What is the recommended break time when replacing packing in the stuffing box?

When replacing packing in the stuffing box, a break time of 24 hours is generally recommended to ensure the packing material is properly set and seated. This duration allows for any necessary adjustments to be made after initial tightening, which helps to achieve an effective seal and minimizes the risk of leakage.

During this break-in period, the packing can settle under the pressure of the system and any minor adjustments can be made to ensure optimal performance. Rushing this process can lead to inadequate sealing, excess wear on components, or premature packing failure. Thus, allowing a full 24 hours helps ensure the reliability and efficiency of the stuffing box in the water distribution system.
