Commercial Drain Jetting explained
Commercial drains work harder than home drains. Kitchens send grease and food waste into the pipe all day, while shops, offices and washrooms add heavy use, and a block can stop trading. Regular care can cost less than a stopped kitchen.
High-pressure jetting scours the pipe walls along the whole run. It suits grease build-up, silt and scale. Rods can clear a block but may still leave the film behind.
Business premises vary a great deal, although the method is much the same. Read the general guide to drain jetting first. The page on domestic drain jetting and drain cleaning explains the same method at home scale.
Why business drains need regular care
Fat from cooking cools and sets inside the pipe. It then catches food scraps, so the layer thickens with every shift. A block can build up for weeks before it shows.
Regular cleaning can cost less than a stopped kitchen, although the right schedule depends on your menu. Ask the engineer what the pipe walls show on the first visit, since they reveal how fast build-up forms. Keep a simple log of blocks and visits.
How a job usually runs
- 1. Describe the premises
Your request should say what the business does and where the drains run. Kitchens, washrooms and floor drains each have their own pipes. Mention how often blocks happen, since a pattern helps the engineer plan.
- 2. Plan the visit
Ask whether the work can happen outside opening hours. Early mornings, evenings or closed days may suit, although not every engineer offers them. Agree access to manholes and grease traps.
- 3. Jet the runs
Water jets scour the pipe walls while they flush debris to a collection point. Grease traps may need emptying as a separate job. Ask who handles this.
- 4. Keep a record
Ask for a written note of the date, the runs cleaned and any faults seen. A record helps if a landlord, insurer or inspector asks about drain care, since you can then show what was done. Keep it with your other premises papers.
What to ask the engineer
The engineer who takes your job runs a separate business, so the engineer sets the price, the arrival time and any guarantee. Use these questions to compare quotes, since answers differ from one engineer to the next. Write the answers down, because a written note helps if the job changes.
- Is there a call-out charge, and what does it cover?
- Can the work happen outside opening hours?
- Will you give a written record of the visit?
- Does the price cover grease traps, or only the pipes?
- How often do you advise cleaning for a kitchen like mine?
What it can cost
The guides checked for this page include no reliable figure for commercial drain jetting. However, they cover homes, so their figures may not fit a business. Use them only as a loose reference.
For reference, MyJobQuote lists domestic jetting at £70 to £175. Larger systems and out-of-hours work can still cost more. Ask for a written quote that names the runs covered.
Commercial Drain Jetting questions answered
How often should commercial drains be jetted?
It depends on the business. Kitchens that send a lot of grease into the drain may need regular cleaning, while offices with light use need it less. Ask the engineer to suggest a schedule after the first visit.
Can jetting happen outside business hours?
Some engineers can work early, late or on closed days, although not all can. Ask when you send the request, and agree the time in writing. An out-of-hours charge may apply.
Will I get a record of the work?
Ask for one. A written note of the date, the runs cleaned and any faults seen helps if a landlord or insurer asks, since it shows what was done. Not every engineer provides one by default.
Who is responsible for a grease trap?
Check your lease and any rules that apply to your premises. Ask the engineer whether the visit includes the trap, since the answer differs between engineers. Your landlord or local council can advise on local rules.
