Our reverse osmosis system was serviced by the company that installed it, obviously at a much higher cost than we could have done it ourselves. This was our first membrane replacement but with a little help from a YouTube video it was easy to do. We adjusted the size (if you change the size of the membrane you get a flow restrictor of the right size, easy to change also using the video) and are very happy with it.
