- Brand matters. Reports of life from 1-5 years for really crappy ones, others are more like decades of life [1]
- OSE experience - galvanized pipe corrodes over 9 years - see bottom of hydrant all corroded in album [2]. In album picture, brass seems to eat galvanized through electrolytic action - [3]
- PVC and plastic lasts indefinitely [4]
- Galvanized pipes last between 20-50 yeaars [5]
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 [6])
