The Water Overflow Sensor Attachment connects to the PAL-1 or PAL-1LIGHT personal alarm and turns it into a water detection device. When the sensor contacts water — from an overflowing washing machine, rising basement water, or an unattended bathtub — it triggers the connected alarm immediately. Comes with a suction cup for fixed mounting near the water source. No separate alarm unit required — uses the one you already have.

  • Connects directly to the PAL-1 or PAL-1LIGHT personal alarm (alarm sold separately)
  • Sensor detects water contact and triggers the connected alarm instantly
  • 27″ sensor wire gives placement flexibility near water sources
  • Suction cup mount included for fixed positioning on walls, floors, or appliances
  • Useful near washing machines, water heaters, bathtubs, and in basements

Turn Your Existing Alarm Into a Flood Sensor

If you already own a PAL-1 or PAL-1LIGHT, this attachment adds water detection without buying a separate device. The sensor sits at floor level near a potential water source. When water reaches the sensor — whether from a slow leak, an overflowing appliance, or rising groundwater — it completes a circuit that triggers the alarm immediately. The suction cup keeps the sensor in a fixed position so it stays where water would accumulate first.

Who This Water Sensor Attachment Is For

Homeowners with appliances that have a history of leaking or overflowing — washing machines, water heaters, refrigerators with ice makers, or dishwashers. A slow leak behind a washing machine can cause significant water damage before it’s visible. This sensor catches it early.

People with finished basements or below-grade living spaces where any water intrusion causes immediate damage to flooring, walls, or stored items. The sensor sits at floor level and triggers before water spreads across the room.

Renters and homeowners who leave appliances running while away from home — at work, running errands, or overnight. The alarm triggers at the source so you know about a problem while you can still limit the damage rather than discovering it hours later.

Is This the Right Choice for You?

Choose the Water Overflow Sensor if you want:

  • A low-cost way to add flood detection using a PAL-1 or PAL-1LIGHT you already own
  • Immediate audible alert when water reaches the sensor — no app or Wi-Fi required
  • Flexible sensor placement with a 27″ wire and suction cup mount
  • A simple, passive solution that requires no configuration or subscription

Consider something else if you need:

  • A standalone water alarm that doesn’t require a PAL-1 or PAL-1LIGHT unit — this is an attachment only
  • Smart home integration, remote alerts, or phone notifications when you’re away from the building

How the Sensor Works and Where to Place It

The attachment plugs into the PAL-1 or PAL-1LIGHT and uses a conductive sensor at the end of a 27″ wire. Water conducts electricity — when water contacts the sensor probes, it completes the circuit and sends a signal to the connected alarm, which activates immediately at full volume. There’s no threshold to configure and no delay built in. Contact triggers the alarm.

The 27″ wire gives you enough reach to position the sensor at the lowest point near a potential leak while keeping the alarm unit mounted higher — on a wall, shelf, or appliance surface — where it stays dry and audible. The included suction cup holds the sensor against a flat surface like a tile floor, bathtub surround, or the side of a washing machine pedestal.

For washing machine use, place the sensor on the floor directly below the drain hose connection — the most common failure point. For water heaters, position it at the base of the unit where the first signs of tank failure appear as a slow seep. In basements, place it at the lowest point of the floor where water would accumulate first during heavy rain or sump pump failure.

Practical Details

Sensor wire length: 27.13″. Sensor probe diameter: 0.13″. Weight: 0.1 lbs. Includes suction cup for mounting. Requires a PAL-1 or PAL-1LIGHT alarm unit, sold separately. No batteries or additional hardware needed beyond the connected alarm. Manufactured by Safety Technology.

If you own a PAL-1 or PAL-1LIGHT and want early warning before water damage becomes a repair bill, this attachment adds that capability for a few dollars and takes about two minutes to set up.

Frequently Asked Questions

Will this work with any personal alarm, or only the PAL-1 and PAL-1LIGHT?

This attachment is specifically designed to connect with the PAL-1 and PAL-1LIGHT personal alarm units from Safety Technology. The connector is proprietary to those models. It won’t plug into other alarm brands or unrelated devices. If you don’t already own a PAL-1 or PAL-1LIGHT, you’ll need to purchase one of those units alongside this attachment for the system to work.

How much water needs to contact the sensor before the alarm triggers?

The sensor responds to a thin film of water across both probes — it doesn’t require standing water or a specific depth. A slow seep from a leaking appliance or the first signs of water rising from a drain backup are generally enough to activate the alarm. This makes it useful for catching problems early rather than after significant accumulation. The exact trigger threshold can vary slightly by water mineral content, but the sensor is calibrated to respond to ordinary tap water and groundwater reliably.

Can I leave the sensor permanently installed near an appliance?

Yes. The suction cup mount is designed for fixed positioning. You can leave it in place near a washing machine or water heater indefinitely. The sensor itself has no moving parts and no components that degrade from normal ambient humidity — only water contact triggers the alarm. For outdoor or fully exposed locations, a weatherproof standalone sensor would be more appropriate, but in typical indoor appliance and basement applications, permanent installation is practical.

Does the sensor attachment drain the PAL-1 battery faster when connected?

The sensor draws minimal current during standby — it’s essentially a passive conductor waiting for water to complete the circuit. Battery consumption from the sensor attachment alone is negligible and won’t meaningfully reduce the runtime of the connected PAL-1 or PAL-1LIGHT. Battery use increases only when the alarm is actively sounding, which is the same as normal alarm operation.
