Introduction
A faucet handle that will not fully shut off, feels loose, or requires excessive force to turn is a common annoyance in NYC apartments, particularly in buildings with older fixtures. The problem usually comes down to a worn stem washer, a corroded valve seat, or depleted packing around the stem that allows water to seep past the handle. Fortunately, these components are inexpensive and replaceable without removing the entire faucet. Fixing the handle promptly prevents a drip from turning into a stream and avoids further damage to the valve seat.
Step-by-Step Instructions

Step 1 Turn Off the Water Supply
Shut off the hot and cold supply valves under the sink. If you are only fixing one handle, you only need to close the corresponding valve, but closing both prevents accidental scalding if you need to test. Open the faucet to drain residual water and relieve pressure. Place a towel in the sink basin to catch small parts like screws and washers. In some older NYC apartments, under-sink valves may be absent or non-functional — you may need to shut off water at the building main, which requires coordinating with your super.

Step 2 Remove the Handle and Stem
Pop off the decorative cap on the handle (it may pry off or unscrew). Remove the screw underneath and pull the handle off the stem. If the handle is stuck from mineral deposits, use a handle puller tool or wrap it in a rag and gently work it side to side while pulling upward. Once the handle is off, use an adjustable wrench to unscrew the packing nut (the first hex-shaped nut you see). Then unscrew the stem itself by turning it counterclockwise. Pull the entire stem assembly straight out.

Step 3 Inspect and Replace Worn Components
Examine the rubber washer at the bottom of the stem — if it is flattened, cracked, or hard, replace it with a new one of the same size. Remove the old washer by unscrewing the brass screw holding it in place. Also inspect the O-rings along the stem body; replace any that look worn or compressed. If the stem itself is visibly corroded or the threads are damaged, replace the entire stem assembly. Bring the old stem to the hardware store to find an exact match — stems vary by manufacturer and age.

Step 4 Check and Dress the Valve Seat
While the stem is removed, look inside the faucet body with a flashlight and feel the valve seat (the brass ring the washer presses against) with your finger. If it feels rough, pitted, or has a groove worn into it, even a new washer will not seal properly. Use a valve seat grinder (also called a seat dresser tool, available for about ten dollars) to resurface it — insert the tool, press it against the seat, and turn it several times to grind the surface smooth and flat. Wipe away metal shavings with a damp cloth before reassembling.

Step 5 Reassemble and Test
Apply a thin coat of plumber's grease to the new washer and O-rings before reassembling. Thread the stem back into the faucet body and hand-tighten, then snug the packing nut with a wrench — tight enough to prevent leaks around the stem but not so tight that the handle is hard to turn. Reattach the handle and decorative cap. Slowly open the supply valves and test. The handle should turn smoothly and the faucet should shut off completely with normal hand pressure. If it still drips, the valve seat may need professional replacement.
When to Call a Professional
Call a plumber if the valve seat is damaged beyond what a seat grinder can fix, if the stem is so corroded that it will not unscrew without risk of breaking the faucet body, or if the faucet body itself is cracked. In older NYC buildings with original brass fixtures, replacement parts may be difficult to source — a plumber who specializes in older buildings will have access to specialty suppliers and salvage resources. If the faucet is beyond repair, a pro can replace the entire unit and update the supply connections at the same time.
