I just want to share kudos about this outstanding vendor. Fantastic customer service! I was just installing a Supply Valve to my house's plumbing and performed 1 step incorrectly. In a panic, I emailed AWI and they responded with the correct answer within 5 minutes! Another time, I needed a small gasket they didn't sell separately and before I knew it, they sent it to me free-of-charge. I bought a RO system from them and get my replacement cartridges and other stuff from them regularly. Air, Water & Ice is highly recommended by me!
Just doing FW for now.
