Commercial jetting cleans the drains of shops, cafes, restaurants, offices, and warehouses. These drains carry more water than a home, so deposits build up faster. Grease and fat are the main problem in food kitchens. Since larger pipes need stronger equipment, ask what unit the engineer will bring.
The engineer walks the site to find access points, pipe runs, and trouble spots. In a food business, grease traps and kitchen waste lines need extra care. Since each site differs, this walk-round shapes the plan.
The unit, nozzles, and pressure depend on the pipe material and the type of deposit. For example, a grease-cutting nozzle suits kitchen lines. Larger pipes need stronger equipment, because they carry more water.
The engineer jets each pipe section, from the far end back towards the sewer connection. Kitchen lines get extra passes because grease sticks to the pipe walls. As a result, the whole run ends up clean.
Ask for a written record of the work, with the date and scope. If you want regular visits, agree a schedule that suits your business. Since inspectors may ask for proof, keep the record safe.
The cost of commercial jetting depends on the size of the drain system and how heavy the deposits are. Ask whether a regular schedule lowers the price per visit. Because every site differs, ask for a written quote after a site check. Also ask whether there is a call-out charge.
It depends on the business. Kitchens that make a lot of grease need cleaning more often than offices. Since every site differs, ask the engineer to suggest a schedule after they see the drains.
Ask the engineer to plan around your opening hours. Early mornings, evenings, and weekends are common choices for food businesses. Because your staff need notice, agree the time before work starts.
Some businesses do. Yorkshire Water sets the rules on trade effluent, so check with them before you discharge anything other than normal sewage. Regular drain cleaning also helps, because it keeps grease out of the sewer.
