Step 6 · Reassemble the Faucet
Re-install the components in the reverse order of removal. Start by inserting the U-shaped retaining clip back into the slots at the top of the valve body; you should feel it click into place. Slide the stop tube back over the cartridge. Position the escutcheon plate against the wall and secure it with its two screws, being careful not to overtighten. Slide the handle back onto the cartridge stem, align it properly, and tighten the set screw with your Allen wrench or screwdriver. Finally, press the decorative cap back onto the handle.
