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.

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.
