First, before you replace an existing residential condensate pump, it is important you know the routing and installation of the discharge line for drainage.
Next, to ensure the pump will be suitable for your installation look at the existing pump rating and note the following key critical details:
- Input Voltage
- Flow Rate Gallons per Minute or Gallons per Hour
- Maximum Pumping Head
- Maximum Permissible Water Temperature
Finally, as along with the critical details above, you will also need to know if the existing pump has any built-in accessories, such as:
- Check Valve
- High Water Level Safety Switch
Caution – Thorough attention must be paid to these details when comparing models between different manufacturers because pumps that look seemingly identical may not have the same performance.
In the example below, the two pumps below look almost identical – but they are not.
- The Hartell A3X-115 model has a pumping head of 24ft while the alternative is pump has a pumping head of only 14ft (42% less than the A3X-115).
- The maximum flow rate of the A3X-115 is 398 GPH and the alternative is only 200 GPH (50% less than the A3X-115).
- The Hartell A3X-115 rated water temperature is 212°F where the alternative is only 120°F
