Repair or replacement of faucet components, rather than replacement of the entire unit, saves money and resources. Zurn’s composite filter assembly (Part no. P6900-120BC) is made for AquaSense® and Aqua-FIT® sensor faucets. 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.
