Sorry but call me dumb but how can that triple ro static system produce 37,000 litres of pure water per 24 hour period?
That's over 1,541 per hour or nearly 26 lpm (not including waste water) so that can't be right surely even using a big arse booster pump.
If that is the case will be trying to draw more water that the mains supply will allow which also my understanding is illegal to try.
