    You'll have to determine exactly where it's leaking, shut off the water and dismantle the problem area.

    If it's the valve, and my first guess would be the valve, you only have to remove the handle and replace the black rubber washer on the end of the stem. Take it to the store with you to be sure of buying the correct washer. Store staff should be able to assist you.

    If it's a pipe join, dismantle, replace any parts that could be damaged and use plumbers tape on all pieces as you reassemble.

    If it is leaking in incoming water lines, use Teflon tape in all joints. If the drain lines are leaking, use silicone and put it back together.

    Is the faucet dripping? Is there water under your sink? Is the basin leaking?

    It’s from the hot and cold water turn knobs and falling through cracks in counter when water splashes out! Maybe bucket basin is to small.... When we first built this system I never leaked but as we started turning knobs more and more maybe some how part of the got loose! Tried tightening but still water leaking...

    Sometimes if you over tighten the nut, it actually causes the faucet to leak more because the washer becomes deformed. Try loosening it slightly. You could rebuild the faucets with new washers and packing, which may or may not work. I would replace them with ball valves, which are more reliable and less likely to leak.
