**Yes—compact grease traps, also called grease interceptors, are available and can be installed on a home’s kitchen drain, subject to local plumbing requirements.** Many are marketed for commercial kitchens, but small models exist. For example, Zurn’s GT2700-4 is rated for 4 gallons per minute and holds 8 pounds of grease. That is an example of an available size; a plumber should size yours for the sink’s discharge. [Zurn specification sheet](https://files.zurn.com/spec-sheets/gt2700.pdf)

A correctly sized, installed and maintained interceptor **can reduce the kitchen grease reaching your pipes and septic tank**. It needs to sit upstream of the section that clogs, with proper venting, flow control and access for cleaning. It will not remove existing deposits.

The tradeoff is maintenance: you must regularly remove the trapped grease and solids. Cleaning frequency depends on the unit’s capacity and how much grease enters it. Once its grease capacity is exceeded, grease can pass downstream again. [Schier owner’s manual](https://product-assets.schierproducts.com/asset/OhBhLkLYlD8KmuSDvACZx5c1suyiygSLjdEQ7Cph.pdf)

For your situation, I would take these steps:

- **Have a plumber or septic professional identify the exact blockage location and inspect the old system.** Twice-yearly recurrence warrants checking whether pipe condition or drainage problems also contribute.
- **Reduce grease entering the sink.** Collect cooking fats for disposal and wipe greasy pans and dishes with paper towels before washing. [Texas environmental agency guidance](https://www.tceq.texas.gov/assistance/water/wastewater/fog/home_fog.html)
- **Ask about a small interceptor once the blockage is diagnosed.** Have the plumber confirm sizing, installation requirements and cleaning access before buying one.

Also, EPA recommends against routine bacterial or chemical septic additives: the system already contains microorganisms, and additives can be ineffective or harmful. Your monthly additive should not be relied on to prevent grease clogs. [EPA septic guidance](https://www.epa.gov/septic/frequent-questions-septic-systems)
