Water Pressure Problems
Low, high, or inconsistent pressure — what's causing it
Overview
Water pressure problems can affect one fixture, one area, or the whole home. The cause determines the fix — from a clogged aerator to a failing pressure-regulating valve or a supply line issue outside the home.
Common warning signs
- Weak flow from kitchen or bathroom faucets
- Shower pressure noticeably weaker than before
- Pressure varies significantly throughout the day
- Air sputtering from faucets
- Pressure that seems too high — banging pipes, fixture wear
- Flow at one fixture fine, others weak
Possible causes
An on-site assessment is needed to confirm the cause in your specific situation. This list represents common possibilities, not a diagnosis.
- Clogged aerator or shower head (mineral deposits)
- Partially closed shut-off valve
- Failing or improperly set pressure-regulating valve (PRV)
- Scale buildup in older galvanized pipes
- Leak on the supply line reducing pressure
- Municipal supply pressure changes
What we inspect
- Pressure at the main supply entry point
- PRV condition and setting (if present)
- Fixture-specific flow and aerator condition
- Shut-off valve position throughout the home
- Visible pipe material and condition
Our process
Measure pressure at multiple points to isolate the location of the problem
Inspect PRV if present — condition, setting, and age
Check fixture-level components for blockage
Review shut-off valve positions
Recommend and implement the appropriate fix after estimate approval
Factors that may affect cost
We provide written estimates before any work begins. The following factors may affect the scope and cost.
- Whether the issue is a simple fixture cleaning or a PRV replacement
- Pipe material — galvanized pipe may require section replacement if scaled internally
- Supply line access if the issue is at the entry point
