The average lifetime of 10 years in indicative and is intended to raise user awareness on the need to maintain their BIOROCK system regularly.
We have units that have been in operation for over 20 years in northern Europe, and are still operating extremely well with the original bags. As a consequence, we know that with effective monitoring, the lifetime of the bags may be longer than 10 years.
The mineral-based media is an inert material, it does not deteriorate over time and retains its characteristics if the system is well maintained.
However, if system maintenance is neglected and accidental pollution has implications on the purification efficiency of the treatment unit, you will almost certainly need to change the media bags as soon as possible. We recommend that you call upon the services of a professional. The cost for replacing the media bags is currently estimated at approximately GBP 700 for a 6PE system.
