This listing is for a like new open box Waterdrop G3 Reverse Osmosis Water Filter System. This system was used for display purposes in a model home. The faucet was mounted on a sink, but never connected to any water source or the system. The main unit was never used.The water filters and some accessories are still factory sealed. The listing includes all items in the photos. To my knowledge, all accessories and installation hardware is included, except for an o-ring and maybe an additional ring for mounting the faucet which may have been lost during removal. This listing is for what you see in the photos, as is.
