Regular servicing of your RO water purifier is essential to maintain water quality and prevent filter clogging. Ideally, service should be done every few months, but frequency can vary depending on water hardness and daily usage. Look out for warning signs like a drop in water flow, unusual taste, or error indicators on the unit. Pre-filters often need more frequent checks, while the RO membrane typically lasts longer. Always keep track of the last service date and replace filters as per the recommended timeline. Cleaning the external body and storage tank regularly also helps prevent bacterial growth. Timely servicing not only ensures safe drinking water but also avoids costly repairs caused by neglected maintenance. For more information, https://www.lg.com/in/water-purifiers/
