thats the one bud... 2 pumps= 1 for each 200gpd membrane.
there are 3 10" standard pre filters like any other RO. i didnt want a di cannister, i use a small 6x18 DI vessel after RO. but he will set it up for you if you wanted a built in DI instead, i think he replaces one of the prefilters.
it is manual flush. all that means is that every now and again you turn the blue tap that you can see below the rear membrane and just let it flush through for half hour or so.
the pumps are 100psi each and work a treat. you'll need a plug point nearby, and the transformers are not designed to run all day, they get warm, so to look after them he puts in a timer plug and sets it to switchoff every 90mins for 30mins.
i have ok water pressure but it doesn't blow the taps off, thats what the pumps are for, membranes work better with high pressure, produce more and lower ppm.
the membranes run in parallel as this produces quicker hence 1 pump each, this however produces a higher waste,
so it can be set up to run in series, this would mean 1 pump for 2 membranes, it wont produce as fast but the waste is lower.
IMO i dont think it makes alot of waste anyway, i have mine going down the washing machine drain and when i looked how much goes down, it was only a trickle. might be more concerned if i was on a meter. but hey...
i use 300ish litres a day. and use a trolley, i fill 6x25ltr containers to the brim so nearer 30ltrs, i come back and top up at dinner, and the 210butt is full. it fills it in about 3hrs.
