Many homes are now equipped with drinking fountains . However, because of the constant air ingress during the drinking process of bottled water, it is inevitable that dust and microorganisms will be brought into the water. In order to ensure drinking pure and sanitary drinking water, the drinking fountains must be cleaned and disinfected frequently.

　　Under normal circumstances, the cleaning and disinfection of drinking fountains is generally twice a month in summer and once every one or two months in winter. Disinfection of the water dispenser can be done by a professional from a barreled drinking water manufacturer or by yourself. If you are disinfecting yourself, you can follow the steps below: Step 1: Turn off the power, first open the drain pipe behind the water dispenser to drain the remaining water. Because the remaining water in the sewage pipe is the key to the secondary pollution of the drinking fountain, and then turn on all the drinking water switches to release the water. Step 2: Use tweezers to grip the alcohol cotton, and carefully scrub the inner and outer sides of the inner and outer sides of the water dispenser and lid. Step 3: Prepare the disinfectant into 3000-5000ml disinfectant water according to the instructions for use, then fill the entire cavity and leave it for 10-15 minutes. Step 4: Turn on all the switches of the water dispenser, including the sewage pipe and the drinking water switch, and drain the disinfectant.

　　After the water dispenser has been disinfected, there may still be traces of disinfectant residue, so you should not drink it immediately. Be sure to use 7-8 liters of water to continuously rinse the entire water dispenser cavity, otherwise, the disinfectant residue will become a new source of water pollution. After disinfection, scrub the back wall of the switch with alcohol cotton. When using a cup to catch water, it is easy to touch the back wall of the water dispenser switch, so you can't wipe it with a rag, otherwise bacteria will get on the cup and be drunk.
