## Description

Topvico Water Leak Sensor Detector Flood Alarm for Basement RV Moisture 120dB Work Alone Battery Operated 3 Packs

## Features

- Loud 120dB Alarm for Immediate Alerts -- The powerful 120dB alarm notifies you as soon as a leak is detected. The alarm continues until the water dries or the sensor is turned off, ensuring you don’t miss a potential flood, even from the basement. A cost-effective solution to prevent water damage in homes and businesses.
- High-Sensitivity 24K Plated Sensor -- Equipped with a premium 24K plated detection board for maximum sensitivity (if you no need high sensitivity, please try "B0BYHS79W5" with similar cost). Designed for repeated use - simply dry the sensor board after activation, and it’s ready to use again.
- Upgraded Easy Installation with Dual Mounting Options -- Features a double-sided adhesive sticker for effortless installation. One part secures the alarm unit, while the other attaches the water detection board. Choose from two mounting styles, as shown in the product images, to best fit your needs. Good for install in RV, fixed well with stickers, not move when driving.
- Comes with a 37.8-inch Cable -- easily extendable by the user up to over 150 feet using standard electrical wire (wire not included). Designed to detect water in hard-to-reach corners, it's perfect for monitoring rising water levels in sump pumps. Ideal for use in basements, near water heaters, underground spaces, washing machines, kitchens, RVs, and more -- a reliable solution for sump pump overflows and leak detection.
- Battery-Powered for Convenience -- Operates on a 9V battery (not included; good brand alkaline battery recommended). Provides up to 12 months of battery life under normal use. Low-quality batteries may last around 6 months, while frequent alarms or testing can shorten battery life.
