When the water output of the water purifier becomes small, we have to go through the principle of clean water and the process of clean water to understand the possible problems. The common water purifier in the market is a Water Filter Cartridges(KOKOELECTRIC) type water purifier, which filters the water quality through two or more water filter cartridges of different materials. In the process of water purification, the water enters the pipeline from the pressure barrel, booster pump and valve port of the water inlet and then is transported to the water filter cartridges for filtration. Any link in the process may be the cause of abnormal water output of the water purification device.

1. In the water inlet process of the water purifier, first of all, it is necessary to determine whether there is any problem with the water pressure of tap water. Due to the temperature drop and other reasons, the fluidity of water will slow down, resulting in smaller water output. If the water pressure is too small, it is necessary to consider adding a booster pump to boost the water supply. Check whether there is air leakage in the pressure barrel; if there is a booster pump, check whether there is any problem with the booster pump and accessories and whether the water delivery pipeline is damaged or leaking.

2. The problem of water filter cartridges is an important reason for most water outlet problems. Each layer of water filter cartridges may be blocked due to filtration problems, further resulting in small water output. Of course, the water filter cartridges are the key of the water purifier. Whether there is a blockage or not, it should be replaced regularly to ensure the quality of clean water and avoid secondary pollution.

3. The internal components of the water purifier are defective or malfunctioning, which also directly affects the water output of the water purifier. It is necessary to check whether the internal and external components of the water purifier are loose or damaged.
