Each kitchen appliance leaks from predictable places and sends water in a predictable direction.
| Appliance | Where it usually leaks | Where the water goes |
|---|---|---|
| Refrigerator with ice maker or water dispenser | Thin supply line behind the fridge, the valve in the wall, or the drain pan | Under the fridge, into flooring and under nearby cabinets |
| Dishwasher | Supply line, drain hose, door gasket or a cracked tub | Under the dishwasher, into the subfloor and the cabinet next to it |
| Kitchen sink | Supply lines, faucet base, drain trap, garbage disposal | Inside the sink base, then under the floor and toe-kick |
| Water filter or reverse-osmosis system | Fittings and tubing under the sink | Inside the sink cabinet |
| Washing machine | See upstairs laundry leaks | Floor and the room below |
