Inspecting Drain Lines
While they may seem simple, drain lines (or condensate lines) are critical for preventing water damage. Their job is to safely carry away the condensation that forms on the cold evaporator coil during the cooling process.
Drain Line Inspection
Improperly installed or damaged drain lines are a leading cause of roof and interior water leaks, especially during summer when units run for long periods.
What to Look For
- Proper Termination The drain line should run from the unit directly into an approved receptacle, such as a roof drain. This ensures water is channeled away correctly.
Common Problems & Red Flags
- Missing Drain Lines Some units may have no drain line at all, allowing water to pool around the unit, which can damage the roof over time.
- Cracked or Broken Lines PVC drain lines can become brittle from sun exposure. Look for cracks or breaks that will cause leaks.
- Improper Termination A line that simply ends and drains onto the roof surface is a major red flag. This can lead to ponding water, roof degradation, and eventual leaks into the building.
Pro Tip: A Small Fix Prevents a Big Problem
Drain line issues are often inexpensive to fix but can cause thousands of dollars in water damage if ignored. This makes it one of the most cost-effective checkpoints during an inspection.
