Revers Osmosis System Advice Needed

[Ross]

Becca, how many plants do you water? A 5-gallon pail or two should do most modest collections. There's a little misinformation here (or really poor specs). The membrane should rarely be replaced. the filters should not need changing more frequently then annually. My water runs through a whole house softener before it gets to the RO unit so the RO unit needs to remove all the sodium in solution. I have yet to need a new membrane and I push the unit to deliver a minimum of 4 gallons per day but often I draw 7-10 gallons per day. The filters get replaced annually for free and the technician checks the "rejection rate" which is how much solids are being rejected in the water. Mine runs 97-98% rejection which is excellent. By the way, the big tank under your sink cannot fill completely with water because there is an air bladder in there pressurized to push the water up to the faucet. As the tank fills it compresses the bladder which then serves as water pressure. That's why it dribbles out toward the end of drawing the water.
