Kitchen Faucet Leak Fix
Most faucet leaks come from worn cartridges, washers, or O-rings. With basic hand tools, you can diagnose the faucet type, swap the failed part, and reassemble for a drip-free result. Shut off water, protect faucet and countertop finishes, and take photos as you go.
- Identify faucet type (cartridge, compression, ceramic disk, or ball).
- Shut off supply valves and plug the drain.
- Remove handle/trim to access the cartridge or stem.
- Match replacement parts by brand/model or bring the old part to the store.
- Reassemble carefully and test for drips at low and full pressure.

How Hard Is It to Repair a Bathroom or Kitchen Faucet?
Basic leaks are beginner-friendly if you can identify the faucet type and access the cartridge or stem. The trickiest part is removing stuck trim without scratching the finish and matching replacement parts. Expect the job to go quickly if you have the exact part; otherwise plan for a store run. Call a pro if the shutoffs won’t close, the valve body is corroded, or you see signs of supply line damage.
Step-by-Step: Replace a Faucet Cartridge
Step 1 — Shut Off Water and Prep the Area
Turn off the hot and cold valves under the sink; open the faucet to relieve pressure. Plug the drain so tiny screws don’t vanish. Lay a towel to protect the cabinet and finish — you’ll thank yourself later.
Step 2 — Remove Handle and Access the Valve
Pry off the small cap to reach the handle screw, then remove the handle and any trim. If trim sticks, rock gently — don’t pry against the finish. Take a photo of the valve orientation before removing anything else.
Step 3 — Extract and Match the Worn Part
Loosen the retaining nut or clip, then pull the cartridge or stem straight out. Compare part numbers/shape to the package or bring it to the store. Clean the valve body and apply a light coat of silicone grease to new O-rings.
Step 4 — Reinstall, Reassemble, and Test
Seat the new cartridge in the same orientation and secure with the clip or retaining nut. Reinstall trim and handle; use plumber’s tape on any threaded spout or supply connections. Turn water on slowly and test at low and high pressure, checking for drips around the base and spout.
Pro Tips for Bathroom & Kitchen Faucet Repair
- Snap a photo at each disassembly step for foolproof reassembly.
- Protect chrome with tape/cloth under wrench jaws.
- Grease O-rings lightly — too much attracts grit.
- If shutoffs seep or won’t close, replace them before the faucet work.
- If handles feel gritty, flush lines by removing the aerator and running water.
- Keep the old part bagged and labeled for future reference.
- Consider full faucet replacement if corrosion is severe or brand parts are costly.
