New Reverse Osmosis Water Purifier with Tank and Pump, 7-Stage 75 Gallon RO Pure Water This is a brand new, unused under-sink reverse osmosis water purifier. It's a 7-stage, 75-gallon high-end model. It has 7 filters and a pump capacity of 75 gallons per minute. It's more than enough performance for home use. I think it's also sufficient for commercial use in small businesses. For example, cafes and restaurants. It has been opened for photography. All filters, tank, tubes, faucet, branching equipment, tools, etc. are included. It comes with an electric pump. I am a novice, but I was able to install a product from the same manufacturer myself. I occasionally measure with a TDS meter, and it consistently produces pure water. ◎ I am selling this because I was able to use a similar product. (The pump is 100V compatible) No claims or returns accepted. We will respond within 7 days of the arrival date. I believe this is the lowest price for a reverse osmosis water purifier on the market.
