Is it the house or the street?

  1. Check every fixture.Try a kitchen faucet, a bathroom faucet and an outside hose bib. If only one fixture is weak, the problem is local to it.
  2. Ask a neighbor.If neighbors have no water too, the issue is likely with the water system, not your plumbing.
  3. Check with your provider.Look for outage or main break notices from your water provider. Depending on the address, that may be the City of Brea's utility or another provider.
  4. Check your valves.Make sure the house main and the meter valve are fully open, especially if anyone worked on the plumbing recently.
  5. Look for a leak.A sudden pressure drop with a running meter can mean a broken line somewhere on the property.

Causes and what they look like

CauseClue
Water system outage or main breakNeighbors affected, notice from the provider
Partly closed main or meter valveWhole house weak after recent work
Failed pressure regulatorPressure suddenly very low or very high throughout the house
Burst or slab leakMeter spinning, wet area, sound of running water
Corroded galvanized pipeGradual decline, worst at the farthest fixtures
Clogged aerator or cartridgeOnly one faucet or shower is weak

The galvanized pipe problem

Some older Brea homes still have galvanized steel supply lines. Over decades they rust from the inside, narrowing the opening until the farthest bathroom gets a trickle. This happens slowly, not overnight, and it often shows up as brown water after the lines sit unused.

When pressure loss is gradual and widespread in an older house, a licensed plumber may talk about replacing sections or repiping. That is a planned project, not an emergency, and it is worth getting the scope and options in writing.

What to do

  • IfThe whole street has no waterContact your water provider and wait for service to return. Keep a few faucets closed so sediment does not flood in at once.
  • IfOnly your house, with a spinning meterClose the house main and call a licensed plumber about a possible leak.
  • IfOnly your house, no leak signsCheck valve positions and the pressure regulator, then book a plumber.
  • IfOne fixture onlyClean the aerator or shower head, then schedule a fixture repair if needed.

Questions to ask a plumber

  1. Can you measure my static water pressure?
  2. Is my pressure regulator working, and is it near the end of its life?
  3. Is the low pressure from pipe corrosion, a leak or a valve?
  4. If it is the pipes, what would partial or full repiping involve?
  5. What is your CSLB license number?

Common questions

Why is my water brown after it came back on?
After an outage, sediment can be stirred up. Run a cold faucet until it clears. If it stays discolored, contact your provider.
Can high pressure be a problem too?
Yes. Pressure that is too high can stress pipes and appliances. A licensed plumber can test it and check the regulator.
Should I turn off the water heater during an outage?
If the outage is long, setting the heater to vacation or pilot mode is a reasonable precaution.
