Providing a comprehensive approach to maintaining air release valves and isolation valves in water and wastewater systems.

Maintaining and/or replacing air release valves (ARV) to help protect a pressure pipeline’s system and maintain its efficiency is essential to preventing premature failure. ARVs play a critical role in pressured pipelines, quickly venting large volumes of air during filling or startup, as well as normal operating conditions, and allowing air back into the pipeline during emptying, thus eliminating negative pressure. Malfunctioning ARVs can cause air lock and pipeline collapse. In wastewater force main applications, malfunctioning ARVs can promote the conversion of H2S gases to H2SO4, sulfuric acid, thus accelerating damage to the crown of a sewer force main resulting in premature failure and decreasing remaining lifetime use.

CPM Pipelines’ confined space certified technicians perform ARV assessment, maintenance, and installation helping clients protect their pipeline’s system and maintain efficiency, preventing possible further damage. Our inspection/assessment includes a final report confirming valve manufacturer and model, size, cover and vault condition, components disassembled during inspection, isolation valve condition, drain plug condition, water intrusion or drainage issues, parts replaced or recommended, and overall condition analysis. Proper maintenance extends the life, and ensures the ARV is functioning properly to prevent damage to other components in the system.

We offer high quality valves and fittings from industry leading manufacturer H-TEC providing long-term solutions for distribution and collection systems.
