The Striem Lab Rat has been updated

Old Method
We tapped a 2" connection into the tank for each location (three for the LB-2 and four for the LB-5). Then, we threaded in a 1-1/2" adapter on the inlet and outlet, thus giving the contractor the option of using 1-1/2" or 2" connections. We also threaded in a 2" plug on the top of the tank, which is the optional top inlet. Over time, several issues began to surface with this method:
  • Tapping takes a lot of time.
  • Sometimes the threads would not be perfect, so we would scrap the tank.
  • The tapping machine didn't like the amount of torque required to thread polyethylene, causing machine downtime.
All of these reasons had the effect of potentially increasing lead times to our customers, which is no bueno.

New Method

We now spin weld a 2" injection-molded female-thread connection into the tank for each fitting location. We provide the adapters and plug uninstalled in the box. The benefits:
  • The contractor no longer has to remove any adapters if they want to change from a side inlet to a top inlet.
  • The threaded connections are injection-molded quality, making thread engagement very easy in the field. 
  • If the contractor is running 2", they just need to thread on the inlet plug (side or top), then it's ready to go.
  • We can now manufacture the product in a quarter of the time that it used to take.

For that chemistry lab that needs (80) LB-2's, we can now ship the order the next day!
Did You Know?
The bottom of the LB-2 and LB-5 are molded so that a contractor can cut a piece of 4" pipe to use as a "field-adjustable" pedestal. This allows the installer to quickly raise the tank to meet higher inlet inverts while eliminating strain on the sink's tailpiece. ​

What is two-step sizing for a grease interceptor?

What is two-step sizing for grease interceptors is a common question I am asked. Uniform Plumbing Code (UPC) sizes hydromechanical grease interceptors (HGI) by flow rate (pipe size) as shown in step 1 above. If you are using a 4" grease waste line on a project UPC would require a minimum 75 GPM HGI (2-minute drain time) such as the Schier GB3. The GB3 is a third-party certified 75 GPM HGI so code is satisfied, right?

Technically yes, but the shortcoming of stopping at step 1 is that it does not factor loading. Compare two similar restaurants, let's say they are similar in size, kitchen equipment, the number of meals served per day (let's say 300) but the difference is food type. Restaurant 1 is a sandwich shop and restaurant 2 is a bar and grille. Back to the GB3 that satisfied UPC. The GB3 is third-party certified to a maximum grease capacity of 175.6 lbs of grease separated and stored. The sandwich shop would be considered a category A in step 2 above and produce 0.005 lbs of grease per meal served. 300 meals served per day * 0.005 lbs per meal served = 1.5 lbs of grease produced per day. By comparison the bar and grill at 300 meals served per day * 0.0455 lbs per meal served = 13.65 lbs of grease produced per day.

See the problem with stopping at step 1? If the GB3 is used it will require maintenance every 117 days at the sandwich shop (175.6 capacity of GB3 / 1.5 lbs grease produced per day). The bar and grill every 12 days (175.6 / 13.65). Both are UPC compliant per step 1 but by not considering loading they yield two very different maintenance intervals. 

The solution? The Schier GB-250 is 100 GPM, satisfies step 1 as it's 75 GPM or larger but will separate and store 1,751 lbs or grease. By using a GB-250 in the bar and grill application we can match the maintenance interval of the sandwich shop. 1,751 lbs grease capacity / 13.65 lbs produced per day = 128 days between cleanings. 

That's the basic concept of the two step approach. To make this really easy Schier has an online sizing program Grease Monkey that will allow you to input all parameters of the job and give a recommendation. They even have a team that will pre-approve AHJ acceptance and it's free.

New! Schier Safety Manway

The Schier Safety Manway builds on the Safety Star concept that comes standard on the GB-500 and GB-1000 models. An open manway is a safety concern and every year people fall inside and are injured or worse, killed.  The Safety Star was developed to help protect against accidental entry into the grease interceptor. As the photo shows the pumper hose will still fit inside of the openings and the bright yellow Safety Star can hold 400 lbs. It's also removable but comes with a tether to make sure it doesn't go too far. A security screw can also be used to help with tampering. 

The Safety Manway is designed to be a universal fit for any buried tank. Concrete grease interceptors, oil/sand separators, chemical tanks, solids interceptors,  septic tanks, sanitary sewer access points, storm sewer access points just to name a few.

One of the many new features of the new Schier Products GB-500 is the Safety Star™. This game changing bright yellow Safety Star™ lives directly below the access-way covers and helps to prevent accidental entry into the GB-500. The Safety Star™ can be removed for servicing or inspection but is tethered to the adapter to ensure it is always put back in place. The Safety Star™ will be a standard feature on the GB-500 shipping early 2019.

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. More about the GB-500 can be found here >>

Striem describes some of their products as being rotomolded (rotationally molded) but what does that mean? Watch the Ripple Engineering Pressure-Cooled Rotomolding machine in action at Striem in Kansas City in the video above. More about how the machine works can be found at the Ripple Engineering website.

Introducing the GB-1000. That's right, 1,000 gallons of hydromechanical grease interceptor with a third-party performance certification proving it holds 6,547 lbs of grease! Don't take our word for it, have a look at the ASME test report. Why specify a large volume grease interceptor without knowing what it actually holds?  Click here for all the information including technical data package in PDF and DWG as well as Revit and CSI masterspec files.
