Low water pressure
Weak flow from one faucet or the whole house.
What you're probably seeing
Weak flow from one faucet or the whole house.
Likely causes
- Clogged faucet aerators or shower heads (one fixture).
- A partly closed or failing main valve or pressure regulator.
- Corroded old pipes, or a hidden leak.
Safe checks you can do now
- Unscrew and clean the aerator on the weak faucet.
- Make sure the main shutoff is fully open.
- Ask neighbors if they have low pressure too (a utility issue).
When to call a pro
Pressure is low everywhere and the main valve is open, or it dropped suddenly.
