What does free flow from RO tap mean in practice?
In a system with a tank, it is mainly responsible for the pressure and amount of water in the tank, as well as the patency of the post-filter and the hose.

Low membrane efficiency and poor flow from a full tank are two different service problems.
Which solutions are related to it?
Measure the amount of water in the tank, the pressure of the air bag after deflation and the flow before and after the post-filter.
