Delta Faucet Co 521-PPU-ECO-DST Lavatory Faucet Chrome

Product Description

The DELTA FAUCET CO 521-PPU-ECO-DST is a single-handle lavatory faucet finished in chrome, designed for 4-inch centerset, 3-hole sink installations. It delivers 1.2 gallons per minute (GPM) at 60 psi, meeting WaterSense standards by using at least 20% less water than the industry baseline without sacrificing flow performance. The faucet features Diamond Seal Technology, which reduces internal leak points and is engineered to simplify installation. A rigid spout and integrated InnnoFlex PEX supply lines are included, reducing the need for additional fittings. A plastic pop-up drain assembly is also included. Licensed plumbers and experienced DIYers handle routine installation.

This faucet is suited for residential bathroom lavatory applications requiring a centerset layout with 4-inch hole spacing across 3 holes. The low-flow 1.2 GPM rating makes it appropriate for water-conscious installations in both new construction and remodel projects. ADA compliance broadens its application to accessible restroom builds and retrofits subject to accessibility codes. The included InnnoFlex PEX supply lines make it compatible with standard under-sink rough-in connections without separate supply line purchases.

Installation Notes

Installation should be performed by a licensed plumber or qualified tradesperson in accordance with local plumbing codes and the IPC. Shut off hot and cold water supply valves and relieve line pressure before beginning work. The integrated PEX supply lines should not be kinked or over-bent during routing to the shut-off valves.
