Low Water Pressure Repair
Quick answer
Check one fixture against the whole house first. One weak tap is usually a clogged aerator or showerhead you can clean. Low pressure everywhere, with normal pressure at the neighbors, is a plumber's job: a failed pressure-reducing valve, corroded pipe or a hidden leak. Call (888) 217-6781 for a plumber in your ZIP.
Follow the short menu, then your 5-digit ZIP. The line goes quiet for a few seconds while it connects; stay on. If it does not connect, call once more: companies taking calls change minute to minute.
Signs you need a plumber
- Weak flow at every tap and shower
- Pressure that drops when a second fixture runs
- One faucet or showerhead noticeably weaker than the rest
- Pressure that changed suddenly
A sudden drop in pressure together with the meter moving while everything is off can mean a broken line. Close the main shutoff and call.
What to check before you call
- Unscrew and rinse the aerator or showerhead on the weak fixture
- Ask a neighbor whether their pressure is normal
- Make sure the main shutoff valve is fully open
- Watch the meter with everything off to rule out a leak
What the plumber does
- 1
Measures the pressure
Puts a gauge on a hose bib to see what the house is actually getting.
- 2
Checks the regulator and valves
Tests or replaces the pressure-reducing valve and checks the main and fixture valves.
- 3
Looks at the pipe
Old galvanized pipe that has corroded inside, or a leak, may need a section replaced.

Step-by-step guides
Low water pressure: common questions
Why did my water pressure suddenly drop?
A sudden drop across the house points to the pressure-reducing valve, a partly closed main valve, a leak, or work on the city main. Ask a neighbor first: if theirs is low too, call the water utility.
Can low water pressure be fixed?
Usually. A clogged aerator is a two-minute fix; a regulator is a common plumber repair; corroded pipe takes a repipe of the affected section.
