What is one advantage of repairing a leak under pressure?

Repairing a leak under pressure primarily helps to reduce the risk of contamination. When a water line has a leak, there is a potential for ground contaminants to enter the system, especially if the pressure in the pipes drops significantly or if the leak allows backflow from surrounding soils. By conducting repairs while maintaining the system under pressure, you minimize the likelihood of outside contaminants infiltrating the water supply.

This is critical in maintaining water quality and ensuring that the public receives safe drinking water. Additionally, keeping the system pressurized while addressing leaks prevents the need for extensive decontamination processes after a repair, further safeguarding the integrity of the water supply. While other factors such as time savings and operational costs may be considerations, the primary advantage linked to leak repairs under pressure is the protection of water quality and safety.
