The goods were well packed. It is very good. I bought this as Brs Ro/Di systems come with this brand. I connected correctly. Water enters line 1, wastewater enters line 2, purified water exits line 3. I get 70 on line 1, 35 on line 2, 0 on line 3. Lines 1 and 2 should be in reverse order. No fewer TDS can leave the membrane than enter. It works fine and I assume it is correct. If the lines didn't change I would give 5 stars.
