Dry Hydrant Design #56 - Strainer w/Backflush Feature

One of the most important features of a dry fire hydrant design is the selection of suction strainer. When going with a barrel-style strainer, the best practice is to select a strainer that has a built-in back-flush feature that allows the contents of the pipe to be "pushed out" when the system is back-flushed by a pump operator. This feature is really important in a static body of water where there is a good chance of small fish and other aquatic life entering the strainer holes and living inside the pipe.
