Explore the specialized world of private water supply systems and residential fire protection in this informative episode. While these systems are technically out of scope for standard home inspections, understanding their basics helps you provide better service and appropriate recommendations.

The well systems segment covers everything from traditional hand-dug wells to modern drilled wells reaching hundreds of feet deep. You'll learn about well location requirements, including minimum distances from septic systems and contaminate sources. We explain why wells should be 12-18 inches above grade with proper capping and sealing.

Typical drilled well components receive detailed coverage: casings, screens, submersible pumps, jet pumps, pitless adapters, and pressure tanks. You'll understand the differences between precharged captive air tanks and older air-over-water steel tanks, and learn to identify waterlogged tank conditions. The episode explains pressure switch operation, including typical cut-on and cut-off levels and proper pressure settings.

We discuss well pump service life expectations, replacement costs, and factors affecting longevity. You'll learn visible clues that indicate potential well problems, from low water pressure causes to water quality issues.

The water quality segment covers common problems like hard water, sulfur content, and bacterial contamination. We explain when water testing is recommended and what types of contaminants to consider based on surrounding land use.

Fire suppression systems receive brief coverage, acknowledging that while IRC requires them in new construction, few jurisdictions have adopted this requirement. We explain why these systems are out of scope and the importance of recommending evaluation by qualified contractors.

This episode provides the background knowledge needed to disclaim these systems appropriately while still offering valuable guidance to your clients.
