Is a Water Heater Leak an Emergency? When to Call Immediately

Technician repairing a corroded leaking water heater
Lowcountry humidity accelerates water heater corrosion — early detection saves tanks.

It is 11 p.m., you found water by the heater, and you are wondering whether this can wait until morning. Fair question — emergency rates are real money. Here is how to triage it yourself: five red flags that mean call now, and the situations that can safely wait for a morning appointment.

Red flag 1: active, spreading water

Water visibly advancing across the floor — not a damp spot, an advancing front. Shut the supply valve, cut power/gas, and call. Every hour of spread in our humidity is an hour of soaking into materials that will not dry on their own.

Red flag 2: any gas smell

Leave the house and call your gas utility or 911 from outside. This outranks every other consideration on this page. Once cleared, call us for the repair.

Red flag 3: the tank shell is leaking

Water weeping from a seam or the jacket base — not a fitting, the tank itself. Shell failures can widen without warning and release the full tank. Shut it down and call.

Red flag 4: scalding water plus T&P discharge

Overheating with the relief valve open means the safety systems are actively working. Do not 'wait and see' on an overheating tank — call.

Red flag 5: water near electrical components

Water in or around the heater's electrical compartment, or a tripping breaker paired with moisture. Cut the breaker and call — water and electricity do not negotiate.

What can wait until morning

A slow, steady drip from a visible valve or fitting with the supply shut off and a bucket catching it; a damp pan with no active flow; condensation you have confirmed with the persistence test. Shut things down, contain it, and call (833) 713-2101 first thing — mention it is non-urgent and we will schedule accordingly.

What info should I have ready when I call?

Whether water is actively spreading, gas or electric, what you have shut off, and the heater's age if you know it. Photos help if you can take them safely.

Can you really come at 2 a.m.?

Our emergency line is answered around the clock and we dispatch for true emergencies overnight. Call (833) 713-2101 — if it can wait, we will tell you so.
