A leaky faucet is not just annoying. A single faucet dripping once per second wastes over 3,000 gallons of water a year. The fix usually costs less than ten dollars in parts and takes about twenty minutes if you have the right information going in. The hard part is not the repair itself, it is figuring out what kind of faucet you have, because each type comes apart differently.
Here is how to handle the three most common faucet types you will find in any home built after 1980.
Step 1: Identify your faucet type before buying anything
There are four main faucet types: compression (two separate handles, old style), ball (single round handle that pivots in all directions), cartridge (single or double handle with a sliding cartridge inside), and ceramic disc (single lever, wide cylinder body). Each needs a different repair approach.
Turn off the water supply under the sink before doing anything else. Turn both handles to the on position to let any remaining pressure drain out. Now you can take the handle off safely. Most handles are held by a screw under a decorative cap, pop the cap with a flathead, remove the screw, and pull the handle straight up or wiggle it gently side to side.
Step 2: Fix a compression faucet (two-handle, older homes)
Compression faucets are the oldest design. They have rubber washers at the bottom of a stem that press against a seat to stop water flow. When the washer wears out, the faucet drips. Once you have the handle off, use a crescent wrench to unscrew the packing nut and pull out the stem. At the bottom of the stem is a rubber washer held by a brass screw. Remove the screw, swap the washer for a new one the same size, reassemble in reverse order. Rubber washer sets cost about three dollars for twenty assorted sizes, keep a set in your cabinet.
If the seat (the brass surface the washer presses against) feels rough when you run a finger around it, you can resurface it with a seat wrench or replace it entirely. A rough seat chews through new washers fast.
Step 3: Fix a cartridge faucet (single or double handle, most common today)
Cartridge faucets are the most common type in homes built after 1990. The cartridge is a plastic or brass cylinder that controls water flow. When it fails, the faucet drips or the handle gets stiff. Look up your faucet brand and model number, then buy the exact replacement cartridge, do not guess. Moen, Delta, and Kohler each use proprietary cartridges and they are not interchangeable.
With the handle off, you will see a retaining clip or nut holding the cartridge. Needle-nose pliers or a cartridge puller tool (cheap, worth it) let you pull the old cartridge straight out. Note the orientation before you pull, rotating it 180 degrees is the most common installation mistake and it makes hot and cold run backwards. Drop the new cartridge in the same orientation, reinstall the clip, replace the handle, turn the water back on slowly and test.
For pulling stubborn cartridges, a quality multi-tool set makes the job much cleaner. The HOTO tool kit includes the pliers and screwdrivers you need for this kind of repair without a cluttered toolbox full of gear you rarely use.
Step 4: Fix a ball faucet (single round handle)
Ball faucets have more parts than other types, a rotating ball, springs, seats, and O-rings, and they are more likely to leak from multiple points at once. The easiest fix is a ball faucet repair kit specific to your brand. The kit comes with all the small parts that commonly fail: springs, rubber seats, O-rings, and sometimes a new ball. Delta and Moen both sell their own kits for under fifteen dollars.
Unscrew the handle set screw (usually an Allen key), lift the handle, unscrew the cap and collar, and lift out the ball and cam. Replace all the small parts in the kit, reassemble, and you typically solve every drip issue at once rather than chasing leaks one at a time.
The repair that actually saves money
Most plumbers charge a minimum service call fee of $100 to $150 just to show up, before they touch anything. A cartridge replacement or washer swap that takes them fifteen minutes costs you that call fee plus parts. Doing it yourself costs $5 to $15 in parts and an hour of your time the first time you try it, less every time after.
If you are working through a home reset budget and looking for places to cut real costs, the Broke Mom Home Reset ($17) walks through exactly this kind of maintenance, the small fixes that prevent the big bills. A leaky faucet ignored long enough becomes water damage, which is not a twenty-dollar fix.
Turn off the water, identify your faucet type, buy the right part, and follow the steps above. Most people finish this repair faster than they thought possible and wonder why they waited so long to try it.
