Why Your Faucet Keeps Leaking and How to Fix It

Why a Leaking Faucet Should Not Be Ignored

A leaking faucet should not be ignored because even a slow drip can waste water and damage nearby surfaces over time. The sooner you handle the problem, the easier and less expensive the repair may be.

A steady drip can leave mineral stains in the sink, loosen parts inside the faucet, and create moisture around the cabinet below. In busy Tempe homes, especially kitchens that get used all day, a small leak can become a daily frustration.

A practical example is a faucet that drips only at night. That may seem harmless, but it can still point to pressure changes, worn seals, or a cartridge that no longer closes fully.

Common Faucet Drip Causes

Most faucet drip causes come from small internal parts that wear out with use. Washers, O-rings, cartridges, seals, and valve seats all help control water flow, and any damaged part can let water escape.

Common causes include:

Kitchen Faucet Issues That Often Lead to Leaks

Kitchen faucet issues often happen because kitchen sinks get heavy daily use. Handles, sprayers, hoses, and seals wear down faster when the faucet is used for cooking, cleaning, washing dishes, and filling containers.

Common kitchen faucet issues include leaks around the base, dripping from the spout, water under the sink, loose handles, and pull-down sprayer leaks. A pull-down sprayer may leak because of a loose hose connection, a worn washer, a cracked hose, or a damaged sprayer head.

Water under the sink needs quick attention. It may come from the faucet, supply lines, shutoff valves, or connections below the sink. If you see water pooling in the cabinet, stop using the faucet until the source is found.

How to Fix a Leaking Faucet Step by Step

You can fix some leaking faucets by replacing a worn washer, O-ring, cartridge, or seal. Before starting, make sure the water is off, and do not force rusted or stuck parts.

Follow these steps:

1. Turn off the hot and cold water supply valves under the sink.
2. Cover the drain so that screws and small parts do not fall in.
3. Identify the faucet type, such as compression, cartridge, ball, or ceramic disc.
4. Remove the handle carefully with the right tool.
5. Inspect the washer, O-ring, cartridge, seals, and visible buildup.
6. Replace damaged parts with exact matches.
7. Reassemble the faucet.
8. Turn the water on slowly and test for leaks.

Here is a simple example. A homeowner notices a steady kitchen faucet drip even when the handle is closed. After turning off the water and removing the handle, they find a worn cartridge. Replacing that cartridge may stop the leak.

Stop the repair if the shutoff valve leaks, parts are corroded, or the faucet still drips after replacement. That is when professional plumbing repair is the safer choice.

Repair or Replace: Which Option Makes Sense?

Faucet repair makes sense when the fixture is newer, the problem is limited to one worn part, and replacement parts are easy to find. Faucet replacement may be better when the fixture is old, corroded, loose, outdated, or keeps leaking after repairs.

For many Tempe homeowners, replacing an old faucet can also improve daily use. A new kitchen faucet may offer better water flow, a stronger sprayer, and fewer future leaks.

When to Call for Plumbing Repair

You should call for plumbing repair when the leak keeps coming back, water appears under the sink, the shutoff valves are stuck, or you are not sure what type of faucet you have. Calling a professional can prevent broken parts, water damage, and repeat repairs.

You should also get help if you see rust, heavy mineral buildup, damaged supply lines, or a leak that spreads into the cabinet. In Tempe and nearby East Valley homes, mineral buildup can make older faucet parts harder to remove without damage.

How to Prevent Future Faucet Leaks

You can prevent many faucet leaks by using fixtures gently and checking them regularly. Small maintenance habits can help washers, seals, cartridges, and supply lines last longer.

Use this quick checklist:

• Do not overtighten faucet handles.
• Clean mineral buildup around the base and aerator.
• Check under sinks for moisture once a month.
• Fix small drips early.
• Watch for loose handles or sprayer leaks.
• Replace aging faucets before they fail.

A simple habit is to look inside the cabinet when cleaning the kitchen or bathroom. If you notice moisture, stains, or a soft cabinet bottom, schedule a repair before the damage spreads.
