system had an air gap faucet that would be running constantly (8 hours or more, I would usually turn off the water, then turn back on).

Very high quality and elegant faucet that matches out kitchen faucet perfectly. A little pricey but you get what you pay for. Not sure if I need the battery operated filter change monitor though. Note that the pure water input connector is 3/8 inch and not 1/4 inch. The drain lines in and out are 1/4 and 3/8 inch respectively. Instructions didn't say whether it could be installed as a non-air gap faucet which would have been helpful.
