Do You Need a New Condensate Pump?

Published: 07 Feb 2025 ・ Read time: 6 Mins

Condensate pumps play a crucial role in maintaining the efficiency of HVAC systems, especially in removing excess water that accumulates during the cooling process.

Over time though, these pumps may wear out or become faulty, leading to potential issues with your system. There are several signs that indicate you may need a new condensate pump.

Here at City Plumbing, the home of heating, we take a look at what condensate pumps are, highlighting the importance of a timely replacement, while considering if it's time to replace your current one.

What Are Condensate Pumps?

A condensate pump is a clever device designed to remove acidic wastewater, known as condensate, which is produced by modern condensing boilers and other appliances like air conditioners, refrigeration units, and dehumidifiers.

Do I Need a Condensate Pump?

There are a few reasons why condensate pumps need replacing. The most common is concerning acidic condensate. Condensing boilers generate condensate which is acidic and can corrode pipes and damage the environment if not disposed of properly.

The other issue concerns drainage issues. Often, the location of the boiler or appliance is far from a drain or below the level of the drainage system, making gravity drainage impossible.

The replacement of a condensate pump will also depend on your boiler type. If you have a modern condensing boiler, it produces condensate as a byproduct of its efficient operation. This condensate is acidic and needs to be disposed of properly. Those older, non-condensing boilers do not produce significant amounts of condensate.

How Do Condensate Pumps Work?

Collection: The condensate is collected in a reservoir within the pump.
Pumping: When the reservoir reaches a certain level, the pump activates.
Discharge: The pump propels the condensate through a narrow pipe to a suitable drainage point, which could be a wastewater pipe or a dedicated condensate drain.

What Types of Condensate Pumps Are Available?

Tank Pumps: These have a built-in tank to collect the condensate before pumping. They are suitable for situations where the condensate volume is relatively low.
Mini Pumps: These are compact pumps designed for installations with limited space. They are often used with air conditioners and refrigeration units.
High-Lift Pumps: These pumps are designed to pump condensate over greater vertical distances, making them suitable for installations where the drainage point is significantly higher than the appliance.

What to Consider Before Purchasing a Condensate Pump:

Pumping Height: The maximum vertical distance the pump can lift the condensate.
Flow Rate: The volume of condensate the pump can handle per hour.
Tank Capacity: The size of the reservoir in tank pumps.
Noise Level: How loud the pump operates.
Power Consumption: The amount of electricity the pump uses.
Installation: How easy it is to install the pump.

Important Considerations:

UK Regulations: In the UK, it's crucial to follow regulations regarding condensate disposal. This often involves neutralising the acidic condensate before it enters the drainage system.
Professional Installation: It's recommended to have a qualified plumber or heating engineer install the condensate pump to ensure it's done correctly and complies with all regulations.
