If your sink suddenly has weak water pressure or your faucet is barely flowing, don’t panic — and don’t assume you need a major plumbing repair right away. In many cases, a low flow faucet is caused by something simple: sediment buildup inside the faucet aerator.
At Danco Plumbing Services, we help homeowners across York County, SC and surrounding areas troubleshoot plumbing problems every day. Before scheduling a service call, there are a few quick things you can safely check yourself that may restore your faucet flow in just a few minutes.
To help homeowners out, Travis from Danco Plumbing Services put together this quick video walkthrough showing exactly what to inspect and clean when dealing with a low flow faucet.
Watch: Quick DIY Fix for a Low Flow Faucet
In the video above, Travis from Danco Plumbing Services demonstrates the same troubleshooting process our technicians use when diagnosing faucet flow issues in customers’ homes throughout York County, SC.
What Causes a Low Flow Faucet?
A faucet that suddenly loses pressure is usually a sign that water flow is being restricted somewhere near the fixture itself. One of the most common culprits is sediment trapped inside the faucet aerator. This issue is especially common in homes with well water, where naturally occurring sediment can accumulate inside faucet aerators over time.
This issue is especially common in homes with:
- Well water systems
- Older plumbing pipes
- Recent plumbing repairs or water shutoffs
- Mineral-heavy water
- Sediment stirred up from municipal water work
Over time, small particles can collect inside the faucet screen and reduce the amount of water that can pass through.
The good news? Cleaning the aerator is often fast, easy, and inexpensive.
What Is a Faucet Aerator?
The aerator is the small screen attachment located at the tip of your faucet spout. Its job is to:
- Control water flow
- Reduce splashing
- Improve water efficiency
- Filter small debris particles
When sediment builds up inside this screen, your faucet pressure can drop significantly.
How to Fix a Low Flow Faucet
In the video above, Travis walks through the exact process Danco Plumbing Services recommends homeowners check before scheduling plumbing service.
Step 1: Remove the Aerator
Many modern faucets use a special aerator key to remove the aerator safely without damaging the fixture. These keys are often included with the faucet when it is installed. Using the proper tool helps prevent damage to the finish and makes removal much easier.
Once removed, you’ll usually find:
- A washer
- A screen filter
- Small debris or sediment buildup
Step 2: Clean the Screen
Rinse the screen thoroughly and remove any visible debris. Mineral deposits, sand, rust flakes, and sediment commonly get trapped here. Hold the screen under running water to flush out trapped sediment, sand, and mineral deposits before reinstalling it.
For stubborn buildup, soaking the aerator in vinegar can help break down mineral deposits.
Step 3: Reassemble the Faucet
Once cleaned:
- Replace the washer
- Reinsert the screen
- Tighten the aerator back into place
In many cases, this immediately restores proper water pressure.
Why This Happens More Often With Well Water
Homes on well water frequently experience sediment-related plumbing issues because groundwater naturally contains minerals and particles that can travel through the plumbing system.
At Danco Plumbing Services, we regularly help homeowners with:
- Sediment buildup
- Hard water issues
- Faucet flow problems
- Water filtration upgrades
- Well system plumbing concerns
If your faucet aerators continue clogging repeatedly, it may be a sign of a larger water quality issue worth addressing.
When a Low Flow Faucet Means a Bigger Problem
While aerator buildup is common, sometimes low water pressure points to a larger plumbing issue.
You may need professional plumbing service if:
- Multiple faucets have low pressure
- Hot water pressure is weaker than cold
- Water pressure drops throughout the house
- The issue keeps returning
- You notice pipe leaks or corrosion
- Water is discolored
- Faucets sputter or spit air
These symptoms could indicate:
- Pipe corrosion
- Pressure regulator issues
- Hidden leaks
- Water line restrictions
- Water heater sediment buildup
That’s where an experienced licensed plumber can help properly diagnose the issue.

Frequently Asked Questions About Low Flow Faucets
Why does only one faucet in my house have low pressure?
If only one fixture is affected, the issue is often isolated to the faucet aerator, supply lines, or shutoff valve for that fixture.
Can hard water cause a low flow faucet?
Yes. Hard water minerals commonly build up inside faucet aerators and plumbing fixtures, reducing water flow over time.
Is it safe to clean a faucet aerator myself?
In most cases, yes. Cleaning a faucet aerator is a simple homeowner maintenance task as long as you avoid over-tightening or damaging the fixture.
How often should faucet aerators be cleaned?
Homes with hard water or well water may benefit from cleaning faucet aerators every few months.
When should I call a plumber for low water pressure?
You should contact a plumber if multiple fixtures are affected, pressure continues dropping, or cleaning the aerator doesn’t solve the issue.
