Please Note: RO Membranes are tested by manufacturer at 77 F Temp, 60 PSI Water Pressure, 250 PPM. For Example a 35 GPD at  77 F Degree & 60 psi water pressure and less than 500 PPM can produce 1.4 Gallon per hour. Please understand that to make 1.4 Gallon water it will be low flow (trickle). For every 1 F Degree lower temp it will produce 2% less product water. For better flow select higher GPD Membrane.

GPD means Gallon Per Day, the higher the GPD the higher the flow.

Please flush the system for 30 minutes prior to use.

Unit Comes Fully assembled, install your faucet diverter to your standard sink faucet by replacing aerator, flush till carbon fines are cleared.
