## Regional RGV Technical Considerations
1. **BPUB Water Hardness (12–18 GPG)**: High dissolved calcium/magnesium causing rapid water heater element burnout and heavy pipe scaling.
2. **Expansive Clay Subsoil**: Montmorillonite clay expansion cycles in South Texas snapping underground copper and cast iron foundation pipes.
3. **BPUB Municipal Compliance**: Mandatory thermal expansion tanks, T&P safety discharge lines, and permit filings under TSBPE Master License #M-42198.
