How to choose
Match alarm volume to the distance
Alarm volume decides whether you hear the alert from another room. The Topvico and the TECKNET sound at 120dB, the Geevon and the GoveeLife sound at 100dB, and the Zircon sounds at 90dB. A louder alarm suits a detector placed in a basement or behind a closed door, while a lower volume suits a detector beside a bed. The GoveeLife volume adjusts, and the TECKNET volume reduces with a mute feature, so check how each alarm quiets after it sounds.
Check battery life and what is included
The GoveeLife gives a 5-year battery life, the TECKNET batteries run for more than 2 years, and the Topvico standby runs up to 2 years. The Geevon battery lasts about 12 months, and the Zircon needs a 9V battery that is not included. Check whether the battery comes in the box before buying, since the Topvico and Zircon batteries are not included.
Place detectors where water collects first
Place a detector where a leak shows up first: under sinks, beside water heaters, near washing machines and by sump pumps. The Topvico cable reaches hard-to-reach corners, the Geevon unit sits anywhere with its 3.15-inch diameter, and the GoveeLife mini size fits any place a leak may happen. The Zircon floats during flooding, and the TECKNET probes catch pipe drips from above and floor moisture from below. Cover each water source with its own detector.
