Drain Alert® Condensate Safety Switches
Overflow protection that helps prevent water damage from clogged drains, blocked pans, and condensate pump failures—ideal for attics, closets, and finished spaces.
Water-damage prevention
Shuts down equipment before overflow becomes a disaster.
Fast installs
Simple placement on drains, pans, and pump circuits.
High-risk locations
Great for attics, ceilings, closets, and finished basements.
Professional protection
Adds value to installs and reduces callbacks.

Small part. Big protection.

Condensate overflows are one of the most common causes of HVAC water damage—especially in attics, closets, and finished spaces. A clogged drain, algae buildup, blocked trap, or failed pump can turn into ceiling stains and expensive repairs fast. Drain Alert® safety switches add a layer of protection by shutting down equipment (or triggering an alert, depending on application) when water reaches a critical level.

These switches are commonly used with air handlers, coil pans, secondary drain pans, and condensate pump circuits. For contractors, it’s a smart upgrade that reduces callbacks and protects the customer’s property.

If you’re not sure which switch style you need, we’ll help you choose based on the drain configuration, available clearance, and how you want the system to shut down.

Fast match-up checklist
Send: equipment type (AHU/coil), drain type (primary/secondary/pan), available space, wiring preference, and photos of the drain/pan area if possible.

Drain Alert Safety Switches — FAQs

Where should a condensate safety switch be installed?

Common locations include the primary drain line, secondary drain port, auxiliary pan, or condensate pump reservoir—depending on system layout and risk level.

Do safety switches stop the water leak?

They help prevent damage by shutting down the HVAC equipment when water rises, reducing continued condensate production until the blockage is cleared.
