Emergency Plumber: What to Do Before We Arrive
Water doesn't wait for business hours. If a pipe has burst or a leak is spreading, these five steps protect your home — and your wallet.
Every week we get the same call: a homeowner finds water where it shouldn't be, panics, and doesn't know whether to call a plumber, turn off the water, or do both. The good news is that the first five minutes make most of the difference. Here's exactly what to do.
1. Shut off the water — but know which valve
The main shutoff valve is usually where the water line enters the house: basement, crawlspace, or garage. Turn it clockwise until it stops. If the leak is only at one fixture — a toilet, a sink — close the small valve at the wall behind it instead, so the rest of the house keeps water.
2. Turn off the water heater
If the leak is on the hot side or you're shutting the main line, flip the water heater's power or gas off. An empty tank that keeps heating is a fire and warranty risk.
3. Open a cold faucet
Opening the highest and lowest cold faucets in the house drains the lines and relieves pressure. Less pressure means less water finds its way out while you wait.
4. Move what matters
Electronics, documents, and anything in cardboard off the floor near the leak. Photos of the damage before cleanup also help with your insurance claim — take them now, while it's visible.
5. Call a licensed emergency plumber — with the right info
When you call, know three things: where the water is coming from, whether you shut off the main, and your street. That gets us to you faster with the right parts on the truck.
DIY vs. emergency call: the honest breakdown
| Situation | DIY or call? | Why |
|---|---|---|
| Slow drip at a faucet | DIY (washer or cartridge) | $5 part, 20 minutes, no risk |
| Running toilet | DIY (flapper) | Common $8 fix |
| Clogged drain, single sink | DIY (plunger or snake) | Try before you pay |
| Burst pipe or active leak | Call 24/7 now | Every minute of delay raises the damage |
| Backed-up sewer line | Call a pro | Needs camera + equipment, not a plunger |
| Water heater leaking from the tank | Call a pro | Tank is done; replacement needed |
How much does an emergency plumber cost?
Emergency dispatch typically runs higher than a scheduled visit because it pulls a tech off the regular route. Most homeowners pay between $150 and $450 for an after-hours call, parts and the fix on top. The cost of NOT shutting off the water is almost always worse — a slow leak left running overnight can do thousands in damage.
Prevent the next emergency
Most emergency calls we run are avoidable: aging supply lines, unmaintained water heaters, and tree roots in the main line. If you want fewer surprises, read our guide on keeping your water heater healthy — or book a routine inspection and we'll flag the weak points before they fail.
