How Often Should You Clean Your Grease Trap? A Guide for Montana Restaurants
If you own or manage a commercial kitchen in Billings, Laurel, or anywhere in south-central Montana, your grease trap is one of the most important parts of your plumbing system. Neglecting it? That’s a recipe for clogs, foul odors, health code violations, and emergency plumbing calls. At Andersen Sewer Service, we specialize in commercial grease trap pumping and help Montana restaurants stay clean, compliant, and open for business. Let’s break down how often you should clean your grease trap — and why it matters.
What Is a Grease Trap and Why Is It Important?
A grease trap separates fats, oils, and grease (FOG) from wastewater before it enters your plumbing system. Over time, that trap fills up — and if it’s not cleaned out regularly, it backs up into your kitchen. Cities like Billings and Lockwood enforce strict regulations on how often businesses must clean their traps. Some even require service logs for inspections.
General Guidelines for Grease Trap Cleaning
While frequency depends on your volume, here are some general rules:
– Every 1 to 3 months for most restaurants
– Monthly for high-volume kitchens or those cooking with heavy oils
– More frequently if required by local health departments
If you’re in Laurel, Columbus, or Hardin, be sure to check with your local inspector — or let Matt at Andersen Sewer Service help you set a smart schedule.
Warning Signs Your Trap Is Overdue for Cleaning
Not sure if it’s time? Here are red flags:
– Bad smells near sinks or drains
– Grease visible in manholes or floor drains
– Slow-draining sinks
– Past-due compliance logs
– You’ve forgotten the last time it was cleaned
If you’re noticing these in Roundup, Billings, or beyond — it’s time to call us.
