What to Do in a Plumbing Emergency Before the Plumber Arrives

Quick answer

In a plumbing emergency, your first move is to stop the water: close the shutoff valve at the affected fixture, or the home’s main shutoff if water is flooding or you can’t reach the fixture valve. Next, turn off the water heater if it’s involved, switch off electricity to any wet area at the breaker, and move valuables away from the water. Then call a plumber — and if you smell gas, leave the house first and call from outside.

1. Stop the water

Almost every plumbing emergency gets better the moment the water stops:

Find your main shutoff now, before you need it. In most Northern Virginia homes it’s where the water line enters the house — often in the basement, a utility closet, or near the water heater. Some homes also have a shutoff in a ground-level box outside near the street. Knowing where yours is can save you thousands in damage.

2. Turn off the water heater (if it’s involved)

If the emergency involves your water heater, or you’ve shut off the main, turn the heater off so it doesn’t run dry and damage itself. For an electric unit, switch off its breaker. For a gas unit, set the control to “pilot” or “off.”

3. Kill the power to wet areas

Water and electricity are a dangerous mix. If water is near outlets, appliances, or a breaker panel, switch off electricity to that area at the breaker — but only if you can reach the panel without standing in water. If you can’t do it safely, stay clear and tell the plumber when they arrive.

4. Contain and limit the damage

5. Relieve pressure

After shutting the main, open a faucet at the lowest point in the house (like a basement or outdoor spigot) to drain the remaining water in the lines and relieve pressure. This reduces how much water keeps coming from a break upstairs.

6. Call your plumber — and when to leave first

Once the water is off and the area is safe, call us. We answer 24/7 and will walk you through anything you’re unsure about. One exception: if you smell gas near a gas water heater or appliance, don’t flip switches or look for the source — leave the house, then call the gas company and us from outside.

One less worry: no surprise pricing

A plumbing emergency is stressful enough without wondering what the bill will be. An after-hours visit includes a call-out fee to come out and diagnose — which differs from a standard daytime visit — and the repair itself is quoted upfront. So you’ll know the full price before any work begins and can focus on protecting your home.

Frequently asked questions

Where is my main water shutoff valve?

In most Northern Virginia homes, the main shutoff is where the water line enters the house — commonly in the basement, a utility closet, or near the water heater. Some homes also have a shutoff in a ground-level box outside near the street. It’s worth locating yours before an emergency.

Should I turn off the electricity in a flood?

Yes, if water is near outlets, appliances, or the panel — switch off power to that area at the breaker. But only do it if you can reach the panel without standing in water. If you can’t do it safely, stay clear and tell the plumber when they arrive.

What should I do if I smell gas?

Leave the house immediately. Don’t flip any switches, light anything, or search for the source. Once you’re outside, call your gas company and a plumber. Treat a gas smell near a gas water heater or appliance as an emergency.

How much does an after-hours emergency call cost?

An after-hours or emergency visit includes a call-out fee to come out and diagnose, which differs from a standard daytime visit, and the repair is then quoted upfront. You’ll always know the full price before any work begins, so you can decide with complete information even in the middle of the night.
