After some advice please, had a ro a couple of years ago which produced around 100 liters a day it was pretty useless. looking to get another one only need to produce around 200 liters a week, spoken to john hewitt he recommended a 200 gpd ro with another membrane for the first lot of waste water to go back into because i am on a water meter. With a di and booster pump it came to about £160, not sure if i need all this for 200 liters a week? Any advice guys

its a headache but i was going to say a merlin
or 4040 till i re read yr post doh
merlin will make your water fast
but it wastes quite a bit also

on his redhat diving website he has a 100gpd at £82 and a refillable di for £25 i think this would meet my 200 litres a week. does the 100gpd use more water than say a 300gpd?

it wud be very slow m8

 100 litre :Slow with a lot of waste water.Putting more than one membrane in series reuses the waste water therefore using less water and more water produced.

So my first example with 2 membranes might be more expensive but would save me money on my water meter. Would the booster pump save any water usage or just speed up production
