Reliance Detection Technologies (RDT) provides comprehensive, commercial-grade solutions for indoor plumbing leak detection and water damage mitigation. Our reliable, easily deployed water sensor, alarm, notification, and automatic water shut-off technology protects commercial and residential properties against damage from undetected leaks. We have nearly a decade of experience helping specifiers protect commercial properties, healthcare and assisted living facilities, multi-unit residential properties, homes and more from plumbing leaks.

RDT’s FloodMaster® line is made in the USA and has long been one of the most trusted names in affordable, dependable leak alarm and automatic shut-off systems. Appliance kits sound an alarm and automatically shut off the water supply to a water heater/tank, washing machine, dishwasher, beverage dispenser or other hose-fed appliance when a leak is detected. Wide-area systems for spaces like kitchens, bathrooms, breakrooms and mechanical rooms provide leak detection with water main control. Simple water leak alarms are also available to monitor plumbing fixtures, HVAC condensate pans and more.

Most FloodMaster systems feature dry contacts to interface with a building automation system, security panel or appropriate relay. Plenum-rated leak detection kits are available with plenum-rated wiring and step-down transformer (120, 208, 240 VAC to 24 VAC) in lieu of standard wall wart. A variety of accessories make it easy to design customized systems to meet any application requirement.

Wireless systems with smartphone app-based leak notifications and system management are also available to cover large areas.

All products are backed by a 3-year warranty. RDT offers a variety of resources to help specifiers choose the best solution for their projects. Visit or call 888-771-4929 for assistance.
