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.

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.

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.
