Faucet Cartridge Replacement
Faucet cartridge replacement fixes drips and stiff handles by swapping the internal valve that controls water flow and temperature. Cartridges wear out from friction and mineral buildup, and a new one restores smooth, drip-free operation. FlowFast connects you with an independent local plumber who will identify your faucet's cartridge type and replace it correctly.

Toilet & Faucet RepairRunning toilet or dripping faucet? Common causes, when repair beats replacement, and how to get connected with an independent local plumber.
View all Toilets & Faucets servicesInside most modern faucets, a cartridge does the job that old rubber washers used to do: it opens, closes, and blends hot and cold water as you move the handle. Single-handle faucets use one cartridge, while two-handle faucets use one per side. When the cartridge's internal seals wear or minerals score its surfaces, the faucet drips from the spout, the handle gets stiff, or the temperature becomes frustratingly hard to control.
The catch is that cartridges are brand- and model-specific, with different lengths, spline counts, and stem shapes that all look similar at a glance. Bringing the wrong one home from the store is the most common DIY frustration with this repair. FlowFast connects you with an independent local plumber who can identify the faucet brand and model, source the correct cartridge, and install it with the right lubricant and seating so the handle moves smoothly and the drip stops for good.
Warning signs
Signs you need this service
- The faucet drips steadily from the spout even when the handle is pushed fully to the off position.
- The handle feels stiff, gritty, or loose, or it takes extra force to turn the water fully off.
- Hot and cold seem reversed or hard to balance, which can mean the cartridge is installed wrong or worn out.
- You hear squeaking or grinding when moving the handle, a sign the cartridge's internal parts are scored.
What to expect
The process, step by step
The pro shuts off the fixture valves, removes the handle, and carefully extracts the old cartridge.
They identify the exact brand and model so the replacement cartridge matches perfectly every time, avoiding a second trip for parts.
The new cartridge is lubricated, seated properly, and secured, then the handle is fully reassembled and aligned correctly.
Water is restored and the pro checks for drips, smooth handle movement, and correct hot-cold orientation.
Prevention
How to avoid this problem
- Turn handles gently to the off position instead of cranking them, which shortens cartridge life considerably.
- Clean the aerator regularly so pressure buildup never stresses the cartridge seals unnecessarily or shortens their working life.
- Address small drips early, since a leaking cartridge can erode the valve body over time.
