Water Heater and Appliance Leaks
Water heater, AC and appliance leaks in Mesa
Appliances that hold or move water fail quietly, often in a closet, garage or attic where nobody looks for days. Call to talk with an independent restoration contractor about drying out the damage.

What happens
The usual suspects
Tank water heaters can leak from the tank itself, the fittings on top or the relief valve line. A rusty base or a puddle that keeps coming back usually means the tank is near the end of its life. Shut off the water to it and, for gas units, set the control to off or pilot.
Air conditioners make water as they cool. That condensate runs through a drain line and sometimes a pan with a float switch; when the line clogs, the pan overflows, and an air handler in a closet or attic can soak the ceiling or floor around it. Rooftop evaporative coolers use a water supply line and pads, and a stuck float or a failed line can send water across the roof and into the house.
Washing machine hoses, dishwasher supply lines, refrigerator ice-maker lines and the supply hoses under sinks and toilets are other common sources. They are usually clean water at first, but water that sits for days can become harder to clean.
Right now
Quick checks
- Close the shut-off valve behind or under the appliance, or the main valve.
- Turn the appliance off at the breaker or unplug it, if you can reach it from a dry spot.
- Look at the floor and ceiling around the AC air handler for stains or soft drywall.
- Check the drain pan under the water heater or air handler for standing water.
- Photograph the appliance label and the leak point; insurers and installers ask for both.
- Keep the failed part if a plumber or appliance tech replaces it.
Local detail
Permits in Mesa
Water heater swaps
Mesa's residential FAQ says a like-for-like water heater of equal or lower rating needs no permit, while switching from a gas storage tank to a tankless unit does. Notify the gas utility before gas appliances go into service.
AC replacements
The same FAQ says a new air conditioner that uses the same or less electricity than the old one needs no permit; changing the electrical connections does.

Questions
Water Heater and Appliance Leaks: common questions
The water heater leaked into the garage. Is that serious?
A garage slab handles water better than a carpeted room, but water often runs under the wall into the house, into storage boxes or under cabinets. Check the drywall at the base of the shared wall and anything stored on the floor.
Why is my ceiling wet under the attic air handler?
A clogged condensate line or a failed drain pan is the usual cause. The AC technician clears the line; a restoration contractor checks the ceiling, insulation and walls for moisture.
Do I need a plumber or a restoration contractor?
Often both. The plumber or appliance technician fixes the source. The restoration contractor removes the water and dries what got wet.
