Condensate Traps

HVAC Condensate Traps

The Condensate Traps category is dedicated to the trap assemblies that make HVAC condensate drainage work correctly. A properly sized and installed trap is essential anywhere a blower is pulling air across a wet coil or drain pan. Without a trap, the fan can pull air back through the drain line, causing gurgling, poor drainage, odors, standing water and nuisance overflows. This section gives technicians the P-traps, deep traps and clear inspection traps they need to keep drains moving and airflow stable.

You’ll find standard PVC condensate P-traps, deep traps for high-static air handlers, low-profile traps for tight spaces, clear traps for visual inspection, pre-assembled trap kits and code-compliant trap designs for modern residential and light-commercial systems. Many models include integrated cleanout ports, unions or removable caps that make it easy to flush algae, debris and scale during routine maintenance. Clear-bodied traps let you confirm water seal and flow at a glance, reducing callbacks and guesswork on site.

• Standard P-traps for split systems, fan coils and air handlers.
• Deep condensate traps for high-static and negative-pressure equipment.
• Clear inspection traps for visual confirmation of flow and blockage.
• Trap kits with fittings and unions for fast, repeatable installs.
• Serviceable trap designs with caps or cleanouts for easy flushing.

When choosing a condensate trap, verify the equipment manufacturer’s recommendations, static pressure at the drain connection, drain pan outlet size, orientation and available clearance. High-static systems may require deeper traps to maintain a proper water seal, while some mini-split and coil applications benefit from compact, low-profile versions. Always install traps level and ensure they are accessible for future service.

Pro tip: Prime every new trap with water before starting the system. A dry trap will not protect against air bypass or odor migration. Add a cleanout or removable cap at the trap or immediately downstream so technicians can quickly flush the drain during seasonal tune-ups.
