WATER PROTECTION · COMMERCIAL DRAFT
Water-leak protection for second homes: the launch shortlist
Compare systems for an unattended property by automatic action, outage behavior, freeze awareness and the need for a local responder.
The short answer
For a frequently unattended home, favor a layered design: automatic supply control where practical, targeted leak or freeze sensors, and a named local responder. An alert-only sensor is not a substitute for shutoff.
