- Shut Off the Power
Locate the furnace’s dedicated power switch (usually mounted on the side of the unit or nearby wall) and flip it to “off.” If you can’t find it, turn off the breaker in your electrical panel labeled for the furnace.
- Stop the Water Flow
If the leak appears to be coming from a connected humidifier or water line, shut off the valve supplying water to that component.
- Mop Up Standing Water
Use towels or a wet vacuum to remove water from the floor. This prevents damage to flooring, reduces slip hazards, and helps you see exactly where the leak is coming from.
- Check Your Sump Pump
Depew basements often have sump pumps due to the area’s clay soil and high water table. Make sure your sump pump is working to handle any additional water.
- Call for Emergency Service

5 Common Causes of Furnace Leaks in Depew Homes
Understanding what’s causing your furnace to leak helps you explain the problem to your technician and can give you peace of mind about the urgency. Here are the five most common culprits we see in Depew basements:
| Cause | Common in Depew? | Urgency Level | Typical Repair Time |
|---|---|---|---|
| Clogged Condensate Drain Line | Yes – High-efficiency furnaces common | Medium – Can wait a few hours | 1-2 hours |
| Faulty Humidifier | Yes – Hard water causes mineral buildup | Low – Not an immediate safety issue | 2-3 hours |
| Cracked Heat Exchanger | Possible – Age and corrosion factors | High – Carbon monoxide risk | 4-6 hours (often requires replacement) |
| AC Coil Drain Pan Issues | Seasonal – During cooling months | Medium – Water damage risk | 2-3 hours |
| Failed Condensate Pump | Yes – Many Depew homes need pumps | High – Water will continue leaking | 1-2 hours |
Why High-Efficiency Furnaces Leak Water
Depew homes built in the last 20 years likely have high-efficiency furnaces (90% AFUE or higher). These units are fantastic for energy savings but have a unique plumbing system that can fail in Western New York’s harsh climate.
High-efficiency furnaces extract so much heat from combustion that water vapor in the exhaust condenses into liquid. This acidic condensate flows through a white PVC drain pipe to a floor drain or condensate pump. When this system fails, water ends up on your basement floor.
Common failure points in Depew include:
- Frozen intake/exhaust pipes – Buffalo’s sub-zero temperatures can freeze these PVC pipes, causing pressure buildup and leaks inside the furnace cabinet.
- Clogged drain traps – Erie County’s hard water creates mineral deposits that block the P-trap, causing water to back up and overflow.
- Failed condensate pump – Many Depew basements sit below the main floor drain level, requiring a pump. When these fail, water has nowhere to go but out.
During our diagnostic process, we use a manometer to test the pressure switch and ensure proper venting. A reading outside the manufacturer’s specifications (typically 0.5-1.5 inches of water column for most 90%+ furnaces) indicates venting problems that need immediate attention.
