• Here’s the most efficient way to identify out-of-service hydrants.
  • Simply slip a durable plastic HYDRA-SIGN® over the waterway outlet when you discover the outage.
  • The brightly-colored sign quickly tells fire and water department crews this hydrant is “OUT OF SERVICE”.
  • Signs are sized for 2.5″ outlets as well as main steamer connections, and come in standard colors of high visibility red, orange, and yellow.
