Faucet making noise but no water: causes, part cost
Prices checked 2026-08-28
A faucet making noise but no water is most often a loose washer or worn cartridge problem - about 34% of reported jobs. Here is how to confirm it, what the part costs, and when to stop.
A faucet is a valve in a pretty shell. Drips and weak flow are the two faults that matter, and both are usually a worn cartridge or O-ring – a few dollars in parts.
Faucet making noise but no water is one of the most common repair searches there is. Noises are the machine narrating its own failure. A rattle, a squeal and a hum each point at different parts, and the sound usually tells you which one – which is why this list is organised by what you hear.
Before you call anyone: 30-second checks
- Identify the sound first: squealing is usually a belt or bearing, grinding a bearing or foreign object, humming a motor or capacitor.
- Check for foreign objects – a coin, bone or zipper explains a surprising share of noises.
- Check that the unit is level and not vibrating against a wall or panel.
The likely causes, ranked
Loose washer or worn cartridge
About 34% of faucet making noise but no water jobs come back to this cause. Gaskets, seals and pans wear out on a schedule and leak only when the unit is running or full – which is why the leak is so often found after the machine has been used.
How to confirm it: Dry the area, run the unit, and watch for the first drop; a leak at a seam or gasket line points at that seal.
Typical fix: $20. A capable DIYer can usually handle this one. You would be looking for a faucet cartridge.
Water hammer in the pipes
About 30% of faucet making noise but no water jobs come back to this cause. This is a component-level failure – the part itself has worn out or failed, which is why it sits on the ranked list rather than the free-check list.
How to confirm it: It is worth confirming with a multimeter or a visual check before ordering the part, and worth asking the shop if the part is returnable.
Typical fix: usually free. A capable DIYer can usually handle this one.
Aerator debris / restricted flow
About 20% of faucet making noise but no water jobs come back to this cause. Restricted airflow or a blocked path is the most common and cheapest cause in this whole list – the unit cannot breathe, so it cannot do its job.
How to confirm it: Check the filter, vent or hose run for build-up and restriction; cleaning it is free, and it is the first thing to rule out.
Typical fix: usually free. A capable DIYer can usually handle this one.
Supply valve partially closed
About 16% of faucet making noise but no water jobs come back to this cause. The gas or fuel side – supply, valve, regulator, carburettor – is where fuel stops flowing, and it is a licensed-work zone when gas is involved.
How to confirm it: Check the supply is on and the line is clear; for fuel units, check the fuel age and the carburettor if it has sat unused.
Typical fix: usually free. A capable DIYer can usually handle this one.
When to stop and call a pro
A loud bang, a screech that changes pitch, or any noise followed by a smell – stop the unit and investigate. Otherwise, identify the sound, find it on the list, and price the part before calling anyone.
How to keep it from coming back
Noise is wear announcing itself early. Catching a bearing or belt at the squeal stage costs $20-60; catching it at the failure stage costs a motor or a drum.
Bottom line: Faucet making noise but no water is worth diagnosing before you call anyone – the free checks above catch a surprising share of cases, and the ranked list tells you what the part should cost if it is not one of them. Run the figures through the repair-or-replace test on this page before you authorise any work, and never pay for a diagnosis without getting the part name and the price in writing first.

Frequencies are the share of reported jobs attributed to each cause across repair-platform and forum data - a starting point for diagnosis, not a certainty.
What this should cost to put right
Across the causes listed above the repair runs $0 to $20. A quote far above the top of that range is usually a diagnosis of convenience - get a second opinion before you authorise it.
Repair it, or replace the unit?
This is the number people get wrong most often, and it costs them the most. Run the quote through the test - it uses the mid-point cost of the fix above against a new unit and the years this one has left.
REPAIR IT
The repair is 1% of a new unit and the appliance has roughly 6 year(s) of expected life left. Fixing it is the economical call. A new unit would save about $45/year in running costs, so keep repairing until that pays back in under 5 years.
Decision rule: repair when the fix costs under 50% of a replacement and the unit is under 70% through its expected life.

Common questions
Is it dangerous if my faucet has a "making noise but no water" problem?
Usually not immediately - none of the likely causes on this page involve gas, fuel or a mains electrical fault. The two cautions that apply everywhere: keep water away from any electrical point, and if you ever smell gas or burning, stop diagnosing and call a professional.
How much does it cost to fix a faucet with a "making noise but no water" problem?
Most fixes for this run $0 to $20. The most common cause, loose washer or worn cartridge, runs about $20 to put right, and the part you would be looking for is faucet cartridge. Get the diagnosis in writing before authorising anything above the top of the range.
Why does my faucet have a "making noise but no water" problem?
In about 34% of reported cases it is a loose washer or worn cartridge. It is the first thing to check because it is the most common - and usually the cheapest. If that checks out clean, work down the ranked list on this page before paying for a diagnosis.
Should I repair or replace my faucet?
Repair it when the fix costs under half of a replacement and the unit is under 35% through its roughly 15-year expected life. Past that point a repair is usually a deposit on the next failure - run the test on this page with your actual quote before you decide.
