With 510 gallons of capacity the GB-500 slots perfectly between the successful 275 gallon GB-250 and the new 1,010 gallon GB-1000. Available early 2019 the GB-500 is third-party certified to ASME A112.14.3-2018 to hold 3,048 lbs of grease. The GB-500 can be installed above or below grade and has a new riser system allowing up to burial depths of 8' (top of unit to grade). A few firsts for the GB-500 is also the new triple inlet and outlet design allowing for ultimate design ease as well as the Safety Star™ feature preventing accidental entry into the tank.

I'm asked often by engineers should a hose bib be placed near an indoor grease interceptor and the answer is yes.  Hot water is preferable but cold will do if thats all that is practical for the design. During the cleaning process the pumper will remove the FOG and solids that have accumulated since the last cleaning and while the tank is empty best practice is to spray down the interior walls and diffusers of any remaining material.

If you specify grease interceptors and aren't familiar with the Interceptor Whisperer, you should be. The blog created by IW Consulting answers many common questions regarding interceptor history, technology and best practices. 

Should a floor drain, floor sink or dishwasher be connected to a grease interceptor? Read about it on the IW blog post: https://www.iwconsultingservice.com/single-post/2017/04/16/Which-Fixtures-Should-Be-Connected-to-a-Grease-Interceptor

One benefit of our units being third-party certified (by NSF to ASME A112.14.3) is we know exactly how much grease our units will hold. The concrete gravity type vault doesn't have this benefit as there is no perfomance testing required and leaves inspectors to apply a general rule as to when the unit is full and in need of being pumped out. Schier's  GPSM (grease production sizing method) allows us to fine-tune the sizing based on food type and pumpout interval. If you had a similar size Subway and BBQ restaurant just counting DFUs and seats would basically size them out as the same size interceptor when they would be creating two completely different amounts of grease.

Well, good news. ASPE has adopted the GPSM into the latest handbook. Using this method reduces unnecessary expenses for your client while allowing you to specify a grease interceptor that will meet their needs and function properly.

This is one of those products that I see and think this really is a problem solver. Zero lot line buildings can be tough for grease interceptors. Concrete units often go into the bottom of the parking garage they are difficult to maintain and when they fail due to corrosion are difficult to replace, lose-lose. Schier Products Great Basin series of grease interceptors are made of HDPE, have a lifetime warranty, can be installed above or below grade, can be installed in series to increase pump-out frequency and now the best part... offer a remote pump-out port option. This kit allows you to install the interceptor inside the building but have a hard pipe connection to a cam lock on the outside of the building allowing the pumper contractor to service the unit without dragging hundreds of feet of hose around the garage. While the unit is being serviced is also creates a negative air situation thereby minimizing the smell around the open unit and allows to pumper contractor to complete the service with minimal impact to the building occupants.
