Why is my water pressure so low?
If it's one fixture, clean the aerator. If it's the whole house, check that the main valve is fully open, and check with your water utility for area issues. For persistent house-wide low pressure, the cause is usually corroded pipes, a failing pressure regulator, or a hidden leak.
How do I check my water pressure?
Attach a pressure gauge ($10 from any hardware store) to an outdoor hose bib. Normal residential pressure is 40–60 PSI. Below 40 PSI indicates a problem. Above 80 PSI is too high and requires a pressure regulator to prevent pipe damage.
