gradual narrowing of the pipe bore as grease coats the walls, silt settles in low spots, and scale accumulates in hard water areas.
Flow slows down. Drains start backing up during peak usage, causing flooding in toilets and kitchen areas. Foul smells develop. And then one day the system reaches a tipping point and stops working entirely, usually at the worst possible moment.
Reactive drain clearing with rods or a domestic-grade jet might get things moving again, but it doesn’t remove the buildup coating your pipe walls.
Within weeks or months, you’re calling someone out again. Commercial drain jetting strips the pipes back to their original bore, which means the blockage doesn’t just clear temporarily. It stays clear.
The cost of doing nothing on your drains
A planned jetting visit is the most cost-effective approach to drainage maintenance.
Factor in lost trading hours, water damage to stock or equipment, contamination risks, customer complaints, and potential fines from Environmental Health, and the maths becomes obvious.
Businesses that schedule regular jetting spend less on drainage overall than those that wait for emergencies.
How commercial drain jetting works with Clark Drainage
Our process is straightforward and we’ve refined it to cause minimal disruption to your operations while delivering long-lasting results.
Step 1: Assessment
You call us or fill in the contact form.
We’ll ask about your property type, the nature of the drainage issue (or whether this is a maintenance visit), and when access is available.
For severe blockages, our fast service means we can usually be on site within one to two hours.
Step 2: CCTV pre-inspection
Before jetting, we run a CCTV drain survey wherever possible.
This tells us exactly what’s causing the blockage, where it is, and the condition of your pipes.
Jetting a pipe that’s already collapsed or badly cracked can make things worse, so the camera check protects you from unnecessary damage.
Step 3: High-pressure jetting
Our engineer selects the right nozzle and pressure setting for your pipes.
The jetting hose goes in through a manhole or inspection chamber, and the high-pressure water jet works its way through the system for effective blockage removal, flushing debris downstream safely and efficiently.
For grease-heavy drains, we use rotating nozzles that scour the pipe walls clean. For root ingress, we use cutting nozzles that slice through roots without damage to surrounding pipework.
Step 4: Post-jetting verification
Once the jetting is complete, we run the CCTV camera through again to confirm the blockage is fully cleared and the pipe walls are clean.
This non-invasive verification means you see the before and after footage yourself, so there’s no guesswork about whether the job is done properly.
Step 5: Report and recommendations
You receive a written report covering what we found, what we did, and whether any further work is needed.
If the camera reveals structural damage that jetting alone can’t fix, we’ll explain your options honestly and quote for any additional work such as drain repair or relining.
What commercial drain jetting removes
High-pressure water jetting deals with the full range of blockage types that affect commercial drainage systems, including even the most stubborn of blockages. Here’s what our drain jetting services clear on a typical week.
Fats, oils, and grease (FOG)
The single biggest cause of commercial drain blockages in the UK.
Restaurants, pubs, hotel kitchens, canteens, and food processing facilities all produce FOG waste that solidifies in drainage pipes. Standard cleaning methods push grease further down the line, but jetting strips it from the pipe walls completely.
Combined with regular grease trap cleaning, scheduled jetting keeps kitchen drains flowing freely between services.
Tree root ingress
Roots find their way into pipes through cracked joints and small fractures, then grow until they fill the pipe bore entirely. Jetting with a cutting nozzle removes the root mass and restores full flow.
If the roots have caused structural damage to the pipe, we’ll pick that up on the CCTV survey and recommend a permanent repair.
Silt, sediment, and debris
Surface water drains, gullies, and culverts on commercial properties collect silt and debris from car parks, loading bays, and landscaped areas.
Motorway drainage is also vulnerable, with runoff carrying grit and debris into the system. Construction sites are particularly bad for this, with aggregate and soil washing into pipes during groundworks, and our jetting can remove concrete residue that has hardened in place.
Jetting flushes all of it out and prevents the gradual silting up that reduces your system’s capacity over time.
Scale and mineral buildup
In hard water areas, limescale and mineral encrustation gradually narrow the inside of your pipes. It’s a slow process, but after a decade or two the reduction in bore can be significant enough to cause flow problems and even flooding.
High-pressure drain jetting is the most effective way to remove scale deposits that chemical treatments and mechanical cleaning struggle with.
Wet wipes and sanitary products
Despite the signage, people flush what they shouldn’t.
In offices, hotels, and public-facing buildings with high toilet usage, wet wipe blockages are common.
Jetting breaks up the compacted mass and clears the pipe completely, whereas rodding often just pushes the problem further along.
Industries that benefit from commercial drain jetting
We provide drain jetting services to domestic and commercial clients across every sector. Each industry brings different drainage issues, and our engineers understand what to look for in each setting.
Restaurants, pubs, and hospitality
Kitchen drainage systems take the heaviest punishment.
Fat and grease accumulation, food waste, and high-volume usage mean these drains need jetting more frequently than any other commercial property type. We work around your service hours to avoid disruption, with early morning and late-night visits available.
Regular jetting also helps you stay compliant with Environmental Health requirements for waste disposal and helps avoid the kind of drainage failure that forces a kitchen to close. Where interceptors are fitted, we jet the connecting pipework to prevent buildup between trap services.
Hotels and leisure
Guest rooms, conference facilities, pools, spa areas, kitchens, and bars all feed into the same drainage network.
High occupancy means constant usage across dozens of discharge points. When a hotel drain fails, guests notice immediately.
Scheduled jetting as part of a planned maintenance programme prevents those failures before they affect your guests or your online reviews.
Offices and business parks
Multi-tenant buildings with shared drainage systems are particularly vulnerable to problems, because no single tenant takes responsibility for maintenance until something goes wrong.
We work with facilities managers and property management companies to set up scheduled jetting that covers the whole building, with clear reporting so you know exactly what condition your drainage is in.
Retail and shopping centres
Food courts, toilet facilities serving thousands of visitors per day, and shared drainage infrastructure connecting multiple units.
Retail properties need their drainage maintained proactively because a blockage during trading hours means lost footfall and potential damage to stock in ground-floor units.
Industrial and manufacturing
Factories, warehouses, and processing plants often have large-diameter drainage systems carrying process waste, surface water from hardstanding areas, and effluent that needs to meet trade discharge consents.
Our truck-mounted jetting units handle pipes up to one metre in diameter, and we also jet culverts, gullies, and surface water systems across factory yards and industrial sites. We understand the compliance requirements around trade effluent management and can coordinate sewer cleaning across your entire site.
Healthcare and education
Hospitals, care homes, schools, and universities can’t afford drainage disruption.
Hygiene standards are strict, vulnerable people depend on the facilities, and any closure has a direct impact on the people who use them.
We schedule jetting visits during quiet periods, provide full documentation for your compliance records, and respond quickly if an emergency arises between planned visits.
Planned jetting vs emergency call-outs
You have two choices when it comes to commercial drainage.
You can wait for things to go wrong and deal with the consequences, or you can invest in a maintenance programme that prevents drainage problems from developing in the first place.
Emergency call-outs happen at the worst possible time. Friday evening. Bank holiday weekend. The middle of a busy lunch service. And because the problem has already escalated, the fix takes longer and costs more than a routine maintenance visit would have.
Planned drain jetting works on a schedule tailored to your property.
We assess your drainage system, identify the sections most prone to buildup, and set a jetting frequency that keeps everything flowing.
For most commercial properties, that means quarterly or six-monthly visits. High-risk sites like restaurant kitchens might need monthly attention, while an office building with lower drainage demand might only need an annual jet.
Our planned maintenance contracts include scheduled jetting visits, CCTV condition monitoring, written reports after every visit, and priority emergency response if something unexpected happens between visits. You get a single annual cost that you can budget for, instead of unpredictable emergency bills throughout the year.
Drain jetting vs other cleaning methods
Jetting isn’t the only way to clear blockages in a drain, but for commercial properties it’s almost always the most effective option. Here’s how the benefits of jetting compare to other drain cleaning methods.
Drain rods
Drain rods push through a blockage to restore flow, but they don’t clean the pipe walls. The material that caused the blockage stays in place, and the problem returns within weeks or months.
Rods also can’t reach the distances that commercial drainage systems require, and they struggle with hardened deposits like grease or scale. Jetting is more thorough and lasts significantly longer.
Chemical drain cleaners
Chemical treatments can dissolve some types of blockage in small domestic pipes, but harsh chemicals aren’t strong enough for commercial-grade problems. They also damage older pipe materials and surrounding structures over time, cause environmental contamination when discharged into the sewer network, and pose health and safety risks for the people handling them.
Jetting uses pressurised water only, which makes it environmentally friendly and safer for your pipes, your staff, and the sewer system.
Electro-mechanical cleaning
Mechanical augers and cutting heads work well for specific blockage types, particularly heavy root ingress.
We use electro-mechanical equipment where it’s the right tool for the job, but for general commercial drain cleaning and maintenance, jetting delivers a more complete clean across the full length of the drainage run.
How often should commercial drains be jetted?
It depends on your property type, usage levels, and what’s going into the drains. Here’s a general guide based on what we see across our commercial client base.
- Restaurants, pubs, and commercial kitchens: every one to three months
- Hotels and leisure facilities: every three to six months
- Retail and shopping centres: every six months
- Offices and business parks: every six to twelve months
- Industrial and manufacturing: every three to twelve months, depending on process waste
- Healthcare and education: every six to twelve months
These are starting points.
After your first jetting visit, our engineer will assess how much buildup has accumulated and recommend a frequency that matches your actual usage.
If we find your drains are cleaner than expected at the next visit, we’ll suggest extending the interval rather than billing you for work you don’t need.

Frequently asked questions
How much does commercial drain jetting cost?
The cost depends on the size of your drainage system, the severity of the blockage, and whether pre-jetting CCTV is needed. We provide free, no-obligation quotes before any work begins, so you know exactly what you’re paying. For planned maintenance contracts, we offer discounted rates based on visit frequency.
Will drain jetting damage my pipes?
Not when it’s done properly. Our engineers adjust the high pressure water to suit the pipe material and condition. We run a CCTV check first whenever possible, specifically to identify any structural weaknesses that could be affected. Jetting is actually gentler on pipes than chemical cleaners, because it uses water rather than corrosive substances, with no risk of damage to surrounding structures.
How long does commercial drain jetting take?
A straightforward blockage clearance on a single drainage run takes between one and two hours. A full maintenance jet of a commercial property’s drainage network takes half a day to a full day, depending on the size and complexity of the system. We’ll give you a time estimate when we quote.
Can you jet drains while my business is open?
Yes. The process is non-invasive, and most of our work happens from external access points like manholes and inspection chambers, so there’s minimal disruption inside your building. We routinely jet restaurant drains during service breaks, hotel drains during low-occupancy periods, and office drains during evenings and weekends. We work around your schedule.
Is drain jetting environmentally friendly?
Jetting uses pressurised water and nothing else. No harsh chemicals, no solvents, no substances that could cause contamination in the sewer network or the environment. The water we use is recirculated through our jet vac units, which reduces waste and makes the process environmentally friendly. For businesses with environmental compliance obligations, this matters. Our tanker units can also dispose of waste water responsibly when required.
