Burst and Leaking Pipe Repair in Gardena, CA

Pipe burst? Do this first

Short answer: close the main water shutoff, keep away from water near outlets or the electrical panel, move belongings out of the way and take photos. Then call for a repair. The faster the water is off, the less damage there is to dry out later.

1. Close the main shutoff valve. On many Gardena houses it's on the outside wall where the water line enters, often near a front hose bib. Turn it clockwise until it stops.
2. Open a faucet at the lowest point of the house to drain the remaining pressure.
3. Stay clear of electricity. If water is near outlets, fixtures or the panel, don't walk through it.
4. Turn off the water heater if the water will be off for a while.
5. Document the damage with photos or video for the provider and any insurance claim.

If the water is coming from the yard or the street instead of inside the house, see main water line break: what to do first.

Signs of a hidden pipe leak

• Water stains, bubbling paint or sagging spots on a ceiling or wall.
• Damp cabinet floors under sinks, or a musty smell.
• Warped flooring or loose tiles.
• The sound of running water when nothing is on.
• A water meter that keeps moving with all fixtures off. See how to check your meter.
• A higher water bill without a change in use.

Warm spots on a concrete floor point to a leak under the slab. See slab leak detection and repair.

Why pipes burst or leak in Gardena homes

• Corrosion in older pipe. Galvanized steel in mid-century homes rusts from the inside, and older copper can develop pinhole leaks.
• High water pressure from a failing pressure reducing valve, which strains pipes and fittings.
• Failed connectors to toilets, faucets, dishwashers and washing machines.
• Water hammer, the bang when a valve closes quickly, which stresses joints over time.
• Physical damage during remodeling, or pipes shifting after ground movement.

Freezing, a common cause in colder states, is rare in Gardena's mild climate.

Repair options

• Section repair. The damaged piece of pipe is cut out and replaced. Common for a single burst or leak.
• Connector or valve replacement when the leak is at a supply line or shutoff.
• Reroute. A new line is run around a hard-to-reach or failing section.
• Repipe. When leaks keep happening, replacing more of the plumbing may be more practical. See whole-house repiping.

Drywall, ceiling and flooring repairs are often separate from the plumbing repair. Ask what is included.

Questions to ask before work starts

• What caused the leak, and are other sections at risk?
• Is this a temporary fix tonight or a permanent repair?
• Is there an after-hours charge, and what is included in the price?
• Who handles wall or ceiling repair and drying?
• What is your California contractor license number? Check it with the Contractors State License Board.
