Anyone involved in the everyday use of common appliances like refrigerators, furnaces, and air conditioners has unidentified experience with condensate pumps. The need to drain water produced by the operation of various appliances necessitates the use of a condensate pump. Without one, the vapor accumulated by these appliances would cause dysfunction.
Choosing a condensate pump is a more intricate process than you might expect. In this article, we will explain their inner workings, how to handle them properly, and teach you what features to pinpoint in your search for the best condensate pump
What is a Condensate Pump?
Let’s go back to basics. Before you can begin your search for the best condensate pump, you need to have a firm understanding of what it is you’re searching for.
A condensate pump is required as part of any heating, ventilation, or air conditioning (HVAC) system. Condensate pumps are centrifugal pumps, meaning that they transfer energy to fluids resulting in strong pressure and momentum which pushes the fluid in the designated direction.
Condensate pumps take their name from the fluid which they push – the water from condensed steam produced by the specific appliance.
How Do Condensate Pumps Work?
HVAC appliances accumulate water as they operate and this water needs to be drained in order to maintain proper functioning. This is the condensate pump’s job.
Condensate pumps function so that when accumulated water reaches a certain level, the pump is activated. The pump’s motor turns on, and water is suctioned into the impeller, which drains the water by rotating. Picture a miniature propeller.
While many HVAC systems are designed so that the condensate pump filters water to an outside drain, not all are made this way. In steam systems, the condensate pump sends the water to another area to be cleaned and is then recycled back to the steam area.
When Should I Replace a Condensate Pump?
It’s easy to forget about the condensate pumps in your appliances, but like many appliance parts, condensate pumps sometimes need to be replaced.
It’s not likely that you’ll need to replace your pump too often. However, you’ll know when your condensate pump is not working. Over time, your condensate pump’s motor may start to fail, or the switch which turns the pump on and off may become worn due to accumulating dirt and debris.
The most obvious sign that you need a replacement is when your condensate pump is leaking. You’ll notice small puddles of water on the floor or surface areas near the specific appliance.
Can I Replace a Condensate Pump By Myself?
Considering doing it yourself? Go for it! The truth is that if you can follow directions, you’ll be able to replace your condensate pump without help from a technician.
Here’s what I mean: the condensate pump installation process is not particularly difficult. You do need to know how to unfasten and refasten screws and pay attention to the positioning of electrical wiring. If you feel capable of these things, then there’s no reason you can’t change a condensate pump yourself.
No pressure though. You can always hire a handyman to help you out!
What Features Should I Search For in a Condensate Pump?
The best condensate pumps have various features which enhance their functionality. Here is a short list of features to look for in a condensate pump:
- Pump Head Measurement: This tells you the maximum height to which the condensate pump can deliver a liquid to the pump outlet.
- GPM/GPH: GPM or GPH refers to the gallons of condensate water which the pump can remove in one minute or hour. You want a pump that can remove 2-3 times the system’s input condensing rate.
- Voltage: Most standard household appliances require 115 or 120v. Some larger appliances require 230v, and commercial grade appliances may require as high as 460v.
- Horsepower: Typical household appliances generally range from 1/30hp to 1/50hp.
Before you invest in a new condensate pump, be sure to examine your appliance for specifications about these features to ensure proper and optimal functioning.
