Repair or replacement of faucet components, rather than replacement of the entire unit, saves money and resources. Zurn’s solenoid rebuild kit (Part no. P6900-SRK) is used to repair AquaSense® sensor faucet solenoids. Zurn sensor faucets contain an infrared proximity sensor that accurately detects the user for precise hands-free operation. When you need a replacement part for repair or maintenance of a faucet, trust Zurn for genuine, reliable parts.
