Repair or replacement of faucet components, rather than replacement of the entire unit, saves money and resources. Constructed of lead-free cast brass, Zurn’s thermostatic mixing valve (Part no. P6900-TMV-1-XL) works with AquaSense® sensor faucets for controlled mixing of hot and cold water under the deck providing a comfortable, owner-controlled user experience. 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.
