I have been having problems recently producing sufficient pure water.
I have been using a 200 GDP Reverse Osmosis filter system from Pure freedom, but this was not producing enough, roughly 220 litres per day. So I bought a second unit thinking that would double production, but because of the water pressure being effectively halved it didn't.
I also bought a pump which only managed to increase production slightly so, what could be the solution, should I buy a larger filter system and what should the water pressure be for the system to work effectively?
