Little Giant HVAC Condensate Pump 554401 — Fixes Condensate Backup / Restores Automatic Drainage
🇺🇸 Matching U.S. Part Number: 554401 / VCMA-15ULSCondensate backing up or overflowing from your AC, furnace, or dehumidifier? In most HVAC systems, this is caused by a failed or undersized condensate pump. When it fails, water accumulates in the drain pan, triggers safety shutoffs, and can cause water damage to surrounding equipment and structure. ⚡ Common failure point in high-efficiency furnaces, central AC systems, and dehumidifiers. Part 554401 is the genuine Little Giant OEM replacement that automatically collects and pumps condensate up to 15 feet of lift, restoring safe, unattended drainage.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ QUALIFIER 1 — your HVAC appliance powers on and runs normally
- ✔ QUALIFIER 2 — heating or cooling function works correctly
- ✔ QUALIFIER 3 — drain line and tubing are clear and unobstructed
- ✔ ONLY problem is condensate not pumping out / water pooling in drain pan

🔧 Common Symptoms
- Water pooling or overflowing from the condensate drain pan
- HVAC system shutting off on safety switch (float switch triggered)
- Pump runs but water level keeps rising
- Pump is silent / not activating when water is present
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this condensate pump restores normal operation immediately.

Inspect and replace the 3/8" drain tubing and check valve at the same time — old tubing develops algae buildup and micro-cracks that cause repeat failures. Replacement tubing is inexpensive and included with this pump (20 ft).
⚙️ Installation
Skill Level: MODERATE — 30–60 minutes. Disconnect power before servicing. Remove the old pump, route the included 20' tubing to your drain point, connect the safety switch to your system's low-voltage circuit, and restore power. Snap-action float switch activates automatically when water reaches the trigger level.
✓ Compatible Models
Confirmed compatible with central air conditioning systems, high-efficiency gas furnaces, condensing boilers, dehumidifiers, refrigeration equipment, and ice machines requiring automatic condensate removal up to 15' lift at 115V. Contact us to verify your model number before ordering.
💡 Pro Tip
If your system doesn't already have a secondary float/overflow switch wired in series with the pump, add one now while you have the drain pan accessible. A $15 safety switch can prevent thousands in water damage if the pump ever fails again — and it's a 10-minute add-on during this repair.
