Water Overflow Sensor Attachment for Safety Technology Personal Alarms – Flood and Leak Detection, Connects to PAL-1 or PAL-1LIGHT, Suction Cup Mount, 27-Inch Sensor Cable, Basement and Appliance Use

The Damage Happens Before You Notice the Water

A water heater leak, a washing machine overflow, a slow basement flood — these aren’t dramatic events. They’re quiet ones. Water seeps, pools, and spreads while you’re asleep, at work, or in another part of the house. By the time you notice, the damage is done. Flooring ruined. Drywall soaked. Mold starting to form.

This sensor attachment turns your existing Safety Technology personal alarm into a water detection system. When the sensor contacts water, your alarm sounds — the same 130dB alarm that’s designed to get your attention in an emergency. It’s not a smart home system. It’s not Wi-Fi connected. It’s a sensor and an alarm. That’s all it needs to be.

Who This Sensor Attachment Is For

Homeowners who want early warning near water heaters, washing machines, and sump pumps. Renters who can’t install permanent leak detection systems but want some protection. Anyone with a basement that’s prone to moisture during heavy rain. People who’ve already dealt with water damage once and don’t want to deal with it again.

This is specifically designed as an add-on for the Safety Technology PAL-1 or PAL-1LIGHT alarm. If you don’t already own one of those units, you’ll need to purchase one separately for this attachment to function.

How It Works

The sensor attachment connects directly to a Safety Technology PAL-1 or PAL-1LIGHT personal alarm. The 27-inch sensor cable gives you flexibility to position the detection point exactly where water would appear first — on the floor beside a water heater, behind a washing machine, near a basement drain, or along the edge of a bathtub.

The included suction cup lets you mount the sensor on a smooth surface like a tiled wall, an appliance side panel, or a bathroom fixture. Position the sensor cable so its end rests at the lowest point where water would collect. When water touches the sensor, it completes a circuit that triggers the connected alarm. No delay, no notification chain — just an immediate, loud alert that water is somewhere it shouldn’t be.

It’s a low-tech approach, and that’s the advantage. There’s no Wi-Fi signal to drop, no app that needs updating, no battery in the sensor itself to die quietly. As long as the connected alarm is powered and working, the sensor is working.

Practical Details

Sensor cable length: 27.13 inches. Weight: 0.1 lbs. Color: Black. Includes suction cup for mounting. Requires a Safety Technology PAL-1 or PAL-1LIGHT alarm unit to function (sold separately). No batteries needed for the sensor itself — it draws from the connected alarm. No tools required for installation.

For about the cost of a cup of coffee, this attachment turns your personal alarm into a water leak detector. If you already own a compatible alarm, there’s very little reason not to have one of these near every water source in your home.
