FAQs
Why is regular grease-trap maintenance and periodic overhaul so important for Cookeville businesses?
A properly functioning grease trap keeps fats, oils and grease (FOG) out of Cookeville’s sanitary sewer system, preventing blockages, backups, odors and fines. Over time solids build up on baffles and walls even with routine pump-outs, reducing capacity and flow. An overhaul resets the trap to “like-new” condition, extends its life, protects your plumbing and ensures compliance with local FOG discharge regulations.
What signs indicate my commercial grease trap needs a full overhaul instead of another routine cleaning?
Warning signs include chronic drain or line backups, foul odors returning soon after pumping, visible corrosion or broken baffles, grease levels reaching the 25 % rule quickly, and inspectors noting excessive solids. If you find yourself scheduling pump-outs more than once a month or the trap has not been dismantled and power-cleaned in 3–5 years, an overhaul is usually the cost-effective solution.
What does your Cookeville grease-trap overhaul service include?
Our licensed commercial plumbers isolate the trap, pump and legally haul away all contents, unbolt covers, remove baffles, scrape and pressure-wash interior walls, hydro-jet inlet/outlet lines, replace worn gaskets, seals and hardware, install new baffles if needed, perform a leak and flow test, deodorize and document the service for city inspectors. All waste is manifested and disposed of at an approved Cookeville facility.
How long will the overhaul take and will my kitchen have to shut down?
Most medium-size (500–1,000 gal) traps can be overhauled in 2–4 hours. We schedule during your slow periods (early morning, late night or weekends) so only the dish area is offline while we work. Full kitchen shutdown is rarely necessary; sinks can resume use as soon as we pass the flow test and reinstall covers.
Are there specific Cookeville or Tennessee regulations I should know about?
Yes. The City of Cookeville Water Quality Control Department enforces a FOG Ordinance requiring commercial food facilities to install and properly maintain grease traps, follow the 25 % rule, keep pump-out/overhaul records for three years and allow inspections. Failure to comply can lead to surcharges or civil penalties. Our service meets all state and local requirements and we provide the paperwork you need for inspectors.
How much does a grease-trap overhaul cost and what affects the price?
Most Cookeville overhauls range from $1,200–$3,000. Pricing depends on trap size and accessibility, severity of buildup, need for replacement parts, after-hours scheduling and waste disposal volume. We provide a free on-site inspection and flat upfront quote, so there are no surprises.
