what make ro do you have there is a 20 inch one with filters on a frame in the cleaning spot catalog does 200l an hour does that use less waste it cost £720 is that just a waste of money
if you plan to use 400 L a day, you will make your water in 2 hours, isnt that a bit of overkill
i personally think that this is the area people are often oversold on,
you think you will use 400 L a day ( yes on the odd occasions it might be more, we will say the average window cleaner uses 400 L, some use 200 , some use 600 )
personally i cannot see the need for a RO to make more than you need per day, infact when you have storage ( be it a 1000 or 600 IBC or 2 X 210 rain water butt ) i cannot see the point of a RO of over 450 L per day
you start the week with a full 400 L tank, and 420 + L of water, you replace more than you use every day ( even taking into account a 450 L will produce less than the full 450 L, we will say 400 L a day )
i really cannot see the point of anything over 450 L a day, its 230 quid, which is a great price
if you find yourself using much more, just add another rainwater butt , so you start the week with a full 400 L in the van and 630 L in the rainwater butt, of course if you have a 1000 or 600 L IBC, you start the week with a much bigger headstart, i only say about 210 L rainwater butts as they look acceptable down the side of any house ( where as i think a 1000 IBC doesnt )
230 quid, you cannot complain about that
