Water Heater Leaks in Morrisville: Garage, Closet and Attic Tanks

Where the tank sits changes the damage

Local homes place water heaters in garages, closets and some attics. Single-family homes sit on vented crawl spaces or slabs, and townhome rows mostly sit on slabs, so water finds a different route in each house.

Garage tanks

Water spreads across the slab, toward the door and under stored boxes. Concrete takes in little water, so the main risks are drywall at the base of the walls, cardboard storage and anything plugged in near the floor.

Closet tanks

A closet tank sends water into the wall framing, under the flooring of the hall and into neighboring rooms. Vinyl, laminate or wood floor beside the closet can end up wet before the leak is noticed.

Attic tanks

Water runs through insulation and the attic floor, then stains and softens the ceiling drywall below. By the time the stain appears, the ceiling cavity is usually soaked.

Early signs a tank is on its way out

Tanks wear out from the inside, and small clues show up before a full failure. Tanks in garages and closets get a glance only rarely, so a quick look every few months is worth it.

• Rust stains or flaking at the base of the tank.
• Damp insulation or a wet spot on the floor near the tank.
• Water dripping from the relief valve discharge pipe.
• Rumbling or popping while the tank heats.
• Rusty hot water from the taps.

First steps when a tank leaks

Stopping the water, then the power or fuel, keeps the situation from getting worse. The order below works for most tank heaters.

Water

The cold water supply valve sits on the pipe above the tank. Closing it stops new water from entering, though the tank may keep leaking what it already holds.

That hot water can scald, so draining the tank by hand should wait until it has cooled.

• Close the cold water supply valve on top of the tank.
• Keep clear of any hot water coming from the relief valve pipe.

Power or gas

An electric heater should be switched off at its breaker. A gas unit has a control knob that can be set to off.

If there is a smell of gas, everyone leaves the house and the gas utility is called from outside.

• Switch off the breaker for an electric heater.
• Set the gas control to off for a gas unit, and leave the house if gas can be smelled.
• Stay away from standing water near outlets and cords.

Photos and belongings

Pictures of the tank, the leak and the wet area help the plumber and the insurer. Boxes, tools and furniture near the tank are lifted out of the water as soon as it is safe.

• Photograph the tank label, the leak and every wet surface.
• Move stored items and furniture out of the path of the water.

What the extraction and drying crew does

Water heater leak cleanup begins with removing standing water, then finding where it traveled. Moisture meters and thermal cameras show wet framing behind finished surfaces.

Water extraction uses pumps and wet vacuums, and then dehumidifiers and air movers take over the drying.

On a slab, the crew checks where water traveled beneath the flooring, since vinyl and laminate planks can trap water that never shows on the surface.

• Standing water is extracted from floors and low spots.
• Wet baseboards and low drywall are removed where readings call for it.
• Flooring is lifted if water sits under it.
• Wall and ceiling cavities are opened to dry.
• Readings are repeated until the materials read dry.

How floors and walls react to a tank leak

Materials near the tank take the first hit, and each one reacts differently. The cleanup plan depends on what is under and around the heater.

Townhome rows add a wrinkle. A closet tank can send water across a shared wall, so telling the neighbor and the association early keeps the loss from growing.

• Tile and sealed concrete tolerate water and are cleaned and dried.
• Vinyl and laminate can trap water underneath and are often lifted.
• Hardwood can cup or buckle and needs moisture readings before any decision.
• Carpet and pad hold water and are usually removed.
• Drywall draws water upward from the floor and is cut out where readings run high.

Attic tanks and the ceiling below

An attic leak is the one most likely to go unseen. The water soaks insulation, saturates the attic floor and only then shows as a stain on the ceiling.

Ceiling leak water damage work removes wet insulation, cuts out sagging drywall and dries the joist bay. Light fixtures under the stain should stay off until they have been checked.

Replacing the tank and preventing a repeat

A leaking tank is replaced rather than patched, and a plumber handles the swap. A drain pan with a drain pipe under the tank, plus a working relief valve, helps catch smaller leaks.

The drying time estimator gives a rough idea of how long drying may take for a given room size.

• Ask the plumber about a drain pan with a drain pipe.
• Flush sediment from the tank as part of routine care.
• Replace an older tank before it fails, not after.
• Keep stored items off the floor near the tank.
