RO The Loft

[Pondwater]

So 200litre tank in my loft.
Change 1nce a week.

The ro filter at my mates seems frwaking impossible to get in my loft.. Preassure and measly flow......

So
How do you ro ur loft.
Seen these ros from growmax 200quid 2000gpd and a aito shutoff when it reaches the max tank line...

So how do i do it hmm
Upstairs toilet has a sink i fill from 400ppm.
I run a hose into the loft and shout when she needs to turn it off.

Can i put a ro on this here? Like hose into loft and ro filter thete or will the preassure be too low? They say they require 30psi ive no idea what psi is up there.
It fills 200l tank in around 15 mins

25 PSI relates to about 2 liters per minute, slow filtration and the pressure on sediments inside the filters is important to prevent backwash and stuff.
My weekly water need is about half of yours, for me to build a cheap RO filtration system with chloramine removal would be about 400$ installed so I decided to do it another way.
I use a water dispenser filtration unit that uses two filters like "double barrel" filtration, dual airstone and a pump to dispense where I wired an old switch to the pump (see pic) can easily get 200 liters a week from this on the cheap
