If you have the more traditional Premier RO system — the larger cartridge system that can take over an hour to replace, you might wish to consider switching to this newer system. Especially if you have it installed in a confined space such as under a kitchen sink! I had a plumber do the reinstall which took him a good hour to do. Wouldn’t attempt this if you are not familiar with plumbing. Also, as there is no motor attached, you will need to rely on straight water pressure. Took a leap of faith that a 20 ft. run to the fridge water dispenser would not be too long and that water pressure alone would be enough. Glad to say it works o.k. — although the tank doesn’t refill as fast. Not a problem though, I have found, if there are time gaps between when you need to use the fridge water dispenser. Used the newer system for over a year now. Works well and now spend only five minutes swapping our cartridges when the Premier schedule requires it. Very pleased overall!
