Emergency Water Leak
Active water leak in your home causing flooding or water damage.
Emergency Water Leak: For an emergency water leak, immediately shut off the main water valve, usually located near the water meter or where the supply line enters your home. Then call a licensed plumber. Emergency plumbing costs $150–$500+ depending on severity. Acting quickly prevents thousands in water damage to floors, walls, and foundations.
What Causes This?
Burst Pipe
Corroded, frozen, or high-pressure pipes can burst suddenly. Older galvanized pipes in pre-1970s homes are especially vulnerable.
Failed Water Heater
A corroded tank, failed pressure relief valve, or loose connections can cause flooding. Water heaters over 10 years old are at higher risk.
Broken Supply Line
Flexible supply lines to toilets, sinks, and washing machines can fail, causing continuous water flow. Common in aging supply lines with braided stainless covers.
Slab Leak
Leaks in pipes running beneath the concrete slab foundation. Common in Sacramento homes built on expansive clay soil. Signs include warm spots on floors and unexplained water bills.
Fixture Failure
A cracked toilet tank, broken faucet valve, or failed shower cartridge can cause significant water loss.
Can It Wait?
A water leak is one of the most urgent home emergencies. Every minute of delay means more water damage. Shut off the main water valve immediately and call for emergency service.

Repair vs. Replace
Repair
Repair if: the leak is isolated to one spot, the pipe material is sound, and the home's plumbing is generally in good condition.
Replace
Replace (repipe) if: the home has galvanized pipes, you've had multiple leaks, or the leak is in an inaccessible location. PEX repiping costs $4,000–$15,000 but prevents future leaks.
Rule of thumb: One leak is a repair. Multiple leaks in galvanized pipes means the whole system is deteriorating — repiping prevents repeated emergencies.
