A tray contains some of the water; a detector recognizes water at its point of contact; an external valve can shut off the supply. None of these elements repairs a leak or necessarily covers all of its paths.
What each measure can do
| Measure | Scope | Main limitation |
|---|---|---|
| Tray without drain | Retains a limited volume | Can overflow if the leak continues |
| Tray with drain | Directs collected water to a designated outlet | Depends on installation and drainage capacity |
| Point detector | Alerts when water reaches its sensor | Does not detect water that follows another path |
| External automatic shutoff | Stops a supply point when activated | Leaves out leaks upstream of the shutoff or water already present |
Physical compatibility and access
The tray must accommodate the appliance dimensions, feet, and operation without affecting the support. Its edge must not block filter opening or removal for service. The detector is placed where it can receive water from the area to be protected, in accordance with its procedure.
A tray outlet requires proper drainage; it should not be connected by guesswork to any pipe, and drains should not be blocked to prevent odors.
Integrated protection and environmental protection
The machine's leak protection systems operate within its architecture. External measures protect aspects of the site. If a protection device alerts repeatedly, find the leak rather than adding more containers to keep washing.
Choose each measure based on the water path it can actually detect or contain.
