Phcc Pro PWA2 Water Alarm

The Phcc Pro Series PWA2 is a battery-powered water detector and alarm designed to alert you to leaks or rising water. It operates on a 9V DC supply and produces a 110 dB audio signal. The unit features an ABS housing and can be placed on the floor or mounted for installation. A sensor wire is included to detect moisture in the target area.

Ideal for Leak Detection Only

This device suits homeowners or technicians needing an audible warning for water presence in basements, near sump pits, or around appliances. It is not suited for applications requiring automatic pump activation, wireless notifications, or integration with building management systems. Buyers needing a shut-off valve or smart-home connectivity should look at other solutions.

110 dB Alarm Sound Level

The decisive specification is the 110 dB alarm sound level, which determines how far the warning can be heard through walls or floors. If the installation area is noisy or distant from occupied spaces, this output may be insufficient. Verify that the sound level meets the audibility requirements for your specific location before purchase.

Questions about this item

Should I choose the 9 V DC model or a different voltage version?

The unit is offered only in a 9 V DC version, so no alternative voltage option exists.

How loud will the 110 dB alarm actually sound in a basement?

At 110 dB the tone is comparable to a chainsaw at close range and will be clearly heard through a closed basement door.

What connection standard does the sensor wire use and what length limit does it impose?

The sensor wire connects via simple exposed leads; no formal interface standard is defined, so the practical limit is the wire length supplied in the box.
