Delta Faucet 578-ssmpu-dst Single Handle Lavatory Faucet

Product Description

The DELTA FAUCET 578-ssmpu-dst is a single-handle lavatory faucet finished in stainless and equipped with a metal pop-up drain assembly. It uses a diamond-coated ceramic disc valve designed for long service life rated to five million cycles. InnoFlex PEX waterways route water through flexible tubing that stays isolated from metal faucet components, reducing the risk of contamination from internal metal contact. WaterSense certification confirms the faucet meets EPA water-efficiency standards without sacrificing flow performance. This unit is installed by licensed plumbers and qualified finish plumbers on residential bathroom sink applications.

The 578-ssmpu-dst is suited to residential bathroom lavatory installations where a single-handle configuration is preferred for ease of temperature and volume control. The stainless finish offers corrosion resistance appropriate for wet-area applications. The included metal pop-up drain provides a coordinated, tool-adjustable drain assembly that integrates directly with the faucet body. This faucet is appropriate for countertop or vanity deck mounting in single-hole or compatible deck configurations.

Installation Notes

Installation is performed by a licensed plumber under applicable IPC and local plumbing code requirements. Shut off the supply stops and relieve line pressure before removing any existing faucet or supply connections. The metal pop-up linkage requires adjustment at the pivot rod and clevis strap to set proper stopper travel. Do not overtighten supply line connections to PEX waterway inlets, as these fittings are designed for hand-tight-plus-quarter-turn torque only per manufacturer assembly guidance.
