Here are my conclusions on this topic.. I appreciate there are preferences that differ.
DI ONLY is a simple and statistically affordable solution for times that RO does not deliver.
DI ONLY can clean to 7 storeys in all conditions.
Wash-iT PRO can clean to 3 storeys in 95% or more conditions (one operator).
Agitation CAN be achieved with tap water if you are running 2-nan crews – save demineralised water for the rinse function, rinse operator follows directly behind agitation operator.
Equally, one guy on RO, another on DI.
If there is power convenient, use a booster pump to RO for 2-men or over 3 storeys.
Amortised cost of DI annually is a better way to look at casual and intentional DI use.
A buffer tank with 2 pumps and controllers is the ultimate solution in the event On-Demand is not suitable.
