Water Heater Leak

Water Heater Leak Damage: what it covers

Quick answer

Water heater leak damage is water that escapes from a tank, a fitting or a pressure relief valve and spreads across the floor and into the surrounding materials. San Diego Water Damage Restoration sends a local crew to remove the water, dry the floor and wall behind the heater and check the cabinets and closets near it, across the City of San Diego ZIP areas.

Water Heater Leak Damage illustration for San Diego, CA

A water heater leak is usually found in the same place: on the floor by the tank, under the drain pan or in the closet that holds the heater. Most of the damage is not in the water on the floor, but in what is behind and under it. A tank that has leaked for a while can soak the wall, the subfloor and the cabinets around it, and the leak often stays hidden until the floor begins to move.

The first step is always the same: stop the supply to the heater and let the crew handle the water. A water heater is a tank of hot water connected to the supply and to the gas or electric controls, so the first call asks whether the heater is still connected, whether it is hot, and whether there is gas or power near the water. The answer changes what is safe to do before the crew arrives.

This page describes how the crew handles water from a water heater, what it dries and what it replaces, and what to ask a plumber about the heater itself once the water is out of the room.

Warning signs

Signs you need water heater leak damage

Turn off the gas and the power to the heater only if you can reach the controls safely. Do not stand in water while touching the heater or its electrical connections. Do not drain a hot tank yourself, since the water can scald. If you smell gas, leave the building and call the gas utility from outside. Keep children and pets away from the closet until the crew confirms it is safe.

A water heater drips into a closet with a wood floor

What homeowners notice
A homeowner notices a wet ring around the base of the water heater and a soft patch in the wood floor of the closet. The drain pan is full, and a faint musty smell is coming from the bottom of the door.
What we do
The crew asks the household to close the cold supply to the heater, confirms the gas or power is off at the heater's controls, and removes the standing water. The subfloor under the heater is read, and the wood floor is lifted in the closet where it cannot be dried in place. A plumber is called to replace the failed tank fitting.
What to expect
The closet floor is replaced after the subfloor reads dry, the plumber's invoice and the crew's scope are kept together, and the adjoining hallway is checked and cleared.

Options

Types and options for water heater leak damage

A small drip from the drain pan or a fitting

A small drip is often limited to the drain pan and the floor below it. The scope is usually small, and the crew can dry the floor in one visit. The fitting or the valve is then checked by a plumber, since a drip can come back as a larger leak.

A tank that has leaked under the base

A leak from the bottom of the tank can run under the heater and spread across the floor beneath it. The crew may need to lift the heater's base or the flooring to reach the wet material. The heater is not moved until a plumber has confirmed it is safe to do so.

A relief valve discharging into a closet

A relief valve that discharges water is a sign the tank is under pressure or temperature stress. The water can run along the discharge line and into the closet. The crew dries the closet and the wall, and the valve is tested by a plumber before the heater is returned to service.

Water that has run into the adjoining room

Water from a heater closet can run out under a door and into a hallway, a laundry area or a bedroom. The crew checks each room in the path, and it dries the subfloor and the baseboards that water reached before it stopped.

Should I turn off the heater or leave it on?

Turn off the heater's supply and its heat source if you can reach them safely, and leave the decision about a repair to a plumber. A heater left on with a leaking tank can keep producing heat and pressure, while a heater turned off with the supply closed can wait safely until the plumber arrives.

The gas or power control is on the heater itself, and the gas valve is labeled on most units. If you are unsure which control to turn off, do not guess. Call the line and describe the heater, and the crew will tell you what to do.

Do not drain the tank yourself. Draining hot water can scald, and it can add water to the floor. A plumber drains the tank as part of the repair.

Will the cabinets and the floor have to be replaced?

Not always. Cabinet bases and flooring that dry to standard can be kept, while those that swell, separate or stay wet usually must be replaced. The crew checks each piece with readings and tells you which are which.

Cabinet bottoms are often the first thing to fail, because they are made of particleboard that loses strength when wet. A cabinet that swells does not usually come back to its original shape, and the decision to replace it is made on the readings and the condition.

Flooring that lifts or cups may flatten again once it dries, or it may not. The crew explains which materials have a realistic chance of recovery and which do not, and that decision is written into the scope.

What should I ask the plumber about the heater?

Ask whether the tank is leaking, whether the relief valve is working and whether the heater should be repaired or replaced. Ask for the work in writing, and ask about the age of the unit and the warranty terms that apply to it.

A plumber can test the tank and the valve and tell you whether a repair is practical. A tank that has begun to leak from its body is usually replaced rather than repaired, and the plumber will say so.

Keep the plumber's invoice and the water removal scope together. Those documents show what was done and when, and they help the insurer and any later repair.

What moves the price of a water heater job?

The price depends on how much water reached the floor, how far it travelled, how much of the cabinetry and flooring must be removed, and how much drying the room needs. No figure is given on this site, and the price is explained and approved before work starts.

A heater in an open garage with a concrete floor is a different job from one in a closet with a finished floor and cabinets. The access and the materials count for more than the size of the water.

Ask for the scope before the drying starts and ask which items are being removed. A written scope lets you see the readings and the reasons for each removal.

How do I prevent a heater leak from becoming a larger one?

Check the drain pan and the area under the heater every few months, and keep the closet free of stored items that would hide a leak. Have a plumber inspect an older heater, and call the line at the first sign of water.

A drain pan works only if it drains to a safe place. Make sure the drain line is clear and that the pan is not holding water that has been there for a while.

Keep the area around the heater clear, so that a leak is seen quickly. Storing boxes against the tank is one of the most common ways a small drip stays hidden until the floor is damaged.

Our process

How our water heater leak damage visit works

  1. Shut the supply and the heat

    The technician asks you to close the cold-water supply valve to the heater and to turn off the gas or the power to the heater, if you can do so safely. The valve is usually above the tank, and the gas control is at the base. If you cannot reach the controls safely, say so, and the crew will guide you.

  2. Remove the standing water

    Once the heater is isolated, the crew removes the water from the floor and the drain pan. Water near the base of the heater is cleared first, then the water is pulled from the adjoining floor and the baseboards before drying begins.

  3. Check the materials behind the tank

    The wall behind the heater, the subfloor, the base of the cabinets and the adjoining closet are checked with a moisture meter. Water often runs behind the heater before it shows on the floor, so the readings are taken above the visible wet line as well.

  4. Dry the floor and the wall

    Air movers and dehumidifiers are set around the heater's closet and the adjoining room. Panels are opened where readings are high, and wet insulation or cabinet bases are removed where they cannot be dried in place.

  5. Refer the heater to a plumber

    The crew does not repair the heater. A tank that is leaking, or a relief valve that is discharging, needs a plumber to inspect and repair or replace it. The crew records the leak location and the photographs so the plumber can see the source quickly.

San Diego County

Why water heater leak damage is different in San Diego County and the towns around it

Water heater leaks are handled across all ten City of San Diego ZIP areas, and the crew works the same way in each. The closets and garages in each building are the places where the heater is found, and the crew checks the closet first.

Many of the water heaters the crew sees are in closets off a hallway or in a garage, where the floor drain and the back wall are close to the tank. The crew checks the wall and the floor behind the heater before it assumes the damage stops at the drain pan.

Heater calls are often routine, but they come at odd hours, when a tank finally lets go or a valve starts to discharge. The line is answered around the clock, and the crew is sent as soon as one is free.

FAQ

Water Heater Leak Damage FAQs

Can I stop the leak myself?

You can close the cold-water supply valve to the heater if you can reach it safely. Stopping a leak from the tank body or the fittings is a plumbing repair. Call a plumber for that, and call the line for the water removal and the drying.

Will the crew fix the water heater?

The crew does not repair the heater. It removes the water, dries the room and records the damage. A tank that is leaking or a valve that is discharging needs a plumber to inspect and repair or replace it, and the crew can name the trade needed.

Is a water heater leak covered by my insurance?

That depends on the cause and on your policy. Many policies treat sudden leaks and long-term seepage differently. Read your policy's water and maintenance terms, and ask your insurer about the heater specifically. This page does not promise any insurance outcome.

How quickly can the crew arrive?

Crews are dispatched as fast as one is available, around the clock. No arrival time is promised over the phone. While you wait, keep the supply closed and the area clear, and keep children and pets away from the water.

Does the floor have to come up?

Only where it cannot be dried. Sheet vinyl and tile can often be dried in place if the subfloor is dry. Wood and laminate that have lifted or cupped may have to come up. The crew checks each area and explains what it is recommending.

What happens if the heater leaks again after repair?

Call the line and the plumber together. A second leak can mean a fitting or a valve has failed, or that the repair did not address the cause. The crew can check the room again and record the readings for the plumber.
