The Cheapest Water Damage Insurance You’ll Ever Buy
A washing machine hose doesn’t announce when it’s about to fail. Neither does a water heater. By the time you notice the puddle spreading across the floor, the damage is already done — and water damage repair is rarely cheap. This overflow sensor attachment gives your PAL-1 or PAL-1LIGHT alarm a second job: watching for water so you don’t have to. The moment the sensor tip makes contact with moisture, it triggers the alarm. That’s the whole mechanism. Simple, reliable, and it costs less than an hour of a plumber’s time.
Who This Sensor Attachment Is For
Homeowners with older appliances will find this particularly useful. Washing machine hoses have a finite lifespan, and water heaters don’t always give warning before they fail. Placing this sensor near the base of either appliance gives you an early alert before water spreads to flooring, drywall, or subfloor.
Renters are another good fit. You may not own your appliances, but you’re still responsible for what happens in your unit — and a leak from an aging washing machine can become your problem fast. This sensor gives you a heads-up before it becomes a landlord conversation.
Anyone with a basement, sump pump, or low-lying utility room has reason to keep one of these near the floor. Flooding often starts slowly. An early alert means the difference between mopping up and calling a restoration company.
Is This the Right Choice for You?
Choose this sensor attachment if you want:
- An affordable water detection add-on for your existing PAL-1 or PAL-1LIGHT alarm
- Early warning near washing machines, water heaters, or basement drains
- Tool-free installation with the included suction cup mount
- A simple mechanical sensor with no Wi-Fi or app required
Consider something else if you need:
- A standalone water alarm that doesn’t require the PAL-1 or PAL-1LIGHT base unit
- Remote smartphone notifications when water is detected
How It Actually Works
The sensor attachment connects directly to the PAL-1 or PAL-1LIGHT personal alarm through its accessory port. The sensor lead — just over 27 inches long — gives you enough reach to position the detection tip at floor level while the alarm unit sits higher on a shelf or wall mount. When water contacts the sensor tip, the circuit completes and the alarm fires. There’s no delay, no calibration, and no programming involved.
The included suction cup makes mounting straightforward. Press it to the side of a washing machine, the base of a water heater, or the wall of a utility room, and position the sensor tip at the level where you want detection to begin. Most people aim for just above floor level — enough to catch a small leak before it spreads, but high enough to avoid false triggers from normal condensation or mopping.
Because the sensor relies on the PAL-1 or PAL-1LIGHT for its alarm output, the volume and features of whichever base unit you’re using apply here. The PAL-1LIGHT, for example, adds a strobe function to the alert.

Practical Details
The sensor lead measures 27.13″ in length and the unit weighs 0.1 lbs. Compatible with the PAL-1 and PAL-1LIGHT personal alarms. Includes a suction cup for mounting. Color is black. Manufactured by Safety Technology. This attachment does not function without a compatible PAL base unit.
If you already own a PAL-1 or PAL-1LIGHT, this attachment turns it into a water leak detector for a fraction of what water damage actually costs. Pick one up while you’re here.
Frequently Asked Questions
Does this work with any personal alarm, or only the PAL-1 and PAL-1LIGHT?
This sensor attachment is designed specifically for the PAL-1 and PAL-1LIGHT personal alarms from Safety Technology. It connects through the accessory port on those units. It is not compatible with other brands or models of personal alarms. If you don’t already own a PAL-1 or PAL-1LIGHT, you’ll need to add one to your order.
Where exactly should I position the sensor tip?
Position the tip just above floor level — typically about a quarter inch off the ground. This catches water early without triggering false alarms from normal floor moisture or cleaning. Near a washing machine, place it at the back corner closest to the drain hose. For water heaters, position it at the base where a slow leak would pool first.
Will condensation or humidity trigger false alarms?
The sensor is designed to detect standing water contact, not ambient humidity. Normal condensation on a cold pipe or typical basement humidity should not trigger it. However, if moisture is pooling on the surface where the sensor tip rests — such as heavy condensation dripping onto the floor — it could activate. Positioning the tip slightly above floor level helps minimize this.
