The Zoeller 519-0005 condensate pump is Zoeller’s standard 115V model for replacing a failed unit or adding new condensate removal to AC systems, condensing furnaces and refrigeration equipment. It handles condensate up to 140°F and shuts down automatically in the event of an internal failure.
Key Specifications:
| Performance | 110 GPH max flow, 20 ft (6.1 m) max head; 15 ft max vertical lift |
| Electrical | 115V, 1-phase, 60 Hz, 1/30 HP motor with 6 ft grounded power cord |
| Reservoir & Inlets | 1/2-gallon (2 L) reservoir with 4 inlet options |
| Discharge | 3/8" barbed discharge with built-in check valve; handles condensate up to 140°F (60°C) |
| Dimensions | 5.6" x 7.2" x 11.5" (14.2 x 18.3 x 29.1 cm) |
Zoeller Model 519-0005 Features & Benefits:
- Built-In Overflow Safety Switch: Safety switch leads wire into a 24V Class II thermostat circuit to shut off the AC system if the reservoir overflows, protecting against water damage even when the pump has no power.
- Flexible Wall-Mount Installation: Two built-in mounting brackets and four inlet options let the Zoeller 519-0005 condensate pump mount to a wall or the side of an appliance and accept drain lines from multiple sources.
- Thermally Protected Motor: The 1/30 HP motor is thermally protected and runs on a stainless steel shaft for dependable, long-term condensate removal.
- Corrosion-Resistant Construction: Non-corrodible materials stand up to constant exposure to condensate in HVAC and refrigeration applications, and every unit is 100% factory tested.
- Easy Maintenance: The reservoir separates from the deck for cleaning, and the check valve removes with a 9/16" wrench for quick inspection.

FAQ
Q: Can I Plug the Zoeller 519-0005 Condensate Pump Into an Extension Cord?
A: No. Zoeller says not to use an extension cord with this pump. Plug it directly into a properly grounded, GFCI-protected receptacle on a constant voltage source, not a device that cycles on and off.
Q: What Size Tubing Should I Use for the Discharge Line?
A: Never use flexible tubing larger than 3/8" ID. Tubing is not included with the standard 519-0005, and Zoeller recommends a hose clamp (also not included) at the discharge fitting.
Q: How Should I Route the Discharge Line?
A: Run the line up to its highest point, then slope it continuously downward to the drain. If that isn't possible, form an inverted "U" at the highest point. Keep the highest point more than 5 ft above the floor; below that, some condensate may drain back into the reservoir, which Zoeller says is normal.
Q: Does the Pump Need to Be Level?
A: Yes. Zoeller recommends installing it level within 1/8" across its length, below the evaporator and/or furnace drain, with drain lines supported so no weight rests on the reservoir.
Q: Do I Need a Condensate Neutralizer With a Condensing Furnace?
A: Possibly. Zoeller notes that local codes may require a condensate neutralizer when this pump is used with a condensing furnace, so check your local plumbing code first.
Q: How Do I Test the Overflow Safety Switch?
A: Unplug the pump, run the appliance, and pour water into the reservoir until the appliance shuts off. Then plug the pump back in; the appliance resets once the tank empties. Full steps are in the installation manual.
Q: Is the Zoeller 519-0005 UL Listed?
A: Yes. Zoeller's spec sheet shows it is tested to UL Standard 778 and certified to CSA Standard C22.2 No. 108.
Q: What Does the Zoeller Warranty Cover?
A: It covers defects in material and workmanship from the date of purchase, with proof of purchase required. It doesn't cover damage from misuse, improper installation, unapproved disassembly, or exposure to debris, oils or corrosive substances.
Q: Is There a Lower-Profile Version for Tight Spaces?
A: Yes. Zoeller's Model 522-0005 is a low-profile condensate pump at just 5-1/8" tall, with two inlets. Contact us for pricing and availability.
NOTICE: Do not use with water that is unsafe or of unknown quality without adequate disinfection either before or after the system.

The Zoeller 519-0005 is designed for straightforward installation below your HVAC or refrigeration equipment's condensate drain and arrives ready to connect. Installation by a qualified HVAC technician or licensed electrician is recommended to ensure proper drainage, discharge routing, and electrical and safety switch connections.
Key Installation Requirements:
- Mounting location below the evaporator and/or furnace drain
- Grounded, GFCI-protected 115V receptacle within reach of the 6 ft power cord (no extension cords)
- 3/8" ID discharge tubing (not included)
- Hose clamp for the discharge connection (recommended, not included)
- 24V Class II thermostat circuit for the safety switch connection
Important Notes Before Installing the 519-0005:
- Installation must not exceed a maximum of 15 ft of vertical lift.
- Install the pump level within 1/8" across its length, and support drain lines so no weight rests on the reservoir.
- Do not use flexible tubing larger than 3/8" ID, and plug the pump into a constant voltage source, not a device that cycles on and off.
- Local codes may require a condensate neutralizer when the pump is used with a condensing furnace.
- The pump is evaluated for use with water only, and all drain and discharge plumbing must meet local codes.
- Always refer to the official Zoeller 519-0005 Spec Sheet for performance data, dimensions, and compliance information.
Basic Installation Overview:
- Place the pump below the equipment drain, or attach it to a wall or the side of the appliance using the two built-in mounting brackets.
- Cut the end of each drain line at a 45° angle and insert it through an inlet until the tip contacts the bottom of the reservoir, keeping a continuous downward slope for gravity flow.
- Connect the 3/8" ID discharge tubing to the barbed check valve, run it up to the highest point possible (ideally more than 5 ft above the floor), then slope it continuously downward to the main drain. If a downward slope isn't possible, form an inverted "U" at the highest point.
- Wire the safety switch leads into the 24V thermostat circuit so the equipment shuts off if an overflow occurs.
- With the discharge line in place, plug in the pump and pour water through an inlet until it activates.
- Test the safety switch: unplug the pump, run the appliance, and add water until the appliance shuts off. Plug the pump back in; the appliance resets once the tank empties.
