Homeowner Approved!
Most homeowners forget to add treatment to their condensate drain lines.
Drain Therapy™ continuously conditions your condensate drain to help reduce organic buildup and keep water flowing freely.
Drain Therapy™ – Automatic Condensate Drain Line Treatment
Keep your HVAC condensate drain flowing with Drain Therapy™, an automatic slow-drip treatment system designed to help reduce organic buildup before it becomes a costly drain clog. The easy-to-install hanging bag continuously dispenses treatment into your condensate drain line, helping maintain proper drainage for up to 6 months.
Unlike tablets that dissolve in the drain pan, Drain Therapy™ provides a steady, controlled application directly into the drain line. This helps reduce service calls, prevent nuisance float switch shutdowns, and minimize the risk of water damage caused by clogged condensate drains.
