Types of <strong>Hydrant</strong>s<br />
Dry Barrel, are used in areas where freezing<br />
temperatures could damage the hydrant. It<br />
uses a valve at the base of the hydrant to<br />
control water flow to all outlets.<br />
When the dry barrel hydrant valve is closed<br />
or partially open, a drain allows the water<br />
to drain from the hydrant preventing<br />
damage from freezing.
