Step 8 · Reassemble Faucet
Reinstall the faucet components in the reverse order of their removal. For cartridge faucets, insert the new cartridge, ensuring it's properly aligned, and secure it with the retaining clip or nut. For ball faucets, place the cam, packing, and ball, then screw on the cap. For compression faucets, reinstall the stem assembly. Lubricate O-rings with plumber's grease as you go.
