Dorman 926-335 Windshield Washer Anti-Drain Back Valve

The Dorman 926-335 Windshield Washer Anti-Drain Back Valve is designed to prevent windshield washer fluid from draining back into the reservoir when the pump is not in use. This small but essential component maintains proper fluid pressure in the washer system lines, ensuring instant washer spray when you activate the system.

Key Features:

• Prevents fluid drain-back to maintain system pressure
• Ensures immediate washer spray response
• Direct replacement for worn or failed original valve
• Durable construction resists washer fluid chemicals
• Easy installation in washer fluid line

This valve is a common wear item in windshield washer systems. When it fails, you may experience delayed washer spray or reduced spray pressure as the system needs to refill the lines each time. Replacing a faulty check valve restores proper washer system performance and ensures clear visibility when you need it most.
