Step 6 · Reassemble the Faucet
Reassemble the faucet components in the reverse order of disassembly. Start by re-inserting the U-shaped retaining clip into the slot at the top of the valve body, ensuring it snaps securely in place over the new cartridge. Next, slide the faucet sleeve back over the valve body, followed by the escutcheon plate. Secure the escutcheon plate with its two screws, being careful not to overtighten and crack the plate. Finally, push the handle back onto the valve stem, aligning it properly, and tighten the set screw with your Allen wrench or screwdriver to secure it. Pop any decorative cap back on if your model has one.
