The SensXtend by LeakSmart extension kit with water sensor includes a SensXtend dock, rope sensor, extension cable and LeakSmart water sensor. When used with existing LeakSmart systems, the kit provides additional protection, customization and flexibility in detecting leaks in especially hard-to-reach areas of the home, such as under appliances. The SensXtend dock with Tri-Port design triples coverage by connecting up to three separate rope sensor lines that, when combined, provide up to 300 sq. ft. of additional leak protection. Rope sensors can be wiped dry and used again immediately for maximum protection and less downtime. LeakSmart.
