A Bunn 57013 Check Valve manages one-way liquid flow to preserve consistent dispensing and reliable system function.
The check valve controls one-way fluid flow within the dispenser, preventing backflow that can disrupt dispensing consistency and internal system pressure. Its dome-style body and 0.281-inch connection size are designed to maintain proper sealing and fit, which is important for reliable beverage movement and sanitary operation.
The check valve may be failing if the dispenser shows irregular flow, pressure loss, backflow or inconsistent beverage output during operation. You might notice physical signs such as wear, cracking or leakage around the valve and environmental signs may include residue buildup or exposure-related deterioration from frequent moisture and cleaning chemicals.
