How to Fix a Leaky Faucet
If you're dealing with a persistent drip or a steady stream of water from your faucet, learning how to fix a leaky faucet is a valuable skill that can save you money on your water bill and prevent water wastage. Fortunately, many faucet leaks can be resolved without the need for a plumber. In this guide, we'll walk you through the steps to diagnose and repair common faucet leaks, whether you have a dripping kitchen sink, bathroom faucet, or any other type of fixture. By following these simple instructions, you'll be able to address the issue and enjoy a leak-free faucet in no time.
Identifying the Source of the Leak
Identifying the source of the leak is the first step to fix a leaky bathroom sink faucet. Leaky faucets are not only an inconvenience, but can also lead to costly water damage if left unresolved. In just a few minutes of inspection, you can save money and protect your home from potential damage.
There are three common types of leaks that may occur in a single handle bathroom faucet: handle leakage, base leakage, and spout leakage. Knowing where the leak is coming from will help you determine the root cause and the appropriate steps to fix it. A damaged faucet cartridge is often the culprit behind a dripping faucet, but other issues may be at play as well.
We’ll delve into each type of leak for better understanding.
Handle Leakage
Handle leakage occurs when water drips from the faucet handle, which may indicate a damaged cartridge or worn O-ring. Signs of a damaged cartridge include water dripping from the spout even when the handle is off, difficulty adjusting the water temperature, hot water entering cold water outlets, and inadequately heated water at some faucets. Worn O-rings may also be the cause of handle leakage, with symptoms such as water at the base of the spout when the water is activated, leaking or dripping in a cartridge faucet, and deteriorated components such as rust or mineral deposits around the sink counter clockwise.
Handle leakage can result in water damage to floors, cabinets, and walls, increased water bills, mold and rot, structural damage, and health risks from pests and insects. Replacing damaged O-rings and cartridges and properly tightening the supply line nut can prevent handle leakage.
Base Leakage
Base leakage is characterized by puddling at the base of the faucet. This type of leak can be caused by a loose aerator, spout, or nut, or a damaged gasket. A loose aerator can be a contributing factor to a leaking faucet base, as water can flow from the top of the aerator and follow the spout down to the base, resulting in leakage through the mounting hole on the sink. Tightening the aerator or replacing it can help rectify the issue. If the problem persists, consider consulting a professional plumber.
Signs of a loose spout causing base leakage may include:
- Water seeping out through the base when the faucet is activated
- Puddles or moisture around the base of the faucet
- Mineral or rust deposits around the base
- A loose or damaged O-ring at the base of the spout
A small flat head screwdriver may be helpful in removing the spout for inspection.
Spout Leakage
Spout leakage is the third type of leak, characterized by water leaking from the spout. This may be due to a deteriorated valve seat or a malfunctioning cartridge. A deteriorated valve seat can result in spout leakage due to sediment buildup and corrosion of the seat, resulting in leaks around the spout.
Water dripping from the spout suggests that the internal valve is not closing off the water supply adequately, indicating that the faucet cartridge needs to be replaced. To fix the issue, remove the cartridge straight out and inspect it for damage. If necessary, replace the cartridge with a new one.
Leaky Kitchen Faucet Single Handle

By the end of this article, you'll have the knowledge and confidence to tackle the problem head-on, ensuring a drip-free kitchen sink.
Preparing for the Repair
Before starting the repair, you need to gather the necessary tools and materials and shut off the water supply.

Turn Off Water Supply
Before starting any repairs, it’s crucial to turn off the water supply to your faucet. To do this, follow these steps:
- Locate the water valves beneath the sink.

Disassembling the Faucet
Once the water supply is turned off and your tools and materials are gathered, you can start disassembling the faucet to access the damaged components. This process may seem daunting, but with the right tools and a bit of patience, you can easily disassemble your faucet and identify the source of the leak.
This section will guide you through removing the faucet handle and detaching the retaining nut and collar. By carefully disassembling the faucet, you’ll be able to inspect the cartridge, O-rings, and seals for damage and replace them as needed.
Remove the Faucet Handle
The first step in disassembling your faucet is to remove the faucet handle. To do this, follow these steps:

This section will guide you through turning on the water supply, running water through the faucet to check for leaks, and adjusting the handle position if necessary.
Turn On Water Supply
Begin by turning on the supply valves beneath the sink, rotating them clockwise to open the water valves and restore the water supply. Open the faucet to release any trapped air in the supply lines and allow water to flow through the faucet.
Run water through the faucet for approximately one minute to check for any leaks. If you notice any water seeping from the faucet, double-check your repair work to ensure that all components are properly seated and secured.
