 I live in kent and have a tap TDS of 310 which my r/o man 200gpd pumped system gets down to 8 then my DI dose the rest to 0.
So just wondering if a 4040 RO would get it down more befor DI as i was told that a high pressure 4040 would do so?
Is this true and what could the end result be?

any ifo would be good

thanks joe

a good 4040 on sufficient pressure would most likely bring the tds down to something similar, the real advantage of a 4040 is its ability to produce lots of water, they last a lot longer too if looked after.

i use a 4040 and i get it down to between 10 and 11 from 320 ish so its quite reasonable and the production rate is very good.

thanks guys but are yours the high pressure or low pressure 4040 RO membrane?
