A drip under the sink and a pipe spraying inside a wall are both leaks, but only one is an emergency. Knowing the difference saves money and damage. This guide gives you 7 signs that mean call now, a list of leaks that can usually wait until morning, and the first steps to take. Our line is answered 24/7 at (951) 299-3473.

For urgent hidden leaks, our leak detection Murrieta CA team handles emergency calls first.

How do I know if a water leak is an emergency?

A water leak is an emergency when water is flowing fast, spreading to floors, ceilings or electrical areas, or coming from a line you can't shut off. It is also urgent when you hear water running with every tap off, see a warm wet spot on a slab floor, or find sewage. In these cases, shut off the main valve and call right away.

What are the 7 signs to call right away?

  1. Water spraying or pouring from a pipe, fitting or appliance line.
  2. Water near outlets, panels or light fixtures. Turn off power to the area at the breaker if you can do it safely.
  3. A bulging or dripping ceiling. Water is pooling above and the drywall can fall.
  4. The sound of running water inside walls or under the floor when everything is off.
  5. A hot, wet patch on the floor. This often means a hot water line is leaking under the slab.
  6. Sewage backing up into tubs, showers or floor drains.
  7. A leak you can't stop because the shut-off valve is stuck or missing.

If you smell rotten eggs or hear hissing near a gas line, that is a gas emergency, not a water one. Leave the home, then call 911 and SoCalGas from outside. Our gas leak Murrieta CA page explains what happens next.

Which leaks can usually wait until morning?

Slow leaks you can contain can usually wait for a daytime visit. That includes a dripping faucet, a toilet that runs, a slow drip under a sink caught in a bucket, a damp spot that isn't spreading, and a higher-than-normal water bill with no visible water. Turn off the local valve if there is one, and call during the day.

  • A faucet or shower head that drips.
  • A toilet that runs or refills on its own.
  • A slow drip under a sink with the angle stop closed.
  • A small stain that stays the same size.
  • A high water bill. See high water bill for what to check first.

What should I do first in a water emergency?

Shut off the main water valve first. In most Murrieta homes it is near the front hose bib, in the garage, or at the meter box by the curb. Then turn off the water heater, cut power to wet areas if safe, move valuables, and take photos for insurance. Call us once the water is stopped, so we can find the source.

Our step-by-step guide on how to shut off your water in an emergency shows where the valve usually is. Older homes in Historic Murrieta may have the valve in a different spot than newer tract homes in Bear Creek or Los Alamos Hills.

What does emergency leak detection cost?

Emergency visits use the same tools and prices as daytime visits, with the price confirmed before a tech is sent. Standard water leak detection in Murrieta usually costs about $200 to $550, and slab leak detection about $250 to $650. Repairs start around $300. A fast call often costs less overall, because water damage grows by the hour.

If the leak is under the floor, our slab leak detection Murrieta CA service finds it with little demolition. Our slab leak repair Murrieta crew can then fix it, and the leaking pipe repair guide explains the choices.

How can I lower the risk of a leak emergency?

  • Know where your main valve is and make sure it turns.
  • Replace rubber washer and sink hoses with braided steel.
  • Install a pressure regulator if your pressure is over 80 psi; see high water pressure leaks.
  • Add smart water leak detectors near the water heater and washer.
  • Run a meter test every few months.

Frequently asked questions

Should I call a plumber or leak detection company in an emergency?

If you can see the broken pipe, a plumber can fix it. If water is coming from inside a wall, ceiling or slab, leak detection finds the exact source first.

Is a slab leak an emergency?

A hot water slab leak with a warm, wet floor is urgent. Shut off the water heater and call. A slow cold-water slab leak should still be checked within a day or two.

Can I wait until morning for a leak?

If you can stop the water with a local valve and nothing is spreading, usually yes. If not, shut off the main and call now.

Do you charge more for nights and weekends?

You get the price before a technician is sent, any time of day.

Prices are approximate estimates for planning. Your final price depends on your property and is confirmed before work begins.
