Why does a heater leak go unnoticed for so long?
Because the water runs into the space under the tank or behind it, and the pan or floor takes it up first. A slow leak can soak the floor for weeks before a stain or soft spot appears.
Heaters sit in utility rooms and closets that are seldom looked at. A tank that drips only when it heats can keep the same schedule for a while before anyone notices.
A check of the base, the connections and the drain pan at the start of each season is the simplest protection. A dry pan and a clean floor are the sign of a sound unit.
What should I do when a heater is leaking?
Turn off the power or gas at the heater, close the cold supply and call. Do not touch the relief valve, and do not drain a hot tank yourself unless a plumber has said how.
A tank under pressure can release a large volume quickly, so close the supply and keep children and pets clear while the tank cools.
If the water is near an outlet or the panel, leave the area and call from outside.
Do washers and dishwashers need replacing after a leak?
Not always. Hoses, drain connections and pumps are usually replaceable, and the appliance itself can often be repaired. The decision depends on the age of the unit and where the leak came from.
A technician can tell whether the leak is from a failed hose, a cracked tub or a failed seal. The crew does not decide the repair, but it records the source.
Keep the appliance out of use until it has been checked, and do not plug it in while the floor under it is wet.
Will the insurer pay for an appliance leak?
Many standard policies cover sudden water damage from an appliance, but they often exclude the appliance itself, and wear or gradual leaks may not be covered.
The record should include the appliance, the photographs of the source and the water path, and the drying log. A failed part kept for the insurer can be as useful as any photograph.
Ohio's Department of Insurance takes complaints about claim handling, after the insurer has been asked in writing to explain its position.
Isolating the tank and the pan
The tank is isolated from power and water before anything else is done.
A water heater that leaks needs to be isolated first. The crew confirms the power or gas is off, closes the supply and drains the tank as far as it can be drained safely. A heater that is still hot or pressurised is left to a plumber.
The pan under the tank is checked for its drain line. A pan that overflowed because the drain line was blocked is a different problem from a tank that failed, and the scope records which one was found.
- Confirm the power or gas is off
- Close the water supply to the tank
- Drain the tank as far as is safe
- Check the pan and its drain line
- Record which failure was found
Removing the base and drying the subfloor
The cabinet base and the floor under it are removed and dried to readings.
Water from a heater often runs under nearby cabinets and into the floor beside the closet. The crew removes the wet cabinet base where it is swollen, extracts the water under it and reads the subfloor at the joist ends.
The new cabinet and the new heater are trade jobs. The crew records the area removed and the readiness of the floor.
- Remove the swollen cabinet base
- Extract water under the cabinet
- Read the subfloor at the joist ends
- Hand the cabinet and the heater to trades
- Confirm the floor is ready in writing
