The Bottom Line (Quick Answer for Restaurant Managers): To prevent unexpected plumbing closures in a commercial kitchen, managers must prioritize four regular maintenance tasks: quarterly hydro jetting to clear hardened grease (F.O.G.), annual descaling of commercial water heaters to combat Utah’s hard water, routine inspection of high-traffic restroom fixtures, and enzyme treatments for floor drains. Partnering with a 24/7 local commercial plumber ensures a rapid response in the event of an emergency.
Running a restaurant anywhere is tough. Running one in the Salt Lake Valley adds its own unique flavor of challenges—especially when it comes to your facility’s infrastructure. Between managing staff turnover, balancing food costs, and keeping the front-of-house happy, the absolute last thing you need is a floor drain backing up at 7:00 PM on a Friday.
When a commercial kitchen’s plumbing goes down, the consequences are immediate. You aren’t just dealing with a mess; you’re facing halted operations, potential health department violations, a reputational hit, and thousands of dollars in lost revenue.
For restaurants operating along the Wasatch Front, hoping for the best isn’t a strategy. Proactive plumbing maintenance is. Here is exactly what you need to keep an eye on to keep your doors open and your kitchen moving.
In the restaurant industry, Fats, Oils, and Grease—commonly known as F.O.G.—are public enemy number one. Even if your kitchen staff is incredibly disciplined about scraping plates, grease will inevitably find its way down your drains.
Once hot grease hits the cooler pipes under your foundation, it congeals. Over time, it turns into a rock-solid blockage that narrows the pipe and eventually causes a massive, foul-smelling backup. Pumping your grease trap is legally required, but it doesn’t clean the sewer lines that lead away from your building.
The Fix: You need routine hydro jetting. Snaking a drain pokes a hole through the grease. Hydro jetting uses specialized, high-pressure water streams to actually scour the interior walls of your pipes, slicing through hardened grease and flushing it entirely out of your system. Getting your main lines hydro-jetted on a quarterly or biannual schedule is one of the smartest investments a restaurant owner can make.
If you live in Utah, you already know our water is notoriously hard. But in a commercial kitchen, the calcium and magnesium in our municipal water supply do a lot more than leave water spots on wine glasses.
To meet local health codes, your commercial dishwashers and high-capacity water heaters must meet strict temperature requirements (typically 150°F for washing and 180°F for rinsing). Hard water causes scale to build up rapidly inside these heating elements. This scale acts as an insulator, forcing your equipment to work twice as hard to heat the water. Eventually, the units fail. And if you lose your hot water supply, the health department requires you to shut down immediately.
The Fix: Your commercial water heaters and boilers need to be professionally flushed and descaled at least once a year. If you are constantly replacing elements, installing a commercial-grade water softener or filtration system will protect your expensive kitchen equipment and keep you compliant.
Customers absolutely judge the cleanliness of your kitchen by the state of your restrooms. A clogged, overflowing, or out-of-order toilet during a dinner rush is a guaranteed way to earn a one-star review.
Commercial restrooms take a beating. They handle hundreds of flushes a day, and let’s face it, customers flush things they shouldn’t—from excessive paper towels to sanitary products. The internal mechanisms of commercial flushometers wear out much faster than those of residential toilets.
The Fix: Don’t wait for a toilet to overflow into the hallway. Have a local plumber conduct routine walkthroughs to check flush valves, test sensors, and proactively auger the main restroom drain lines to catch partial blockages before they become total failures.
Floor drains handle everything from mop bucket water to accidental spills. But when they are neglected, they become a massive liability.
If a floor drain trap dries out, or if organic matter builds up inside the grate, you’ll get two things: a terrible sewer gas smell creeping into your dining room, and an infestation of drain flies. Neither of those is going to whet your customers’ appetites.
The Fix: Train your closing staff to use biological and enzymatic cleaners to maintain floor drains properly. Bleach doesn’t cut it—it just flows right past the sludge. Enzymatic cleaners actually eat the organic matter. During a maintenance visit, a plumber will ensure your traps are holding water correctly and that your venting system is pushing sewer gases out the roof, not into the kitchen.
The absolute worst time to look for a commercial plumber is when you are standing in ankle-deep water while tickets are printing in the kitchen.
Establishing a relationship with a local plumbing partner means you have a crew on speed dial who already knows your building’s layout, where your cleanouts are, and the specifics of your equipment.
If you manage a restaurant in Midvale, Sandy, West Jordan, or anywhere in the greater Salt Lake Valley, get ahead of the problem. Check out our Commercial Sewer & Drain Services and let’s set up a preventative maintenance plan that fits your business. Plumbing Utah is open 24 hours a day for emergencies—because we know the restaurant industry never sleeps.
How often should a restaurant have its pipes hydro-jetted? For high-volume restaurants, fast-food locations, or kitchens that do a lot of frying, quarterly hydrojetting is recommended. For smaller cafes or low-grease operations, bi-annual or annual jetting is usually sufficient to prevent backups.
What happens if my restaurant loses hot water in Utah? According to local health department regulations, restaurants must have adequate hot water for handwashing and sanitizing dishes. If your commercial water heater fails and you lose hot water, you must close the facility until the hot water supply is restored.
Can I use chemical drain cleaners to clear a kitchen clog? No. Chemical drain cleaners are highly corrosive and can eat through your commercial pipes, leading to costly repiping. They are also dangerous for your kitchen staff to work around. Professional snaking or hydro jetting is the only safe and permanent way to clear a commercial clog.
