To fix a leaking pipe beneath your sink, start by placing a bucket underneath the P-trap and closing the wall water supply valves. Inspect the slip-joint nuts and P-trap connections; hand-tighten loose nuts or unscrew the assembly to replace degraded rubber slip-joint washers. If the leak originates from a cracked tailpiece or corroded metal pipe, remove the damaged component and install a replacement PVC or brass tailpiece. Verification: Open the water supply valves and run the faucet to verify that all under-sink joints are completely dry.
