Questions to Ask Your Contractor Before Grease Trap Installation Begins
CITI INDUSTRIES 
Installing a grease trap is one of those critical investments that can save your restaurant or commercial kitchen from expensive plumbing nightmares down the road. But here's the thing: not all contractors are created equal, and the wrong installation can lead to compliance issues, frequent maintenance headaches, and unexpected costs that drain your budget.
Before you sign any contract or hand over a deposit, arm yourself with the right questions. A knowledgeable contractor won't just tolerate your inquiries—they'll welcome them. Here are the essential questions that will help you separate the professionals from the pretenders.
Licensing and Experience
Start with the basics: "Are you licensed and insured for grease trap installation in this area?" This isn't just a formality. Grease trap work often requires specific plumbing licenses, and insurance protects you if something goes wrong during installation. Follow up by asking how many grease trap installations they've completed in the past year. Experience matters, especially when dealing with older buildings or complex plumbing systems.
Sizing and Compliance
One of the most common mistakes is installing a grease trap that's too small for your operation. Ask your contractor: "How did you calculate the required size for my grease trap?" They should be able to explain their methodology based on your kitchen's fixture units, flow rate, and local regulations. Don't accept vague answers here.
Additionally, inquire: "Will this installation meet current local health department and plumbing codes?" Your contractor should be intimately familiar with your municipality's requirements and be willing to handle the permit process.
Installation Details
Get specific about the work itself. Ask about the timeline: "How long will the installation take, and will my kitchen need to shut down?" Most businesses can't afford unexpected downtime, so you need clarity on whether you'll be able to operate during installation.
Question the placement too: "Why are you recommending this location for the grease trap?" The ideal spot balances accessibility for maintenance with practical plumbing considerations. Your contractor should explain their reasoning in terms you can understand.
Maintenance and Long-Term Costs
Here's a question many people forget: "What kind of ongoing maintenance will this system require?" Different grease trap systems have varying maintenance needs. Understanding this upfront helps you budget for the true cost of ownership, not just the installation price.
Also ask: "What warranty do you provide on both parts and labor?" A reputable contractor stands behind their work with a solid warranty that covers potential installation defects.
Red Flags to Watch For
If your contractor can't provide clear answers, rushes you to sign, or suggests cutting corners to save money, walk away. A quality installation might cost more upfront, but it pays for itself by preventing violations, backups, and premature replacement.
The bottom line? Your grease trap installation is too important to leave to chance. These questions will help you find a contractor who views your project as more than just another job—someone who'll deliver an installation that keeps your kitchen running smoothly for years to come.
