For high-traffic commercial restrooms, Zurn’s AquaSpec® deck-mount lavatory faucet is a solid choice. Constructed of a durable, lead-free cast brass body, AquaSpec® faucet valves 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… and it’s backed by our limited lifetime warranty. The 4-inch centerset Z81104-XL features a 4-inch integral cast spout. It has integral shanks, vandal-resistant, color-coded 4-inch wrist blade handles, and a polished chrome-plated finish. It comes with a standard 2.2 gpm pressure-compensating aerator. Alternate pressure-compensating flow rates are as low as a water-conserving 0.35 gpm with vandal-resistant, spray, aerator, or laminar flow outlets and ZurnSHIELD™ options. When you’re outfitting a commercial restroom or any other type of lavatory, the Z81104-XL is a perfect, long-lasting solution.
