The Interceptor Whisperer


Interceptor Whisperer Launches Independent Consulting Service

March 10, 2017 Ken Loucks

A career is a funny thing - rarely can a person predict their career path. People often ask me what I do and how I got where I am in my career. That always makes me smile. I started out working in plumbing wholesale distribution. I went from warehouse man, to truck driver, to inside sales, to outside sales and finally branch management. Then I wanted to move up the industry 'food chain' and the next level up for me was working for a manufacturer's representative. Later I started my own agency, which is when I was introduced to Schier...


Integral vs External Vented Flow Control; How the Code Distinguishes Between Them

January 03, 2017 Ken Loucks

The Uniform Plumbing Code (UPC) provides requirements governing flow control devices for commercial grease interceptors. Confusion and subsequent questions are prolific enough to warrant a blog post to clear things up. Here you go. You're welcome. Here is the verbiage contained in the Code that is confusing, "No flow control device having adjustable or removable parts shall be approved." A few manufacturers of hydromechanical grease interceptors (HGI) use built-in or 'integral' flow controls. The challenge for Code readers is deciding whether the previous language applies to these devices or the exception in the Code, which reads, "Listed grease interceptors with integral flow...


What Exactly is Hydromechanical Separation?

December 05, 2016 Ken Loucks

Did you know that the term hydromechnical or hydro-mechanical if you prefer, is not unique to grease interceptors? For example, Hydro-mechanical drive-trains are a type of transmission used in a variety of different types of vehicles from small passenger hybrids to very large construction equipment.  I decided to look up the definition of hydromechanics, which is a noun that means "hydrodynamics" (seriously), which is a noun meaning, "the branch of fluid dynamics that deals with liquids, including hydrostatics and hydrokinetics." Hydromechanics and hydrodynamics are interchangeable terms that essentially mean the same thing. Hydromechanical is an adjective form of the term...


What is Air Entrainment?

October 18, 2016 Ken Loucks

Once in a while I hear something that makes my mouth fall open while a look of utter astonishment creeps over my face. Since I work from a home office most people would not be able to observe these visible signs of incredulity, but it might look something like: Recently someone claimed that a certain manufacturer's grease interceptors are not hydromechanical grease interceptors (HGIs) because they do not incorporate air entrainment. A statement like that is a little inside baseball so I understand if you don't understand my initial reaction. The definition of a HGI in the International Plumbing Code (IPC)...


Is Lard Still an Appropriate Media for Testing HGIs?

September 14, 2016 Ken Loucks

Why do we still use pork lard for testing and rating hydromechanical grease interceptors? There are so many different oils used in cooking today with varying densities and viscosities; isn’t it time to change from pork lard to something else? These questions come up from time to time and deserve an answer. The issue at question is whether the results of tests that use lard would vary distinctly from the results of tests that use some other test media. There would likely be some difference, to be sure, but the question is whether the difference is statistically significant or not....
