Water hammer and hydraulic shock can damage pumps, piping systems, and critical equipment while creating excessive vibration, noise, and maintenance costs.

Download this case study to learn how a high-capacity wastewater treatment facility operating at tens of millions of gallons per day solved persistent water hammer issues by replacing conventional dual-disc check valves with DFT® ALC® Axial Flow Wafer Check Valves.

In this real-world application, plant personnel experienced:

• Reduced water hammer and hydraulic shock
• Less system vibration
• Significantly lower operating noise levels
• Improved pump and piping protection
• Greater system reliability

Following installation, operators reported a noticeable reduction in both vibration and plant noise. One operator remarked:

"The system became so quiet we wondered if the pumps were running."

This case study provides a side-by-side comparison of DFT's spring-assisted axial flow design versus traditional dual-disc check valves and demonstrates why many water and wastewater facilities choose silent check valve technology to improve performance and protect infrastructure.

• Why conventional check valves contribute to water hammer
• How silent, non-slam check valves improve system performance
• The operational benefits achieved at a large wastewater treatment facility
• Best practices for reducing hydraulic shock in pumping systems
