No lock stopped thieves from stealing his brass irrigation valves for scrap — so the farmer swapped every valve for cheap plastic ones nobody would bother stealing.
the problem
a security threat targets an asset specifically because of its resale value, and no amount of access control stops someone determined enough to get it
background
California farms across the Central Valley faced a persistent wave of irrigation-equipment theft driven entirely by scrap-metal prices: brass valves, copper wire and aluminum pipe could be cut out, hauled off and sold to scrap yards for real cash, with metal theft rates spiking as much as 400% during price peaks. Farmers responded with standard security measures — locks, fencing, security cameras, neighborhood Farm Watch programs — but none of these addressed the actual reason thieves kept coming back: a functioning brass valve was worth real money at any scrap yard, so raising the difficulty of stealing it didn't eliminate the incentive, it just meant thieves needed a bit more effort or a different farm.
Dave Santos, a farmer in Patterson, California, had brass irrigation valves stolen repeatedly despite standard security precautions, each theft costing not just the replacement expense but downtime and crop-watering disruption. Rather than continue investing in better ways to guard valves that were valuable to steal, he addressed the value itself.
the move
Santos replaced his farm's brass irrigation valves and fittings with plastic PVC equivalents — components that cost more upfront and wear out faster in service than brass, but carry essentially no resale value at any scrap yard, eliminating a thief's financial reason to target them at all.
the payoff
The valve theft stopped, without any additional spending on security, guarding or surveillance — the fix worked by removing the underlying incentive rather than raising the cost of access, and the approach has since been adopted by other California growers facing the same scrap-metal theft problem on their own irrigation systems.
what came after
The brass-to-PVC valve swap is cited in agricultural security circles as a clear example of solving a resale-driven theft problem by eliminating resale value rather than hardening access — the same underlying logic, replacing a scrap-valuable material with a functionally equivalent but worthless one, is now recommended for other repeatedly-stolen infrastructure like copper wiring and catalytic converters in high-theft regions.
