Plumbing emergency steps
- 1
Shut off the main water
Find the meter box at the curb (use a meter key, turn the valve a quarter turn) or the house valve where the line enters — often near the hose bib or garage. Turn clockwise until it stops.
- 2
Water heater shutoff
Close the cold-water valve on top of the heater. For gas, turn the control knob to OFF or PILOT; for electric, switch off its breaker.
- 3
Smell gas? Leave now
Do not flip switches, light anything, or use your phone inside. Get everyone out, then call the gas company or 911 from outside.
- 4
Sewage backup
Stop using all water and drains. Keep people and pets away; sewage carries bacteria. Do not touch it without gloves.
- 5
Photograph for insurance
Take wide and close photos and video of the water source, damage, ceilings, floors, and belongings before cleanup. Keep receipts.

What after-hours service should cost
In California, an emergency call-out commonly runs $250–$900 before repairs. Ask for the trip fee and hourly rate before work starts. A price far above that range, or refusal to put it in writing, is a red flag.

Renters: your landlord's duty
Under California Civil Code §1941.1, landlords must keep plumbing, hot and cold water, and sewage disposal in working order. Notify your landlord in writing (email or letter), keep a copy, and describe the problem and date.
