The flow rate corresponds to the speed at which water passes through the filters during filtration. A slower flow rate is not necessarily abnormal and depends on several factors related to installation, use and water quality.

In the majority of cases, a slow flow rate is explained by one of the following situations:

→ Insufficiently primed filters
If the filters have not been completely primed, air pockets may remain inside. This prevents water from circulating correctly.
➡️ The solution is to prime the filters again until completely saturated.

→ Partial filling of the system
When the upper chamber is only partially filled, the bottom of the filters works harder than the rest.
➡️ It is recommended to fill the upper chamber completely at each use to ensure even wear and optimal flow rate.

→ Accumulation of sediment over time
Depending on water quality, particles can accumulate on the filter surface, which gradually slows down filtration.
➡️ Simply remove the filters and gently scrub them under running water with a non-abrasive pad to restore the flow rate.

A slow flow rate is therefore generally easy to correct and does not mean the filters are defective. Simple maintenance and correct priming are sufficient in the majority of cases.
