Low water pressure can be a small fixture problem or a sign of a larger plumbing issue. The first useful question is whether the pressure is low at one faucet, one area of the house or everywhere.
Low pressure at one fixture
A clogged aerator, showerhead or local valve is a common cause. Mineral buildup can restrict flow even when the rest of the home works normally.
Low pressure throughout the house
If every fixture is affected, check that the main shutoff valve is fully open. A pressure-reducing valve, supply issue or restriction in the home’s piping may also be involved.
Could a leak reduce water pressure?
A significant leak can affect pressure, particularly if it is on a main branch or service line. Look for unexpected water use, damp areas or meter movement when fixtures are off.
When to call a plumber
If the change was sudden, affects the whole house, or comes with visible leakage, unusual pipe noise or discoloured water, professional diagnosis is appropriate. Testing the system is safer than replacing parts at random.
