A shower that trickles or a faucet that can't fill a pot quickly is a daily frustration, but low water pressure is usually a symptom of something specific — a clogged aerator, a failing pressure regulator, corroded pipes, or a hidden leak. Guessing wastes money; diagnosing solves it.
We track down the real cause of low water pressure and fix it, whether it affects one fixture or the whole house.
Signs and patterns to notice
Where the low pressure shows up tells us a lot:
- One fixture weak (often a clogged aerator or valve)
- The whole house weak (regulator, main line, or corrosion)
- Only hot water weak (water heater or its connections)
- Pressure that's dropped gradually over years (buildup)
- Pressure that dropped suddenly (a possible leak or break)
What causes low pressure here
In older Westchester homes, corroded galvanized pipe narrowing from the inside is a leading cause of whole-house pressure loss. Others include a failing pressure regulator, mineral buildup from hard water, a partially closed valve, or a hidden leak bleeding off pressure. The pattern points us to the culprit.
What to do before you call
Check whether it's one fixture or many, and clean the aerator on a weak faucet — mineral buildup is a common, simple cause. Make sure the main and fixture shut-offs are fully open. If the whole house is weak or pressure dropped suddenly, that's worth a call.
How we fix it
We diagnose based on the pattern — testing pressure, checking the regulator, inspecting for corrosion or a leak. Then we fix the actual cause: clearing or replacing a fixture part, adjusting or replacing the regulator, or addressing corroded pipe. We restore proper flow rather than masking the symptom.
Sometimes weak flow is really a clogged efficient fixture — the EPA's how efficient fixtures affect flow information helps you tell good design from a real pressure problem.
When to call a pro
If cleaning aerators and checking valves doesn't restore pressure, or the whole house is affected, it's time to call — whole-house pressure loss usually means a regulator, corrosion, or leak that needs proper diagnosis.
Frequently asked questions
Why is only one faucet weak?
Usually a clogged aerator or a partly closed valve at that fixture — often a quick fix. Try cleaning the aerator first.
Why is my whole house low on pressure?
Common causes are a failing pressure regulator, corroded old pipe, or a hidden leak. The pattern helps us pinpoint it.
Can old pipes cause low pressure?
Yes. Galvanized pipe corrodes and narrows from the inside over decades, choking flow. It's common in older homes here.
Is low pressure a sign of a leak?
It can be, especially if it dropped suddenly. We check for leaks as part of diagnosing whole-house pressure loss.
Can you restore my original pressure?
Usually, once we fix the real cause — whether that's a part, the regulator, or a section of corroded pipe.
When corroded old pipe is the culprit throughout, the lasting fix is repiping to cure corrosion-choked flow rather than chasing pressure fixture by fixture.
