City Grease Interceptor Codes and Contact Info

City water regulations and codes are complicated. Here’s how to find answers faster in your city’s code:

1. Trapzilla units are hydromechanical grease interceptors. If you see the words “hydromechanical grease interceptors,” chances are good Trapzilla is allowed. The same goes for “AGRU” or “automatic grease removal units,” which is what our units are.

2. Look for any references to ASME and PDI certifications. Trapzilla units are certified by both.

3. If your city’s code requires all grease interceptors to have a long retention or detention time (anywhere from 30 minutes to 12 hours), your city may only approve grease interceptors larger than Trapzilla. Most cities offer a variance if you don’t have much space and don’t produce much grease. Ask your plan reviewer for a variance to use Trapzilla.

4. If local code dictates pumping before grease and solids reach a combined 25% of the liquid volume, it may approve only units larger than Trapzilla. Most cities offer a variance if you don’t have much space and don’t produce much grease. Ask your plan reviewer for a variance to use Trapzilla.
 
 
Grease interceptors are often specified in local plumbing codes. Many city plumbing codes are edited versions of either the Uniform Plumbing Code or International Plumbing Code, altered by a few local amendments.

• A good rule of thumb is referring to UPC Chapter 10.
• Here is the pertinent part of the IPC. 

Regardless, final approvals are often left at the discretion of your local regulator. Click the eyeglass below to search for your city’s grease trap specifications. Questions? Contact us at (800) 633-4204 or info@thermaco.com. Does your city give the okay for Trapzilla?
