A leaking sink cabinet bottom drain can be a major inconvenience, leading to water damage and mold growth. Fortunately, replacing a kitchen sink cabinet bottom drain is a relatively simple plumbing repair that can be completed in a few hours with the right tools and materials.

Tools and Materials You'll Need:

* Adjustable wrench * Plumber's putty * New sink drain assembly * Bucket or bowl * Rags or towels

Step-by-Step Instructions:

1. Gather Your Tools and Materials: * Ensure you have all the necessary tools and materials before starting the repair. 2. Turn Off the Water Supply: * Locate the water supply valves under the sink and turn them off to prevent any water flow during replacement. 3. Remove the Old Drain: * Place a bucket or bowl under the sink to catch any dripping water. * Use an adjustable wrench to loosen the nuts that hold the old drain assembly in place. * Carefully remove the old drain assembly. 4. Clean the Drain Opening: * Wipe the drain opening clean of any debris or old plumber's putty. This ensures a good seal for the new drain. 5. Apply Plumber's Putty: * Roll a rope of plumber's putty and shape it into a ring slightly larger than the drain flange. Place the putty ring around the drain opening. 6. Install the New Drain: * Insert the new drain assembly through the drain opening, ensuring the flange rests on the putty ring. * Tighten the nuts that hold the drain in place, using the adjustable wrench. Do not overtighten. 7. Reconnect the Water Supply: * Turn the water supply valves back on. 8. Check for Leaks: * Run water into the sink and inspect the drain for any leaks. If you find any, tighten the nuts further. 9. Clean Up: * Wipe up any excess water or putty.

Tips:

* If the old drain is heavily corroded or damaged, you may need to use a hacksaw to cut it out. * When tightening the nuts, use two wrenches to prevent the drain from spinning. * If you encounter any difficulties during the replacement, it's best to consult a licensed plumber.
