Summary
Frost free hydrants should be used strategically. In large open areas where stock watering is required - absolutely. But nowhere else. Expect maintenance of valves, and replament every decade or two. This is especially challenging if other lines such as electrical or internet complicate routing. Conclusion: do not use freeze-proof hydrants unless absolutely necessary. Absolutely necessary means ONLY daily supply in freezing weather. Not summer watering/pools/filling. Those should be in non-frost areas, or rolled up in winter. Long supply line is cheap ($100 for 1000 feet [7])
