Proper maintenance of your RO system is imperative to ensuring system performance and extending the systems lifespan. All water filters and reverse osmosis systems need to be looked after, so it is important to follow the recommended maintenance schedule for the system. We make this easy by supplying replacement filter kits for our domestic systems, simply select the option you required based on the suggested schedule.

The filters in the PRF RO system are easy to change, the triangular support leg is also a spanner that can be used to help undo the housings if they are tight. When you have changed the filters the bowls should only be hand tightened. Remember to order two replacement membranes if both require changing.

How Often Do I Need To Replace The Filters In The Pentair PRF RO System?
The carbon pre and post-filters should be changed every six months. The RO membranes should be replaced when you notice a slower flow rate or a change in the water quality; with soft water you can expect the membranes to last 2-3 years or with hard water around 1-2 years.
