Why should you fully open a dry barrel hydrant?

Fully opening a dry barrel hydrant is critical to prevent damage to interior fittings and the closure device. When a hydrant is only partially opened, it can lead to water flowing in a manner that puts excessive stress on the internal components. This may result in wear, potential breakage, or malfunction of the closure mechanism.

Moreover, fully opening the hydrant ensures that the internal parts are properly lubricated and functioning as designed, thereby prolonging the life of the hydrant. Additionally, any debris or buildup in the hydrant that can be washed away by the full flow of water will also help maintain its operational efficiency.

While there are other benefits to consider, such as providing adequate drainage and meeting emergency access needs, the primary concern that underscores the importance of fully opening a dry barrel hydrant is to safeguard the integrity of the internal mechanisms which are vital for its functionality.
