What to do the moment you find a water heater leak
- Shut the cold supply valve
Close the valve on the cold line above the tank, or the main if you cannot reach it.
- Turn off power or gas
Switch off the breaker for an electric heater, or turn a gas heater's control to off or pilot.
- Move stored items
Lift boxes and belongings off the wet garage or closet floor.
- Photograph the tank and floor
Take photos of the tank, the label and the water before anything is moved.
Most Hayward homes keep the water heater in the garage, a hall closet or a utility room. Tank heaters usually last around 8 to 12 years, and many in the city's postwar housing stock are on their second or third replacement. When the tank fails, it either weeps from the bottom for weeks or splits and releases 40 to 50 gallons at once, with the supply still refilling it.

How a water heater leak is handled in Hayward
IICRC S500 is the industry drying standard. It sets the order of the work, and the equipment stays until the readings say dry, not until the room looks dry.
- 01
Map the moisture first
The tech who does the walkthrough traces the source, then maps wet materials with thermal imaging and pinless meters before any equipment goes down.
- 02
Extract the standing water
The extraction crew pulls water with truck-mounted extraction, so it leaves the building instead of wicking into the next room.
- 03
Set the drying to the room
The drying team places air movers to each room's evaporation load and runs LGR dehumidifiers, with desiccants for Class 4 materials.
- 04
Verify dry, then document
Most crews log readings daily and pull equipment once wet materials sit within 2 to 4 points of a dry reference material.
Signs a water heater is failing
- Water or rust stains around the base of the tank
- A dripping pressure relief valve or discharge pipe
- Rust-colored hot water or popping sounds from sediment
- Damp drywall or baseboard on the wall behind a closet heater
What the water reaches
In a garage, water spreads across the slab and under stored boxes, and it wicks into the drywall and the bottom plate of the shared wall with the house. In a hall closet or utility room, it runs under flooring into bedrooms and hallways. The tech who does the walkthrough maps moisture past the visible puddle, because the damage almost always reaches further than it looks.
The extraction crew pulls standing water, then the drying team lifts wet carpet pad or laminate, removes baseboard and cuts drywall where readings show wicking. Air movers and LGR dehumidifiers run until the framing and slab meet the drying goal.
Trade fact: a slow leak that ran for weeks is often treated differently from a sudden rupture, both in the drying plan and on an insurance claim. The moisture map shows how far the water went and how long it has been there.
After the dry-out
A plumber replaces the tank. Many homeowners add a drain pan, a leak sensor or an automatic shutoff valve at the same time, especially for a heater inside the living space.

How do I know if the tank or a fitting is leaking?
Water at a fitting or valve on top is often a connection. Water from the bottom of the tank usually means the tank itself has failed.
Can I keep using hot water?
Not from a failed tank. Shut the supply and the power or gas until a plumber replaces it.
Does the garage drywall need to come out?
Only where readings show it wicked water. A flood cut above the baseboard is common on the wall shared with the house.
How long does drying take?
Usually two to four days for a garage slab and wall base, longer if the water ran under flooring inside the house.
Should I add a drain pan?
A drain pan, leak sensor or automatic shutoff is a common upgrade, especially for heaters in closets or upstairs.
Is water heater damage covered?
A sudden rupture is often reviewed differently from a slow leak. Coverage depends on your policy, so it is worth checking with your own insurer.
