FAQs
How often should a commercial grease trap in Maryville be cleaned?
For most restaurants and food-service facilities in Maryville, the City’s FOG (Fats, Oils & Grease) ordinance and Tennessee plumbing codes recommend cleaning every 90 days or when the trap is 25 % full—whichever comes first. High-volume kitchens, cafeterias, or establishments that fry or bake continuously may require monthly or even bi-weekly service. Our technicians measure the grease layer during each visit and advise the exact schedule to stay compliant and prevent backups.
What does your grease-trap cleaning service include?
Our comprehensive service includes: 1) pumping out the entire contents of the grease trap or interceptor, 2) scraping and power-washing the walls, baffles, and cover to remove hardened waste, 3) inspecting inlet/outlet tees and gaskets for damage, 4) disposing of all waste at a state-licensed FOG processing facility, and 5) providing a detailed manifest and service report for your health-department records. We also offer enzyme dosing and flow-rate checks upon request.
Will grease-trap cleaning disrupt my business operations?
We schedule service during off-peak hours—early mornings, late nights, or weekends—to minimize interruption. A standard in-kitchen grease trap (20–50 gal) takes about 30–45 minutes, while an outdoor interceptor (500–1,500 gal) can take 1–2 hours. Our vacuum trucks are equipped with extra-long hoses to keep doors closed and odors contained, so your staff and customers experience minimal disturbance.
What are the signs that my grease trap needs immediate attention?
Common red flags include slow-draining sinks, foul odors near floor drains, gurgling sounds, grease slicks in parking-lot clean-outs, or a sudden visit from the City of Maryville Pretreatment Inspector. If you notice any of these, call us for expedited service. Ignoring them can lead to line blockages, expensive plumbing repairs, or fines for sewer overflows.
Do you provide documentation for health and environmental compliance?
Yes. After every cleaning we issue a digital and hard-copy manifest showing date, time, volume pumped, disposal site, and technician certification number. This meets Maryville Water & Sewer Department, Blount County Health Department, and EPA requirements. We also maintain electronic records for five years in case of audits or permit renewals.
What affects the cost of grease-trap cleaning in Maryville?
Pricing depends on trap/interceptor size, grease volume, ease of access, service frequency, and whether after-hours labor is required. Small indoor traps start around $185 per visit, while large outdoor units range from $0.22–$0.28 per gallon pumped. We offer volume discounts for multi-location franchises and no-surprise annual contracts that lock in rates and include 24/7 emergency response.
