Basic materials/tools
Materials
- • Kitchen sink strainer or drain flange set
- • Plumber's putty or silicone compatible with the sink and strainer

Tools
- • Pliers, adjustable wrench, or strainer wrench

Before you start
- 1Check whether the old strainer is leaking, corroded, stuck, or connected to a disposal.
- 2Confirm the sink opening and drain layout before buying the replacement strainer.
- 3Plan leak checks after reassembly and again after normal sink use.
Watch out for

- Ignoring garbage disposal weight, alignment, or wiring proximity.
- Skipping leak checks around the strainer, trap, disposal connection, and cabinet floor.
