Water Leaking From the Valve Under Your Sink? Try the Old Plumber’s $4 String Fix

Water leaking from the shutoff valve under your sink doesn’t always mean the whole valve needs to be replaced. If the drip is forming around the valve stem just behind the handle, the problem may be an old packing seal — and the fix can cost about $4. In this video, Frank shows an old-school plumber’s repair using graphite valve stem packing, the inexpensive string-like material designed to seal around the moving stem of older multi-turn shutoff valves. You’ll learn how to find the true source of the leak, why simply tightening the packing nut sometimes works, when fresh packing is needed, and how plumbers used to repair a worn seal instead of replacing the entire valve. You’ll also see why a valve that stayed dry for years can suddenly start leaking after you turn it, how to avoid damaging the pipe while tightening the packing nut, why thread-seal tape won’t fix this type of leak, and how to tell when a valve really does need replacement.

From plumbing and drains to appliances, leaks, moisture, doors, fixtures and everyday home maintenance, Frank looks for the overlooked fix first. Always shut off the water upstream and relieve pressure before removing a packing nut. If the valve body is cracked, badly damaged, heavily corroded, or the upstream water supply cannot be reliably shut off, stop and call a qualified plumber. Have an old shutoff valve under a kitchen sink, bathroom sink or toilet? Tell me where it started leaking — and whether the drip appeared right after someone finally turned the valve.
