Our Review
The cheapest insurance an under-sink system can have, the Watts FloodSafe connector senses the sudden surge of a burst line and shuts the water off automatically — the difference between a minor fix and a ruined kitchen floor.
It installs inline on the supply with standard connections and resets by hand once you've addressed the cause. For the price of lunch, it's the kind of small upgrade every RO or filter owner should add.
Pros
- Stops a burst supply line from flooding the cabinet
- Dirt-cheap peace of mind
- Standard connector sizes
Cons
- Protects against burst lines, not slow drips
- Must be sized to your supply connection
The HU Recommendation
Add one to every under-sink connection on your filter or RO system. It won't catch a slow drip, so still check fittings periodically — but it stops the catastrophic failures.
