6 reviews for Sonin Water Alarm with Flat Sensor 00701

  1. Paul C

    I work for a local municipal sewer department. Wish all houses had this. Would reduce the amount of basement damage due to blockages in the laterals.

  2. J Newton

    Works fine and the alarm is definitely LOUD

  3. Ray from PA

    I tested this before installing and it worked fine. I tested after about a year and is still working good.

  4. tmbink

    Wished I bought this 10 years ago.

  5. JR

    I had this alarm for over two years and pretty much forgot about it. At 3:30 this morning I was awoken by a beeping sound. My sump pump died and this gave me the warning I needed to swap it with a spare before flooding.

  6. Maggie

    Easy to install took only 5 min. Works great
