Anyone use there equipment to purify their water? Looking at getting a static system now, seems pretty reasonable. Its the 900-2000 GPD one.

i have a 300gpd ro man... brill... takes 4 hours to fill 250 litre tank... but your going for the big stuff, im only a small fry.

I only want to fill 1000 litre tank, tds is 420 ish and pressure is very poor, and the 900-2000 gpd is what they have recommended to me?

Didnt know if it was something to do with the tds??

Hi niceandclean

I would imagine that the reason is due to your very high (420) tds.  This means that on a smaller system the nonadjustable waste ratio would allow your membranes to foul up very quickly.  The advantage of a 4040 system as they have recommended is that you can adjust the waste ratio so that your membrane receives a greater flow of waste water past it.  This, along with regular flushing (5-10 mins per tank fill), will ensure that you get a decent life out of the large membrane.
