Garden Valve Corrosion

The Vassar Farm Garden requires fairly heavy watering, because it’s in full sun all day long, so we lay in a set of drip lines connected through Y valves to a main feeder line running down one end of the plot. Plastic valves tend to be overly fragile, so this year I tried a few much larger full-flow ball valves with a metallic housing:

This valve lay on the ground (as they all do) just inside the gate and served as an occasional supply for a short hose with the hand sprinkler head. I don’t know what’s driving this corrosion, but it’s eating the external threads as well as the valve bore.

Overall, I’m unimpressed…
