The AquaFX Leak-Stop Valve Water Detector is an essential safety device for saltwater aquariums, specifically designed to prevent water damage from leaks. It automatically shuts off water flow in seconds upon detecting moisture, utilizing a simple mechanical design to provide reliable flood protection for RO/DI systems and other critical water lines. This proactive measure safeguards your home and aquarium equipment from potential costly mishaps.

This leak detector features quick-connect push fittings, available in a 3/8" size, allowing for easy installation in just seconds without the need for power or batteries. Its simple, reliable mechanical design operates by expanding a super-absorbent pad upon water detection, which then pushes a valve to halt water flow. The unit is reusable, requiring only the replacement of the included absorbent pads, and comes with three pads, two retainer clips, double-sided tape, and screws for comprehensive setup.

Ideal for any reef aquarist seeking peace of mind, the AquaFX Leak-Stop Valve is perfect for placement around sumps, near the aquarium itself, or at water stations, especially those utilizing RO/DI systems. Its non-powered, mechanical operation ensures continuous protection even during power outages, making it an indispensable tool for preventing floods and mitigating the significant risks associated with saltwater leaks in sensitive home environments.
