Emergency water heater repair starts with two moves you can make yourself. If a water heater is flooding a closet, dripping through a ceiling or blowing off steam right now, stop the water and the fuel first, then call or text (830) 243-5644. Someone answers every hour of every day, and you'll get a call right back. That holds from the older homes near Landa Park to acreage out FM 306.

Leaking right now? Three things before anything else

1. Shut off the water. Turn the cold-water supply valve on the pipe at the top of the heater clockwise until it stops.
2. Cut the power. Electric unit: switch off its breaker at the panel. Gas unit: turn the gas control knob on the front of the heater to OFF.
3. Then call or text (830) 243-5644. Answered 24/7, and you'll get a call right back.

Smell gas? Leave the house, don't flip any switches, and call 911 and then CenterPoint Energy's leak line at 888-876-5786 from outside.

How do you shut off a water heater in an emergency?

The three steps above are the short version. Here is the detail for valves that stick, lever handles, and gas lines.

1. Stop the water. Turn the cold-water valve on top of the heater clockwise until it stops, or a quarter turn on a lever-style valve. If it's seized, shut the main at the meter box near the street.
2. Cut the fuel. Gas: turn the control dial to OFF, then close the supply valve so its handle sits across the pipe. Electric: switch off the double breaker for the water heater, because a draining tank must never stay powered.
3. Open a hot tap. It relieves the pressure still inside the tank.
4. Call or text. Say "active leak" first, then where the heater sits and whether it runs on gas or electric.

Emergency or can it wait until morning?

Some problems can't wait an hour; others can wait for daylight and cost less. Here's how to tell the difference.

• Water from under the jacket or a split fitting: emergency. The cold inlet keeps refilling the tank as it drains.
• A stain, a sag or a drip through a ceiling: emergency. An attic water heater is already failing.
• A gas smell: leave first, touch no switches, and call 911 and CenterPoint's leak line (opens in a new tab) from outside.
• The relief valve discharging, or scalding water at the taps: urgent. Water at 140°F scalds in about 5 seconds (opens in a new tab), so cut the fuel and call.
• No hot water with a baby, an elderly or an unwell person at home: urgent; say so on the call.
• A lukewarm shower or a pilot that went out once: a daytime repair call.

A tankless water heater holds far less water, but a leak still calls for the same first moves: close its isolation valve and cut the fuel.

Not sure whether a slow drip counts? The leaking water heater guide walks through where leaks start, from the drain valve to the tank body, and what each source means.

What happens when you call at night?

Give your name, number, ZIP and what's happening, and you'll get a call right back. That call settles whether it needs a visit tonight or first thing in the morning, once the water is off.

You'll get a price before any work starts, even in the middle of the night. After-hours visits usually cost more, so ask about it on the call rather than finding out later.

Three details speed things up:

• Is water still running? Say whether the shutoff worked.
• Where does the heater sit? Garage, closet or attic.
• Which fuel? Gas, electric or propane, and roughly how old the tank is.

What does an emergency repair visit cover?

The first goal is a safe, dry house; the fix may come next. A sound emergency visit usually looks like this:

• Make it safe: water isolated, gas or power off, and the relief valve checked.
• Find the source: a fitting, the drain valve or the relief line can often be repaired on the spot.
• Call it honestly: a tank leaking from the shell can't be repaired, and a replacement follows with the permit filed.
• Price first: any repair or replacement is priced before the work begins.

How much does emergency water heater repair cost?

A typical repair visit runs $200–$850 before any after-hours charge. A failed tank is a different number: a standard tank replacement runs about $1,000–$3,400 installed.

An after-hours charge is common in the trade, and its size varies. Ask for it before you agree to a visit.

Both figures are typical ranges compiled from national cost guides and rounded; how the ranges are built.

Limiting the damage in a New Braunfels home

Water finds the lowest point. From a garage water heater it runs down the driveway; from a closet it soaks the flooring and both walls; from an attic it comes through the ceiling. In Texas generally, attics were a popular spot for water heaters over the last 50 years, so check above you if you have a stain.

Move rugs, boxes and anything electrical out of the water's path. If a wall with outlets is getting wet, switch that circuit off at the breaker.

For next time, three things help:

• A drain pan with a drain line: required by 2021 International Plumbing Code section 504.7 (opens in a new tab) wherever a leak would damage the home.
• A leak sensor with automatic shutoff: worth it on any attic or closet unit.
• A planned swap: a tank past 12 years in water this hard is better replaced on your schedule than after a flood.

The City requires a permit (opens in a new tab) to replace a water heater, so an emergency replacement still gets one. The fee isn't published; it belongs on the estimate.
