Why is my water pressure suddenly low?
Sudden low water pressure is often caused by a clogged aerator, a partially closed shutoff valve, or a pressure regulator issue. Start by cleaning the aerators on your faucets. Then check that the main shutoff valve near your water meter is fully open. If only one fixture is affected, the problem is local. If the whole house has low pressure, you may have a pressure regulator issue or a main line leak that requires a plumber.
Why It Matters
Sudden low pressure can indicate a serious problem like a leak or failing pressure regulator. Addressing it early prevents further damage.
