What to Do Before the Plumber Arrives for a Burst Pipe

A burst pipe releases a genuinely large volume of water quickly once municipal pressure is behind it, and the damage a burst pipe causes is determined far more by how long the water runs than by the size of the crack itself. That's why the single most important thing you can do isn't waiting for a plumber, it's stopping the water immediately.

Find your home's main water shutoff valve and turn it fully off. In most Folsom homes, this valve is located where the water line enters the house, often in a garage, a utility closet, or along an exterior wall, or at the meter box near the street if the interior valve is hard to locate or access. Turning this valve clockwise (righty-tighty) shuts off water to the entire house, which stops the burst pipe from continuing to flow regardless of where in the house it's located.

If you're not sure where your shutoff valve is, this is worth figuring out now, before an emergency, rather than during one. Walk through your home and locate it, and consider labeling it clearly so anyone in the household can find it quickly under stress. If you're mid-emergency right now and can't locate it, call us immediately, we can walk you through finding it over the phone while help is on the way.

Once the water is off, turn off electricity to any area where water is pooling near outlets, switches, or a breaker panel, but only if you can do so safely without stepping into standing water yourself. If reaching the breaker panel means walking through water, don't risk it, wait for help rather than risking an electrical hazard.

With the water and any relevant electricity addressed, move furniture, rugs, electronics, and valuables away from the affected area if it's safe and quick to do so. Standing water damages materials faster than most people expect, a rug or piece of furniture left sitting in water for even 20 to 30 minutes can be much harder to salvage than one moved immediately.

Take a few photos of the damage before cleanup begins, even quick ones on your phone. This matters for insurance purposes and costs almost nothing in the moment. Then call us. Tell us the water is off and give us a clear sense of where the burst occurred and how much water is involved, that information helps us prioritize dispatch and bring the right equipment on the first trip rather than a second visit.

If water has already spread beyond what a towel or wet-vac can reasonably handle before we arrive, don't spend excessive time trying to manage it yourself. Prioritized in order: water off, electrical safety, valuables moved if safe, photos taken, then call. Everything else, the actual drying and repair, is what we handle once we're there.

A question we hear often afterward is whether it's safe to run a household fan or dehumidifier while waiting for us to arrive. It's generally fine and can help marginally with surface moisture, but don't expect it to meaningfully dry out flooring or drywall on its own, standard household equipment isn't built for that scale of water intrusion. If the burst happened in a room with electronics or sensitive equipment nearby, moving those items takes priority over trying to run a fan in the same space.

If the burst pipe is on an exterior wall or in an area exposed to the outdoors, an outdoor hose bib or a line running through an uninsulated garage, for example, note that detail when you call. It sometimes points to a different underlying cause, occasional cold-snap freezing rather than the more common pressure-surge failure we see on interior lines, and knowing that in advance helps us bring the right approach for the specific type of failure.

Once we've arrived and the immediate water and safety concerns are handled, we'll assess whether the burst was an isolated event or a sign of a broader issue with aging pipe elsewhere in the home. If your home has original galvanized supply lines, one burst is sometimes an early warning that the rest of the system is approaching the end of its service life, and we'll flag that honestly rather than just patching the immediate break and leaving the bigger question unaddressed.

It's also worth preparing a small emergency kit in advance rather than scrambling during the actual event: a flashlight kept somewhere accessible in case a breaker needs to be checked in a dim utility area, a few old towels set aside specifically for water emergencies rather than mixed in with regular linens, and our number saved in your phone rather than searched for under stress. None of this prevents a burst pipe from happening, but it shaves valuable minutes off your response time when it does, and those minutes are exactly what determines how much real damage occurs before help actually arrives. A little preparation now genuinely pays off the one time in your life you actually need it most of all.
