Introduction
At Dovis Plumbing, one of the most common calls we get is about low water pressure in one faucet. But if it’s just one faucet and not the whole house, the problem is usually isolated and often easier to fix than you think.
Common Causes of Low Water Pressure in One Faucet
- Clogged Aerator – Over time, mineral buildup or debris can block the tiny holes in your faucet’s aerator, reducing water flow.
- Partially Closed Shut-Off Valve – Each sink or fixture has its own shut-off valve. If it isn’t fully open, you’ll notice weak pressure.
- Mineral or Sediment Buildup – Hard water deposits inside faucet components or connecting pipes can restrict flow.
- Worn-Out Cartridge (in Single-Handle Faucets) – A failing cartridge can limit both hot and cold water flow.
Quick Fixes You Can Try for Low Water Pressure in One Faucet
- Unscrew the faucet aerator, clean out debris, and reinstall.
- Check the shut-off valve under the sink and make sure it’s fully open.
- Soak faucet parts in vinegar to dissolve mineral buildup.
- For cartridge faucets, consider replacing the cartridge.
When the Problem with Low Water Pressure in One Faucet Runs Deeper
If DIY fixes don’t solve the issue, the cause might be:
- A hidden leak in the supply line feeding that faucet.
- A failing pressure regulator (affecting certain lines).
- Corroded pipes restricting flow.
In these cases, it’s best to call a licensed plumber. Ignoring low pressure could mean bigger plumbing problems down the road.
