Although gravity drain has historically been used to remove condensate water from air conditioning units, it is not the most effective as it can pose health and safety risks. Furthermore, installing a gravity drain system as an afterthought idea can be very tricky especially in space restricted areas. To deal with the challenges posed by gravity drain systems while attaining greater comfort at homes, the AC industry prefers the use condensate removal pumps. The installation of condensate pumps adds flexibility as they eliminate the need for gravity allowing their use irrespective of the application whether in a flat or in the basement. However, despite being the ideal solution, it is worth noting that some condensate removal pumps brands and models are of superior quality. Some of the top 10 best condensate removal pumps in 2019 that you should consider include:

Tips on how to choose the best condensate removal pumps
To choose the best condensate removal pump, you must first understand the application including handling and disposal regulations. You should also figure out the lift requirement for the pump by locating where the pump will be mounted as well as the location of the discharge point. The condensate flow will decrease based on the height it will travel until the shut-off or the maximum lift is reached.
Before purchase, you should check the lift rating to ensure that the specific pump is suitable for your application. The right pump should also offer output flow that is at least twice the input rate. Other things you should consider include the voltage requirements, power cord and plug long enough for your application, a safety switch, a thermal overload protection and a stainless steel shaft. It is also important to note that units with UL and CSA certification guarantee safety.
It is necessary that the condensate water in your air-conditioning system gets drained out to prevent the piping from cracking or even cause improper functioning of your system. The above 10 condensate removal pumps are rated as the best in 2019 with greater flexibility and functionality. They are also designed for safety with useful features such as a check valve, a thermal overload protection and a safety switch. The tanks are also big enough for everyday use. The units also come with long power cords for greater flexibility and powerful motors for better removal. The pumps can also be used in a wide range of applications as they are well designed to handle the high temperature and contaminants common on condensate water.
