Why should isolation valves be installed at frequent intervals in distribution piping?

The installation of isolation valves at frequent intervals in distribution piping is crucial for allowing specific sections of the water main to be shut off for maintenance. This provides operational flexibility, enabling crews to perform repairs or replacements without needing to disrupt the entire system. It also minimizes service interruptions for customers by isolating only the affected sections, enhancing the overall efficiency of maintenance activities.

Frequent installation of isolation valves contributes to system reliability by permitting quick isolation of leaks or failures. This practice is essential for both routine maintenance and emergency responses, ensuring that the remaining sections of the system can continue to operate normally while work is being conducted. Consequently, this strategy not only helps maintain service levels but also extends the lifespan of the infrastructure by facilitating timely repairs and minimizing the risk of larger system failures.
