Repair or replacement of faucet components, rather than replacement of the entire unit, saves money and resources. Constructed of heavy-duty plastic, Zurn’s flow control assembly (Part no. Z80000-FC1.0) is made for AquaSpec® faucets with the flow control in the base of the spout. AquaSpec® faucets contain a unique, heavy-duty quarter-turn ceramic disc cartridge. The cartridge is so durable, you can expect it to last up to one million cycles. When you need a replacement part for repair or maintenance of a faucet, trust Zurn for genuine, reliable parts.
