GPD – Gallons of water the system can produce in a 24- hour period.
Glycerin Pressure Gauge – Monitor feed water pressure for optimal performance. It will also make pressure drops apparent which can tell you that pre-filters need to be changed out.
Dual TDS Meter – Helps monitor the TDS (total dissolved solids) in two places on the RO unit. This helps notify you of the water quality and when to change out the RO membrane & DI resin cartridges. This is the most important upgrade option for an RO/DI unit.
Water Saver – On an average an RO system wastes 3-4 gallons of water for every gallon purified. The water saver kit recycles the wastewater reducing waste by 50%. A minimum of 65 PSI is needed for optimal flow.
