Repair or replacement of faucet components, rather than replacement of the entire unit, saves money and resources. Zurn's 4-inch center set cover plate (Part no. P6900-CP4) fits AquaSense sensor faucets to cover extra holes or gaps. 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.
