Common Low Water Pressure Scenarios
Check if It's One Fixture or Whole House
Low pressure at one faucet is usually a clogged aerator or shut valve. Whole-house low pressure points to the main supply line, pressure regulator, or municipal issue.
Check the Pressure Regulator
Homes with a pressure regulator (bell-shaped valve near the main shutoff) can lose pressure when the regulator fails. Replacement costs $200-$400.
Look for Leaks
A significant leak in your supply line drops pressure throughout the house. Check your water meter with all fixtures off — if it's spinning, you have a leak.
Check Municipal Notices
Your water utility may be doing maintenance. Check their website or call before hiring a plumber for a temporary municipal issue.
Frequently Asked Questions
What causes low water pressure?
Common causes: clogged aerators, partially closed shutoff valves, a failing pressure regulator, corroded galvanized pipes restricting flow, leaks in the supply line, or municipal water main issues. In Concord homes with galvanized pipes, internal corrosion is a frequent culprit.
How do I fix low water pressure in my Concord home?
Start simple: clean faucet aerators, check shutoff valves are fully open. If the problem is house-wide, test your water pressure with a gauge (should be 40-60 PSI). Below 40 PSI, call a plumber to check the pressure regulator and main supply line.
How much does it cost to fix low water pressure?
Causes and costs: aerator cleaning (free DIY), pressure regulator replacement $200-$400, main water line repair $1,500-$5,000, whole-house repipe $4,000-$15,000. A plumber's diagnostic visit ($100-$200) identifies the cause before you commit to expensive repairs.
Can old pipes cause low water pressure?
Yes — galvanized steel pipes (common in homes built before 1960) corrode internally, narrowing the pipe and restricting water flow. If your Concord home has original galvanized pipes and low pressure throughout, repiping to PEX or copper is the permanent fix.
