Blocked drains can spell big trouble for any commercial kitchen. A backed-up drain can shut down operations, damage equipment, and cause costly water damage if not addressed promptly. However, staying on top of potential drain clogs is essential to smooth kitchen management.
Commercial kitchen drains have to work extra hard compared to typical household pipes. They constantly contend with heavy flows of hot water, grease, food solids, and other materials. While cleaning and proper trash disposal help, eventually, most drains will experience a blockage. Knowing how to identify and remedy common clogged drain problems quickly is crucial.
This blog will cover the main causes of blocked drains in commercial kitchen environments. We’ll look at signs your drain may be plugged and the first steps to take. We’ll also provide advice on clearing minor clogs yourself versus calling a professional.
Common Causes of Blocked Drains in Commercial Kitchens
Several issues routinely cause drain blockages in commercial kitchen settings. Knowing the primary drivers can help catch problems earlier and prevent future backups. The top causes of blocked drains in restaurants and food service facilities include:
Grease Buildup
Commercial kitchen equipment like grills, fryers, stoves and dishwashers generate large volumes of hot, greasy water that flow through drains daily. Over time, this grease can congeal and stick to drain walls, forming clogged pipes. Warm grease cools and hardens quickly in pipes.
Food Debris
Small food particles can still enter drains even with proper scraping and dishwashing. Rice, flour, eggshells, oily residue and other solid food scraps get trapped in bends and catch grease buildup.
Pipe Mineral Deposits
Some areas have hard water that leaves mineral deposits inside drain lines. Over the months and years, these calcium and limescale concretions can reduce pipe diameters.
Clogged Grease Traps
External grease traps are a required part of most kitchen plumbing systems. However, they need regular cleaning to prevent the entire trap from filling with solids, restricting drainage. Neglected traps exacerbate other clogged drain issues.
Signs Your Commercial Kitchen Drain May Be Blocked
Commercial kitchens can take several proactive steps to prevent clogged drains and backups from occurring in the first place. One of the most important is implementing a thorough cleaning routine.
Food debris must be scraped from a blocked sink, floor drains, and equipment before washing, and hot, soapy water is ideal for breaking up residual grease. Avoid pouring fats, oily residue, and grease (FOG) down the drain, as these quickly congeal and accumulate in pipes.
Absorbents like drain mats and screens also capture particles before they enter the plumbing system. Regularly scheduled drain maintenance, such as inspections, treatments, and grease trap pumping performed by a professional plumber, can catch problems very early.
Kitchen staff should also receive training on proper garbage disposal and best practices, such as using a commercial sink strainer in blocked sink drains. Following relevant health codes is also pivotal for reducing risks.
Leaks in sewage discharge on your property cause excessive water bills. Adopting preventative habits saves time and money in the long run compared to costly repairs from severe clogs and backups disrupting business. Proper FOG management and maintenance are key for keeping commercial kitchen drains flowing optimally.
How to Fix Blocked Drains in Commercial Kitchens
Depending on the severity of the clog, there are several different approaches to clearing commercial blocked drains. For minor clogs indicated by slow drainage, you can often try a chemical drain cleaner. Carefully pour baking soda or vinegar into the drain and let it sit for 30 minutes before flushing with hot water. This can dissolve light grease buildup or food residue.
To correctly use a plunger, place the cup over the entire drain opening and cover the lipped rim with water. Push the plunger up and down to create suction and push the clog down the drain. You can also use a drain snake - a pipe with a flexible wire coil on the end that is manually cranked through the drain to break up clogs.
However, if clearing attempts don’t improve flow, it’s time to call a plumber. Professional drain cleaners use high-power water jets, advanced snake tools, and camera inspections to fully unclog sinks and pipes. They can also chemically treat commercial drains or mechanically remove built-up grease rings that minor methods can’t handle.
To fully fix the underlying issue, your plumber may advise installing or drain cleaning your external grease trap if neglected. Don’t attempt to work on grease traps yourself for safety and to avoid code violations. With plumber assistance and prevention measures, you can get your drains cleared and keep them flowing well into the future.
