Guards+ RO System Leak Stop

Description

The Guards+ RO System Leak Stop is a compact safety device designed to automatically shut off water to your reverse osmosis system when a leak is detected. Installed directly on the feed water line, it provides instant protection against water damage—especially in under-sink installations where leaks can go unnoticed.

• Automatic Leak Detection: Shuts off water supply when moisture is detected
• Water-Activated Shut-Off: Internal absorbent pad expands to trigger valve closure
• Prevents Water Damage: Stops leaks before they cause costly cabinet or floor damage
• Simple & Reliable Design: No power or electronics required
• Compact & Discreet: Fits easily under sinks or near RO systems
• Easy Installation: Installs inline on 1/4″ RO tubing
• Resettable System: Replace tablet and reset after activation

Compatibility

The Guards+ Leak Stop is compatible with:

• Reverse osmosis drinking water systems
• Under-sink filtration systems
• Ice maker and fridge water lines (1/4″ tubing)

📌 Designed for low-flow residential systems using standard 1/4″ OD tubing.

Specifications

• Product Type: Mechanical leak detection shut-off valve
• Connection Size: 1/4″ push-fit (inline)
• Activation Method: Water-activated absorbent pad
• Material: High-strength plastic body
• Power Requirement: None (fully mechanical)
• Reset Method: Replace internal tablet and reset plunger

Applications

The Guards+ RO Leak Stop is ideal for:

• Under-sink reverse osmosis systems
• Cabinets and finished areas where leaks could cause damage
• Rental properties or unattended installations
• Preventative protection for homeowners

💡 RO systems have multiple fittings and connections, so adding a leak stop provides an extra layer of protection against unnoticed leaks

How It Works

1. Installed inline on the RO feed water line
2. Sits on the cabinet floor beneath the system
3. If a leak occurs, water contacts the internal tablet
4. Tablet expands and triggers the shut-off valve
5. Water flow to the RO system stops immediately

Maintenance

• Keep the unit in a dry location (avoid splashing)
• Replace the absorbent tablet after activation
• Periodically inspect for dust or debris
• Test occasionally to ensure proper operation

⚠️ Pro Tip (Real-World Insight)

While these devices are very effective, they can occasionally trigger from minor moisture (false trips) if placed in a damp area. Proper placement—away from normal splashes—is key to reliable performance.
