Water filtration systems are designed to be used on continous use. Taken out of service (shutdown) for an extended period of time, there may be impacts to product performance. Please click on the appropriate image and follow the instructions in the PDF to ensure consistent performance when the system is returned to normal operation.
BWT has a full range of professional water filters including the Bestmax cartridges and it is important that you download and follow the instructions in the leaflet ‘Preparing your water treatment equipment after closedown‘.
Reverse Osmosis equipment – restart after shutdown
- BWT bestaqua 20 range – 22/24/26
- BWT La Marzocco Osmo range – 60/120
- BWT bestaqua ROC 14
- BWT bestaqua ROC 14 coffee
During extended shutdown, without power, the automatic flushing facility is disabled. For reasons of hygiene, and long-term membrane effectiveness, it is not advisable for membrane(s) to be in contact with standing water for an extended time. BWT best practice advice is to replace the membrane(s).
With careful maintenance, it may be possible to delay membrane replacement.
After extended shutdown, membrane(s) needs to be flushed with about 40 litres of raw water. This will take between 10 and 25 minutes, depending on the model Whilst flushing, it is essential to monitor flow rate and conductivity.
If both measurements return to pre-lockdown levels, the membrane is unharmed and the unit is suitable for normal service. However, if either flow rate, or conductivity are consistently below 80% of pre-shutdown rates, membranes need replacing.
Please order replacement membranes through your normal supplier or contact us for advice by email at firstname.lastname@example.org.
Ensuring equipment is restarted correctly
Flushing water filters is required
To help BSA Member customers manage the procedure themselves, which may help to take the strain from BSA Member engineers, please see the information below.

Maintenance & Service work
Capital expenditure will be under pressure as budgets are squeezed, but maintenance/service work should increase.
- To prompt this, the end user/operators must be aware of the importance of preventative maintenance on their equipment, which of course includes replacing the filter cartridges on time to prevent scale related damage and improve the quality of their water to create the best end products.
