How Do You Know When a Grease Trap Needs Pumping?
You measure it, not guess. The 25 percent rule is the industry benchmark for fats, oils, grease and solids buildup, and that is what triggers a pump-out, not the calendar. A restaurant running a fryer and a dish pit in Plymouth can hit that mark faster than a small cafe, so Plymouth Porta Pros checks depth on-site instead of applying one interval to every kitchen. Skip a cycle and grease backs into floor drains, slows your line, and eventually violates the discharge terms in your commercial sewer agreement. We pair this with our septic pumping service for properties running both a grease interceptor and a septic tank, and with septic tank cleaning when solids build up alongside the grease layer. If you are not sure which one you have, our septic tank warning signs page walks through the difference. Most residential septic tanks only need attention every 3 to 5 years, a much longer interval than a working kitchen's grease trap, so do not manage the two on the same schedule.
What Does Grease Trap Pumping Cost in Plymouth?
Cost depends on trap size, grease depth, and how far our truck has to travel to reach you.
| service | duration | low | typical | high |
|---|---|---|---|---|
| septic/grease pump-out | day | $150 | $250 | $300 |
| septic/grease pump-out | weekend | $50 | $100 | $150 |
| service call fee | day | $100 | $175 | $300 |
A weekend call for a Plymouth restaurant that cannot shut the kitchen midweek runs toward the lower end of that weekend band, since it is a shorter visit than a full day service. For a broader breakdown by tank type, see septic tank pumping cost. Commercial accounts with recurring pickups pay less per visit than one-off emergency calls, similar to how monthly porta potty rental beats a single day rate on our sanitation side. If your kitchen is part of a larger build-out, pair this with construction site services and a roll-off dumpster rental for demo debris.
Do You Offer Emergency Grease Trap Pumping in Plymouth?
Yes. A backed-up interceptor does not wait for a Monday appointment, and neither do we. Plymouth Porta Pros runs emergency grease trap pumping for kitchens in Plymouth and nearby, including Minnetonka 7.2 miles south, St. Louis Park 9.1 miles southeast, and Eden Prairie 12.8 miles south. Standing grease near a service entrance is also a slip hazard under ADA Standards 302.1's requirement that floor surfaces stay stable, firm and slip resistant, which matters if your back-of-house route connects to a public path. We also run emergency septic service for tanks that fail after hours, and handwashing station rental or a portable sink rental when a kitchen needs backup handwashing per 29 CFR 1910.141(d)(2) while the main line is down. For active job sites nearby, see our coverage from Brooklyn Center to Edina.
How often should a commercial kitchen schedule grease trap pumping?
Most Plymouth kitchens land between every 4 and 12 weeks, set by grease volume rather than a fixed date. High-fryer kitchens need shorter intervals. We check the 25 percent depth mark at each visit and adjust the schedule instead of guessing.
What size grease trap do I need?
Trap size depends on kitchen output, plumbing code, and meal volume, and that is a conversation with your plumber or the city, not a fixed number we assign. We pump whatever size interceptor is already installed.
Can you pump a grease trap and a septic tank on the same visit?
Yes, if both are on the property. See septic pumping service for tank details and holding tank rental if you need temporary capacity during a renovation.
Is grease trap pumping different from septic pumping?
Yes. A grease trap catches fats, oils and grease before they reach the sewer line, while a septic tank handles all wastewater. Check septic tank warning signs if you are unsure which system is failing.
Do you serve areas outside Plymouth?
Yes, including Minnetonka, St. Louis Park, Brooklyn Center, Eden Prairie and Edina. See Service Areas or request a quote for your address.
