Great chefs can’t fix broken plumbing.
It seems like stating the obvious. But it’s these kinds of lessons that restaurant owners learn the hard way. By failing an inspection, experiencing an unplanned closure, or dealing with a backed-up drain when it’s the busiest shift of the night.
The truth is…
Commercial plumbing maintenance is the low hanging fruit of restaurant operations. Something every foodservice business thinks they’ll get around to — until they don’t. And when they don’t, the impacts are felt immediately. A properly maintained plumbing system is invisible to your customers. So when things start going wrong, everyone notices.
Let’s take a look at:
- Why plumbing system maintenance should be priority #1
- Consequences of letting it slide
- 3 Levels of plumbing maintenance your restaurant should have on rotation
- How often should you schedule plumbing maintenance?
Why Plumbing System Maintenance Should Be Priority #1
You can’t prepare a great meal without great ingredients.
The basics start with clean water coming out of the tap. Properly functioning drains. And a well-maintained grease trap. Hot water on demand for washing dishes, sanitising food prep stations, and cleaning hands. Without these essentials — something that a functioning plumbing system provides — your entire kitchen will struggle.
Commercial kitchens are hard on plumbing systems. Residential systems simply aren’t built to withstand endless cycles of washing, cooking, prepping, dishwashing, and cleaning. Partnering with experts like Boris Mechanical to keep your plumbing system maintained means taking care of any minor issues before they become costly disasters. Not to mention, before they interrupt your operations.
Customer trust is on the line, too.
Did you know 70% of restaurant patrons will refuse to eat at an establishment that failed a health inspection? Plumbing failures don’t just disrupt your business for a shift. They can turn your carefully cultivated customer base against you overnight.
Consequences of Letting Your Plumbing System Slide
Here’s what happens when you ignore maintenance.
Typically small issues that affect your plumbing system will warn you they’re there. Strange odours. A slow drain. That odd feeling of pressure when you turn on the faucet. But left alone, they’ll become bigger problems. And they’ll let you know it by either flooding your kitchen or forcing you to close up shop entirely.
These are the most common ways poor plumbing catches up with you:
- Stoppage and backups: Grease, food particles, and debris have a way of building up in drains. Over time they create clogs that can stop your kitchen operations dead in their tracks.
- Grease trap overflowing: If your grease trap isn’t cleaned regularly things will back up. Fats and oils are pushed back through your plumbing system when your grease trap reaches capacity.
- Leaks: Faulty pipe fittings, loose connections, or damaged pipes can lead to water damage, mould, and a steep increase to your water bill. Minor leaks can go for long periods without being discovered.
- Fail health inspections: Plumbing problems that cause sewage backups and water damage are considered “closure violations” by most health departments. It’s an automatic fail on inspections.
Need something more concrete?
Just know that being forced to shut down while you wait for a plumber will lose you more money than you think. Between revenue lost and repairs, it can take weeks to recover from a serious plumbing issue. And that doesn’t even account for how your customers will perceive your brand moving forward.
Your best bet? Don’t let it get to that point.
The 3 Levels of Restaurant Plumbing Maintenance
Think of preventative maintenance as tackling one hurdle at a time.
Breaking up your commercial plumbing maintenance into 3 tiers will keep things simple. Daily and shift-based tasks can be handled by your kitchen staff, but weekly and monthly chores should include a certified plumber.
Tasks for Daily and End of Shift Maintenance
Blocking is your first line of defence.
These few tasks should be completed every shift to prevent clogs and keep plumbing basics maintained:
- Remove visible debris from drain screens after every shift
- Never rinse grease or food debris down sink drains
- Wipe down faucet heads and look for signs of leaks
- Garbage disposals are not an appropriate replacement for trash cans
Weekly Tasks
Build healthy habits.
Unless your plumbing system is abused daily (and it probably is), weekly maintenance should be able to fill in the gaps.
- Look for leaks or drips under faucets
- Check sink drains and floor drain outlets for clogs
- Flush drains to keep pipes clear of buildup
- Check water pressure and flow throughout kitchen and bathrooms
Monthly Tasks + Professional Inspections
Schedule monthly drop-ins with a licensed plumber to handle:
- Clean grease traps — depending on your kitchen’s output, you may need this done weekly
- Flush water heater tank to keep your system running efficiently
- Inspect backflow prevention devices
- Check pipe fittings for corrosion and wear
- Replace water filters
Did you know your grease trap is federally regulated?
Minimizing the amount of FOG (fats, oils, grease) that gets poured down kitchen drains is vital. When they go untouched, these oils cool and stick to the interior of your drains — causing stoppages and damaging pipes. Regular grease trap cleaning isn’t optional, it’s required by law.
How Often Should Restaurants Maintain Their Plumbing System?
Hint: it’s more frequent than you think.
This will change from restaurant to restaurant. A commercial kitchen that churns through high volumes of food each day will require more frequent plumbing system cleaning and maintenance than your average café.
However, there is one maintenance task that should always be performed quarterly (every 3 months) by experienced professionals.
Think of it this way. Scheduled maintenance through a qualified technician typically runs kitchens between $100–$250 per month. That’s it. Compare that to the tens of thousands of dollars in lost revenue when your kitchen is forced to close indefinitely.
Preventative maintenance is simple if you have a plan.
- Quarterly professional plumbing maintenance keeps minor issues from becoming major expenses.
- Monthly grease trap service prevents the number one cause of drain stoppages in restaurants.
- Daily and weekly tasks fill in the gaps between professional plumbing inspections.
Partner with a licensed plumber and get on a routine maintenance schedule. That way, when your plumbing does act up you can call your friendly neighbourhood technician instead of an emergency line. And in reality, there’s nothing quite like dining at a restaurant that doesn’t have to resort to emergency services to keep their kitchen in working order.
Final Thoughts on Preventative Plumbing Maintenance
Great chefs deserve great kitchens.
Routine plumbing maintenance isn’t glamorous. Customers won’t rave about it on Yelp. But that doesn’t mean it isn’t important — every aspect of your operation depends on running toilets, functional dishwashers, and hot water on demand. From opening your doors in the morning to sanitising your dishes at night.
Don’t leave it up to chance.
Get on a maintenance schedule, build relationships with certified plumbers, and treat your plumbing system with the same care you would any other aspect of your business. Because even the greatest chefs in the world can’t cook a meal without clean water.
