Drain Alert® — Condensate Safety Switches, Pan Sensors & Leak Alarms

Drain Alert specializes in condensate overflow protection that helps contractors prevent water damage, emergency call-outs, and costly repairs. At HVACProSales.com, we stock a complete lineup of Drain Alert float switches, secondary pan sensors, in-line traps, and audible/visual leak alarms designed for air handlers, furnaces, and ductless mini split systems.

Engineered for fast installs and reliable performance, Drain Alert devices interrupt system operation when rising condensate is detected—stopping the unit before overflow occurs. Low-profile designs fit tight spaces, while universal wiring and field-adjustable mounts make retrofits straightforward. For service teams, these safety accessories reduce call-backs and protect ceilings, drywall, and equipment in attics, closets, and mechanical rooms.

Whether you’re commissioning new equipment or upgrading an existing system, Drain Alert delivers code-friendly protection that pairs well with routine drain maintenance and pan treatments. Add proactive leak detection to improve customer satisfaction and extend system life across residential and light-commercial applications.
