Frequently Asked Questions

Is the RGV market large enough to support a dedicated backflow testing business?

Yes. The McAllen-Edinburg-Mission metro area alone has over 900,000 residents with growing commercial infrastructure. Combined with Brownsville, Harlingen, and the agricultural sector, the RGV can support multiple full-time testing operations.

Do I need to speak Spanish to work in the RGV?

It's not required, but it's a major competitive advantage. Many property owners, maintenance staff, and business managers are more comfortable communicating in Spanish. Bilingual service builds trust and opens doors that monolingual competitors can't access.

How does agricultural irrigation testing differ from municipal?

Agricultural systems may fall under irrigation district jurisdiction rather than municipal water utility oversight. Requirements, forms, and submission processes can differ. Verify whether the property connects to a municipal supply or irrigation district water before testing.
