A pipe lets go at 11 p.m. and water is spreading across the kitchen floor. The instinct is to grab towels and start dialing — but the first five minutes matter more than how fast the plumber’s phone gets answered. Here’s the order of operations that actually limits the damage while you’re waiting to get connected, and what’s worth telling the plumber the moment you’re on the phone.

Step 1: Shut Off the Water — Know Where This Is Before You Need It

Every Austin home has a main shutoff, usually a valve near where the line enters the house (garage, utility closet, or exterior wall) or at the meter box near the curb. Turning it fully closed stops the flood at the source regardless of which fixture failed. If you don’t already know where yours is, this is worth finding today — not at 11 p.m. during an active leak. For a single fixture (a toilet or a washing machine hose, for example), the local shutoff under or behind that fixture is often faster than the main.

Step 2: Cut Power to Anywhere Water Is Spreading

If water is approaching an outlet, a power strip, or anywhere near the electrical panel, shut off the breaker for that area at the panel — from dry ground, never while standing in water. This isn’t optional if there’s any doubt; electricity and standing water is the one combination that turns a plumbing problem into a life-safety one.

Step 3: Contain and Protect, Don’t Try to Clean Yet

Towels and a wet-shop-vac or bucket at the leak point buy time. Move furniture, rugs, boxes, and anything electronic off the wet floor and away from the spread. Standing water left on wood flooring or under baseboards for hours, not minutes, is what turns a mop-up into a bigger repair — so containment now is worth more than a perfect cleanup later.

Step 4: Water Heater Emergencies Get a Different First Step

Leaking or failed water heater? Shut off the cold-water inlet valve at the top of the tank first — that stops the tank from refilling and overflowing. Then kill the gas valve or the breaker feeding the unit. A tank that’s actively leaking from the bottom seam usually means the tank itself has failed and needs replacement, not repair — useful to mention when you call.

Step 5: Photograph Before You Touch Anything Else

Once the water’s off and the area is safe, take photos and a short video of the standing water, the source if visible, and anything it touched — flooring, baseboards, cabinetry, belongings. This documentation is what an insurance adjuster or the plumber’s assessment will reference later, and it’s much harder to reconstruct after the cleanup starts.

When It’s Genuinely a “Call Right Now” Situation

Continuous flow you can’t stop at the main, sewage backing up into a tub or floor drain, or the smell of gas near a water heater (leave the house and call the gas utility or 911 first, plumbing second) all belong in the drop-everything category. A slow drip, a running toilet, or a fixture that’s merely annoying can usually wait for daytime dispatch without getting worse overnight.

What to Tell Dispatch When You Call

A fast, accurate description shortens everything downstream: what’s leaking (fixture, pipe, or water heater), whether you’ve already shut off the water, whether it’s still actively flowing, and roughly how long it’s been happening. That’s usually enough for the dispatch line to route you to a plumber who shows up with the right parts and gear already loaded.

Frequently asked questions

Where is the main water shutoff usually located in an Austin home? Most commonly near where the line enters the house — a garage wall, utility closet, or exterior hose-bib area — or at the meter box near the curb. It varies by builder and neighborhood, so it’s worth locating yours in advance.

Should I turn off electricity before dealing with a water leak? If water is anywhere near outlets, cords, or the electrical panel, yes — shut off the relevant breaker from dry ground. If there’s any doubt about safety, don’t enter the area at all until it’s confirmed safe.

Is it safe to use a shop vac on a flooded floor with the power still on? Only if the outlet you’re using and the flooded area are dry and separated from standing water. When in doubt, cut power to that circuit first.

How long can standing water sit before it causes real damage? Damage accelerates fast — wood flooring, drywall, and baseboards can start absorbing meaningful moisture within hours, not days. Contain and remove standing water as soon as it’s safe to do so.

Do I need photos before the plumber arrives, or can that wait? Take them as soon as it’s safe, before cleanup starts. Insurance and assessment both rely on documentation of the original scene, which is much harder to recreate later.

What counts as a true plumbing emergency versus something that can wait? Continuous uncontrolled flow, sewage backup, or a gas smell near a water heater are drop-everything situations. A slow drip or a running toilet is annoying but rarely urgent overnight.
