CALIFORNIA - PLUMBING GUIDE
Low water pressure help in California
A weak shower or slow-filling sink is frustrating. Start by separating a one-fixture problem from a whole-home pressure change.

One fixture or the whole home?
If only one faucet is affected, a clogged aerator may be involved. If several fixtures are weak, tell the plumber whether the change was sudden, gradual or followed recent plumbing work.
A useful first check
Note which fixtures are affected and whether hot and cold water behave differently. Check for visible drips or wet areas without opening walls.
Leave regulator adjustments to a professional
Turning a pressure regulator without measuring pressure can leave it too high or too low. Ask for a diagnosis before agreeing to a regulator replacement.
Questions before you call
Does weak pressure always mean a leak?
No. Valves, aerators, regulators and supply issues can all be involved. A professional diagnosis helps distinguish them.
What should I say when I call?
Describe the fixtures affected, when the problem began and any recent plumbing or water-softener work.
