1-1/4" Brass Spring Foot Valve, Lead-Free

1-1/4" Brass Spring Foot Valve – Dependable Backflow Prevention for Water Systems

The 1-1/4" Brass Spring Foot Valve is a reliable solution for maintaining directional flow in pump-fed water systems. Constructed from lead-free red brass, this foot valve is engineered for use in potable water applications and built to withstand continuous exposure to pressurized and corrosive environments. Its integrated spring-loaded check mechanism ensures consistent sealing to prevent backflow when the pump is off.

Product Highlights

• Lead-Free Brass Body: Red brass construction offers excellent resistance to corrosion while meeting NSF/ANSI 61 standards for potable water use.
• Spring-Loaded Internal Check: Stainless steel spring provides consistent sealing force for reliable shutoff.
• Threaded Inlet: Standard FNPT connection for easy integration into existing suction lines.
• 200 PSI Working Pressure: Rated for systems requiring high-pressure performance in residential, agricultural, or light commercial settings.
• Temperature Range: Operates effectively up to 190°F.

Installation Considerations

This valve installs vertically at the end of the suction line, typically submerged in a well, reservoir, or tank. For best performance, install the valve below the water line and ensure the surrounding intake area remains free of debris. Use pipe thread sealant or Teflon tape to secure connections and test for pressure integrity before startup. Although installation is straightforward, professional installation is recommended to guarantee correct flow orientation and seal integrity under pressure.

Applications

• Shallow well and deep well pump systems
• Surface water intake lines
• Irrigation or booster pump suction lines
• Non-potable and potable pressurized water systems

Professional Notes

Contractors rely on this type of foot valve to protect pump integrity by keeping the suction line primed and preventing system backflow. The spring mechanism ensures rapid closure to reduce water hammer and reverse flow, and the brass construction stands up to tough field conditions without deteriorating over time. It's a practical component for both service and new installation jobs where long-term reliability is critical.
