Replacing a Worn-Out Faucet Washer at Home
A faucet that drips steadily, even when fully closed, is almost always caused by a worn rubber washer inside the handle assembly, not a sign that the whole fixture needs replacing. This is one of the more approachable home repairs, since it generally requires only a few basic tools and a replacement part that costs very little compared to a plumber’s call-out fee.
Shut Off the Water Before Touching Anything
Every faucet repair starts with locating the shutoff valves beneath the sink and turning them fully closed. Afterward, turn the faucet handle on briefly to release any remaining pressure in the line, and place a towel in the sink basin to catch drips and protect against scratches from dropped tools during the repair.
Remove the Handle Carefully
- Pop off the decorative cap on top of the handle, if present
- Remove the screw underneath holding the handle in place
- Lift the handle straight off, noting how it was oriented
- Unscrew the packing nut to expose the stem and washer
Keeping track of the order parts come off in, perhaps by laying them out in a line on the counter, makes reassembly far simpler than trying to remember the sequence from memory alone afterward.
Replace the Washer With a Matching Size
The washer sits at the base of the stem, held by a small screw. Taking the old washer to a hardware store, rather than guessing at the size, ensures the replacement fits properly, since faucets vary enough between manufacturers that an incorrect size often leads to a drip returning within weeks.
Inspect the Seat While You’re In There
While the faucet is apart, it’s worth checking the valve seat — the surface the washer presses against — for pitting or roughness. A damaged seat can cause a new washer to wear out again quickly, and in that case a seat wrench or a seat replacement might be needed alongside the washer itself.
Reassemble and Test Gradually
Reverse the disassembly steps, tightening firmly but without overdoing it, since excessive force can crack components that are often made of relatively soft metal. Turn the water back on slowly, and check for leaks both at the handle and underneath the sink before considering the repair complete.
Know When the Fix Isn’t Enough
If a drip returns shortly after a fresh washer is installed, the problem may lie elsewhere in the faucet assembly rather than with the part you just replaced. Persistent leaks despite a correct repair are usually a sign it’s time to consult a professional rather than repeatedly replacing the same component with no lasting improvement.
Keep a Couple of Spare Washers on Hand
Once you’ve identified the correct washer size for your faucets, buying a few spares at the same time saves a future trip to the store when the same issue inevitably resurfaces on another faucet in the house. A small parts drawer with these basics turns future repairs into a quick task rather than a planning exercise.
