Why Is My Faucet Dripping Even When Fully Shut Off?

A dripping faucet that won’t stop, even after you’ve cranked the handle as far as it goes, almost always points to worn or damaged internal components. It’s not a mystery, and it’s not random. Something inside the faucet has deteriorated to the point where it can no longer form a watertight seal. That said, knowing when to hand it off to a plumber in Richmond, VA can be the difference between a simple part replacement and a full faucet overhaul.

Five Faucet Components That Commonly Fail

Faucets are more mechanical than most people realize. When they fail to shut off completely, the issue almost always traces back to a specific part that’s worn down, corroded, or no longer sealing the way it should.

Depending on your faucet type, any of the following could be the source:

Worn washers

In compression faucets, rubber washers press against a valve seat to stop water flow. Friction wears them out with repeated use.

Damaged O-rings

Cartridge faucets rely on O-rings to seal the stem. When these degrade, water slips through even with the handle in the off position.

Corroded valve seat

The valve seat connects the faucet to the spout. Sediment buildup can corrode it, creating gaps where water escapes.

Loose or worn packing nut

If this piece is too loose, water can leak around the stem.

Worn-out cartridge

In single-handle faucets, a failing cartridge disrupts the internal pressure balance that controls water flow.

That Slow Drip Is Doing More Damage Than You Think

According to the U.S. Environmental Protection Agency, a faucet that’s leaking at one drip per second wastes more than 3,000 gallons of water per year. That’s equivalent to over 180 showers. The internal wear causing that drip also tends to accelerate once it starts, since the damaged seal gets exposed to constant pressure and friction.

Ignoring a drip can also lead to mineral deposits building up around the valve seat, making the eventual plumbing repairs more involved than a simple washer swap.

Signs the Faucet Needs a Professional Look

Some faucet repairs are DIY-friendly, like replacing a washer. But when the valve seat is corroded, the cartridge is cracked, or you’re dealing with a faucet that’s over 15 years old, the repair often involves more disassembly than it looks. A dependable plumbing company can assess the full condition of the faucet and advise on repair vs. replacement, which is worth knowing when the cost of parts starts approaching the cost of a new fixture.

What Homeowners Usually Ask

Q: Can a dripping faucet increase my water bill noticeably?

Yes. Even a slow drip adds up to hundreds of gallons monthly depending on frequency.

Q: Is it always the washer?

Not always. Faucet type matters. Ball, cartridge, ceramic disc, and compression faucets each have different failure points.

Q: Can I use plumber’s tape as a temporary fix?

Thread tape works on pipe connections, not on internal valve components. It won’t stop a faucet from dripping; you’ll need professional plumbing repairs.
