Water heater leak and flood cleanup in Casa Grande, AZ

What to do the moment it leaks

A water heater failure is one of the few water emergencies where your first few minutes really change the outcome. Work through these steps in order:

1. Shut off the water. There is a shutoff valve on the cold water line going into the top of the heater. Turn it clockwise to close it. If it is stuck or you cannot find it, shut off the water at the main instead.
2. Cut the power or gas. For an electric heater, switch off its breaker at the panel. For a gas heater, turn the gas control valve to the off position. This keeps the unit from running dry and heating an empty tank.
3. Stay out of the water if power is on. Do not wade into standing water near an electric heater until the breaker is off.
4. Move what you can. Pull boxes, belongings, and anything valuable up off the wet floor, especially in a garage where storage sits on the ground.
5. Call for extraction. The water is already spreading into the slab, the drywall, and the base of the walls. The sooner it comes out, the less you replace.

Why water heaters fail here

Casa Grande water is hard, and that is the main reason tanks fail early in this area:

• Sediment buildup. Minerals in hard water settle to the bottom of the tank and bake into a crust. That crust traps heat against the steel and makes the burner or element work harder, which wears the tank out faster.
• Corrosion from the inside. Hard water is rough on metal. The same water that causes slab leaks in copper lines corrodes the inside of a steel tank until it rusts thin and finally opens up.
• Age. Many tanks in Casa Grande give out around eight to twelve years, sooner than the same tank would last in a soft-water area. A unit past ten years old is living on borrowed time here.
• Where they sit. Heaters here are usually in the garage, a hall closet, or a utility closet. When one lets go in a closet or hallway, the water runs straight into finished living space instead of a floor drain.

Extraction and drying after a tank fails

Once the water is shut off, the crew gets the standing water out fast with truck-mounted and portable extractors. Then the real work is drying what soaked in. Water from a garage or closet wicks up into drywall and into the base of the walls, and it runs under baseboards and flooring into the next room. On the post-tension slabs common here, water spreads flat and wide under tile and laminate. The crew maps the moisture with meters, sets air movers and commercial dehumidifiers, and checks readings daily until the framing, subfloor, and drywall all read dry. Water from a clean tank is Category 1, low risk, but left sitting it degrades and grows mold within a day or two, so the drying does not wait.

Will insurance cover it?

A sudden tank rupture is usually covered under a standard Arizona homeowners policy, because it counts as sudden and accidental. The policy often will not pay for the failed water heater itself, but the water damage to your floors, walls, and belongings is generally covered. A slow leak you knew about and ignored is a different story and is often denied. The crews document the source, the category of water, and how far it spread, exactly the way an adjuster wants to see it, and can bill most carriers directly.

A water heater failure is one of the most common water losses in the area. For the full drying and restoration process, see our water damage restoration page, which also covers slab leaks and the other hard-water problems Casa Grande homes deal with.
