Cafes, shops and offices put heavy loads on their drains because many people use them. Kitchens add grease and food waste, so their waste lines clog faster. Jetting clears grease and silt from long pipe runs. A clean line cuts the risk of a block at a busy time.
The engineer finds the access points and the pipe runs. Food sites need extra care around grease traps, since fat builds up quickly there. Tell the engineer about any past blocks.
The nozzle and pressure suit the pipe and the deposits, since each pipe takes a different load. Ask about this before the work starts. A camera look can help to pick the setting.
The jet works from the far end back towards the main drain. Meanwhile, kitchen lines get extra passes for grease. Ask the engineer how they will protect stock and equipment.
Ask the engineer how often your site needs cleaning. A regular visit often costs less than an emergency block. Ask for a short note of the date and the work.
Commercial jetting is priced job by job, so ask for a written quote. Home jetting guides give £70 to £175 (MyJobQuote) and an average of £259 for external drains (HomeServe), but a large site costs more. Ask for a written quote that names the pipe runs, the access and the timing. Ask whether there is a call-out charge.
It depends on what goes down the drain. Kitchens that handle a lot of fat need more regular visits than offices. Ask the engineer to set a plan after a first look. Check the plan again if blocks return.
Often, yes, since early mornings, evenings and quiet days suit many sites. Say what time suits you when you send the request. The engineer who takes the job confirms what is possible.
Yes. A dated note of what the engineer did helps if a landlord, insurer or inspector asks. Ask the engineer for a written note of the date and the work. Keep it with your other site records.
Fat and oil cool in the pipe and stick to the walls. Food scraps then catch on the sticky layer and build into a plug. A grease trap helps, yet it needs regular emptying. Staff should scrape plates into a bin, not into the sink.
It depends on the lease. Check the lease before you book, and ask the landlord or agent if you are unsure. Keep the quote and any footage, since both help if a dispute comes up.
