Filtration systems are designed to be operated on a continuous basis with only relatively short periods of downtime. When a system is shut down for an extended period of time, there is a potential for microbiological growth. To address concerns with system operation after the shutdown, follow the below instructions. This is applicable to all Pentair filtration systems (i.e. pre-filters, carbon-based cartridges and RO systems.)

General Water Filter Cartridges Best Practice
If your system does not currently utilise Pentair water filter cartridges there are also some general best practices to keep in mind with any filtered water system. We always recommend carrying out any procedures in a sanitary fashion and encourage users to consult manufacturer's guidelines when considering any planned preventative and reactive maintenance practices.
Downtime of 36-48 hours
Short term, 36 - 48 hours without operation, the cartridge should be flushed with a minimum of 5 litres of water. This is mainly to clear bacteria build up as short term changes in temperature / exposure to light can affect all manner of things such as taste and odour.
Downtime of over 4 Weeks
After a break in operation of 4 weeks or more the cartridge should be replaced. Bacteria / toxins that could be harmful to consume will have likely multiplied over this period.
It is always recommended to sanitise the lines as frequently as possible, regularly sanitising kills most of the bacteria that form on surfaces.
Reverse Osmosis Systems
We advise to run these units every other day to keep the membranes fresh and primed and to ensure that any water in the tank is used to prevent bacteria build-up. Sanitise the lines as frequently as possible and check your tank pressures and re-pressurise if appropriate as under-pressurised tanks affect the performance of the system.
Over 4 Weeks
After a break in operation of 4 weeks or more, the membranes should be replaced along with any pre and post-filtration. Bacteria / toxins that could be harmful to consume will have likely multiplied in this time and could be dangerous to consume, along with affecting the taste and odour of the final beverage.
With the above information in mind we have been busy ensuring we have everything you and your customers will need to restart equipment safely from replacement cartridges to safe, hygienic areas. We have put together hygiene kits and antibacterial wipes to clean and protect from bacteria and viruses.
