1/4" Plastic Cap Snifter Valve, Black, Lead-Free

Campbell 1/4" Plastic Cap Snifter Valve – Dependable Air Admission for Pressure Tank Systems

The Campbell 1/4" Snifter Valve with plastic cap is designed to support proper air volume control in submersible pump systems using a standard air-over-water pressure tank. Installed in the drop pipe above the check valve, it works in conjunction with a bleeder orifice and air volume control to admit air into the tank during pump shutdown, helping maintain consistent pressure and prevent waterlogging.

Engineered for Function and Durability

This snifter valve is manufactured with a corrosion-resistant plastic cap and lead-free components, meeting current potable water requirements. Its simple but effective mechanism ensures a reliable air draw with every pump cycle, critical for preserving pressure tank integrity and optimizing pump performance over time.

Contractor-Grade Features

• 1/4" Male Pipe Thread (MPT) – Standard sizing for compatibility with typical drop pipe installations.
• Lead-Free Brass and Plastic Construction – Suitable for use in systems carrying potable water, meeting lead-free compliance standards.
• Built-in Check Mechanism – Allows air to enter but prevents water backflow, supporting consistent tank pressurization.
• Plastic Cap Included – Resists corrosion in high-moisture environments while protecting the valve seat.

Specifications

• Valve Size: 1/4" MPT
• Material: Brass body with corrosion-resistant plastic cap
• Use Case: Air admission valve for submersible pump systems with bleeder and AVC
• Application: Water well and pressure tank systems
• Compliance: Lead-free (meets NSF/ANSI/CAN 372)

Installation Guidance

The valve should be installed in the drop pipe above the bleeder orifice, approximately 5 feet below the well seal or pitless adapter. It requires threading into place and should be torqued carefully to avoid overtightening. Always pair with a functioning bleeder valve and air volume control to ensure the system operates as designed.

This component is intended for use by qualified technicians familiar with deep well jet and submersible pump systems. Proper system design and layout are essential for the snifter valve to function correctly.

Applications

• Submersible pump systems with bleeder valves and AVCs
• Residential and light commercial water well systems
• Applications requiring air replenishment in standard hydro-pneumatic tanks
