The Zurn Z81000-XL is a 4" centerset single control lavatory faucet that mounts through pre-drilled sink holes and connects to standard lavatory risers. Professional installation by a licensed plumber is recommended.
Key Installation Requirements:
- Sink with pre-drilled 4" centerset faucet holes
- Hot and cold lavatory supply lines (not included)
- 1/2" NPSM coupling nuts for standard lavatory risers (included)
- Maximum water pressure of 125 PSI
- 1-1/4" grid strainer (-G) or pop-up drain (-P) available as optional suffixes (standard unit ships with pop-up hole plugged)
Important Notes Before Installing the Z81000-XL:
- The pop-up hole comes plugged on the standard Z81000-XL. Order the factory-configured model with the -G (1-1/4" grid strainer) or -P (1-1/4" pop-up) suffix if a drain is required.
- Flush the supply lines before connecting. The aerator may need cleaning at startup.
- Set the red temperature limit ring on the ceramic cartridge to cap the maximum hot water temperature.
- Use only genuine Zurn replacement parts for service.
- Always refer to the official Zurn Z81000-XL Spec Sheet for flow options, drain options, and compliance details.
Basic Installation Overview:
- Shut off the hot and cold water supply.
- Insert the faucet shanks through the pre-drilled sink holes and secure with the included mounting hardware.
- Connect the lavatory supply lines to the shanks using the 1/2" NPSM coupling nuts.
- Install the drain assembly, if used.
- Turn on the water, check all connections for leaks, and flush the lines.
- Remove and clean the aerator if flow is clogged or deflected, then reinstall it and test the maximum temperature.
