Hi Guys, I'm new to this but basically I'm ex Royal Navy looking to start my own business and I've been doing abit of research via the usually channels i.e you tube, tiktok etc. Anyway I'm just wondering about the water waste in converting to pure, now I'm not a massive tree hugger but I do like to do my bit and I've read that for every 1 litres of pure there's roughly 5 litres of wate. Now I'm just wondering is there any reason why you can't have say 2 350 litre tanks, one as a feeder header tank feeding the pure but the waste going back into the header tank rather than down the drain? Sorry if this is a stuppid question but my previous occupation was military satellites so I'm on abit of a learning curve. Cheers all.
