RO water sources in No VA?

[sen5241b]

Many of the Whole Foods stores including the Vienna and Tysons stores have the RO filter machines. The one in Arlington does not. Anybody know of RO water sources in the Arlington, McLean area?

Prior to buying an RO/DI filter, I was buying my water from Pristine Aquariums. They are next to the Home Depot on South Picket. The big problem with going there was that I ended up buying more than water (at 50 cents a gallon). The good thing is that, even though they aren't a sponser, they still give a 10% discount for WAMAS members.
