A persistent drip or a sudden leak from your faucet disrupts the calm of any home and wastes valuable resources. Addressing how to fix a broken faucet quickly is more than a weekend project; it is a necessary maintenance task that prevents higher bills and water damage. This guide walks you through the diagnostic steps and repair solutions for the most common faucet failures.
Identifying the Type of Faucet and Leak
The first step in how to fix a broken faucet is correctly identifying the fixture type and the source of the leak. There are four primary faucet configurations: compression, cartridge, ceramic disk, and ball. Compression faucets use separate hot and cold handles, while cartridge, ceramic disk, and ball models operate with a single handle. Determining the type dictates the specific parts you will need for the repair. Similarly, the location of the leak—whether from the handle, the spout, or the base of the faucet—narrows down the exact faulty component.
Gathering Tools and Replacement Parts
Before turning off the water, assemble your tools to ensure a smooth repair process. You will typically need an adjustable wrench, a set of screwdrivers (flathead and Phillips), pliers, a basin wrench, and a plumber’s tape. For parts, purchase a repair kit specifically designed for your faucet model, which includes gaskets and O-rings. If you are replacing the entire valve, ensure you match the brand and model number to guarantee compatibility.
Shutting Off the Water Supply
Safety and cleanliness are paramount when learning how to fix a broken faucet, and this begins with isolating the water flow. Locate the shut-off valves under the sink and turn them clockwise to stop the hot and cold water lines. If no valves are present, you must turn off the main water supply to the house. Open the faucet handle to drain the remaining water from the pipes and relieve pressure, preventing splashes during disassembly. Disassembling the Faucet Mechanism With the water off, you can safely remove the faucet handle. Usually, a small screw located at the base of the handle or behind a decorative cap secures it. Once the handle is off, use a wrench to loosen the packing nut or retaining nut that holds the valve stem or cartridge in place. Carefully lift out the internal mechanism, inspecting the parts for cracks, mineral buildup, or worn seals that are causing the drip.

Common Leak Sources and Solutions
Most faucet failures fall into predictable patterns, making the fix straightforward once identified. If water seeps from the spout when the handle is off, the rubber washers or O-rings inside the valve seat are likely degraded. Handle leaks often stem from a loose nut or a failing cartridge seal. For a faucet that drips intermittently, mineral deposits may be preventing the seat from closing tightly, which can often be resolved by cleaning the component with vinegar.
