This guide summarizes current Schier Great Basin documents without ranking the brand or prescribing a restaurant size. Schier's product line includes base models and alternate configurations whose ratings are not interchangeable. Always use the complete model name and current submittal.
Current Great Basin examples
| Exact configuration | Current published rating | Installation scope stated by Schier |
|---|---|---|
| GB2-C | 35 GPM; 130 lb grease capacity; 20 gal liquid capacity; 52 lb product weight. | Indoor; above grade or buried, with the model-specific requirements and accessories. |
| GB-75-B | 50 GPM; 730 lb grease capacity at 99%; 125 gal liquid capacity; 138 lb product weight. | Indoor or outdoor; above grade or buried. |
| GB-250-B | 75 GPM; 1,560 lb grease capacity at 99%; 277 gal liquid capacity; 280 lb product weight. | Indoor or outdoor; above grade or buried. |
These are exact current configuration examples, not a complete selection table. Schier also lists alternate configurations for the same base families. The suffix and current document matter.
Listings and local acceptance
Schier's current product records state that these named configurations are listed by IAPMO to ASME A112.14.3 and CSA B481.1. A product listing does not by itself settle the local permit, sizing or approval decision. Confirm the exact listed configuration and ask the authority and project professional whether it is accepted for the address.
Installation questions to resolve
- Is the full model and suffix correct for the required flow and grease capacity?
- Is the proposed above-grade, buried, indoor or outdoor configuration documented for that model?
- Which finish cover, riser, support, anchor, pumpout and connection accessories are required?
- What access must remain for inspection and complete maintenance?
- What do the local sewer and building authorities require for plans, sizing, venting, sampling and inspections?
Pricing and warranty boundaries
This page does not publish national equipment or installed-price ranges. Obtain a dated quote for the exact model and accessories, freight, excavation or slab work, plumbing, restoration, permits and inspections.
Schier markets a lifetime guarantee, but the written terms and installation conditions control. Do not treat the phrase as proof of a 20- or 30-year service life, and do not assume the same coverage applies to every component or installation.
Frequently Asked Questions
Do Schier model numbers equal grease capacity in pounds?
No. Current product records show that the model name does not provide a reliable grease-capacity conversion. Use the exact model or configuration page and its current technical data.
Can Great Basin units be installed indoors or outdoors?
It depends on the model and configuration. The current GB2-C record describes indoor above-grade or buried use. Current GB-75-B and GB-250-B records describe indoor or outdoor, above-grade or buried configurations.
Are all Great Basin specifications interchangeable?
No. Base models and alternate configurations can have different flow rates, capacities, components and intended markets. Match the full model suffix to the current product record and submittal.
Does Schier's lifetime guarantee prove a service life?
No. A guarantee and an expected physical service life are different claims. Read the current written guarantee and installation conditions for the exact product; do not convert the guarantee into an unsupported lifespan prediction.
How should a Schier interceptor be sized?
Use the sizing method accepted for the project, then confirm the exact model's flow rate, grease and liquid capacities, installation configuration, covers, connections and access in current Schier documents.
