It's 11 PM. You just discovered your water heater is leaking—or you went to shower and there's no hot water. Now what?

Water heater emergencies don't wait for business hours. Here's exactly what to do, when you need emergency service, and how Hot Water Heroes can help 24/7.

Step 1: Assess the Situation

Before calling anyone, take 2 minutes to understand what you're dealing with:

If Your Water Heater is Leaking:

Check where the leak is coming from:

Top of tank (inlet/outlet connections)
Side of tank (T&P relief valve)
Bottom of tank (drain valve or tank itself)
Under the tank (tank failure)

Minor leak from fittings? You may be able to wait until morning.

Active leak from tank bottom or significant water flow? This is a true emergency—the tank could release 40-75 gallons into your home.

If You Have No Hot Water:

Check these first:

Is the pilot light on? (gas units)
Has the breaker tripped? (electric units)
Is the thermostat set correctly?
Did someone accidentally close the gas valve?

If basics check out, you likely have a component failure requiring professional service.

Step 2: Turn Off the Water Supply

For any active leak, shut off the water to prevent flooding:

1. Locate the cold water inlet at the top of your water heater 2. Turn the valve clockwise to shut off water flow 3. If no valve exists, shut off your home's main water supply

No more water entering = no more water leaking.

Step 3: Turn Off the Heat Source

For gas water heaters:

Turn the gas control valve to "OFF" or "PILOT"
Do NOT attempt to relight until a professional inspects

For electric water heaters:

Turn off the circuit breaker for the water heater
Usually a dedicated 30-40 amp breaker

This prevents the unit from heating an empty tank (which causes permanent damage) and eliminates fire risk.

When You Need Emergency Service

True Emergencies (Call Now):

Active tank leak flooding your home
Gas smell near the water heater
Water heater making loud banging or pressure noises
Water temperature dangerously hot (scalding risk)
Electrical burning smell or sparking

Urgent but Not Emergency:

No hot water (uncomfortable but not dangerous)
Slow drip from fittings (annoying but contained)
Lukewarm water (inconvenient but manageable)

For urgent situations, you can wait a few hours or until morning if needed—but don't wait days.

What Emergency Service Costs

Emergency plumbing typically costs more than scheduled service. Here's what to expect:

Emergency service call (after hours): $100-200 Diagnostic + minor repair: $200-400 Emergency water heater replacement: $1,500-3,500

At Hot Water Heroes, we try to keep emergency pricing reasonable. We charge a modest after-hours fee but don't gouge you when you're in a tough spot.

Questions to ask any emergency plumber:

What's your service call fee?
Is the diagnostic included?
Do you have water heaters in stock for same-night replacement?
What's the total estimate before work begins?
