I need help fixing a leaky sink. Are there any DIY tips to help?

Start by shutting off the water valves under the sink. Then, loosen the sink's drain flange and inspect it for cracks or damage. If it's cracked or damaged, you'll need to replace it to fix the leak. If not, then you should check the rubber gasket around the drain flange, and replace it if necessary. Additionally, check the water supply lines for any signs of leakage, and replace them if necessary. Finally, re-assemble the drain flange and tighten the nuts. That should help to fix the leaky sink.
