Its enof for the working day about 150 liters over id say and with days off i should be ok but the ro has been running for 2 days straight

first 24 hours was to fill van tank to the brim 2nd 24 hours was which ended now was to fill barrles and 220l water butt so in total i have about 770 liters which is pretty much 3 days work, 1.5 to 2 days in van tank and 1.5 days in storage
i find it pretty insane that ro running like crazy for 2 days my question is does anyone els do it this way? the booter pump is running quite cool so no problems there
i think i would prefer something alot faster as im in a flat i have a garden hose going to the balconey and its a bit annoying especially over 2 days! ;p
