## Description

Waterdrop Reverse Osmosis Alkaline Water Filter

Review: Unit was easy to install and performs as expected. Prior to installation my RO TDS was 7ppm. After installation TDS is now 27 ppm and pH is 7.8. From what I’ve read I was expecting a 20 point bump and that’s exactly what I got. Water taste is similar to some of the bottled “Smart Water” products. Both pH and TDS meters were calibrated with calibration fluids prior to test. (Leftover from planted aquarium days) I will occasionally retest to determine when replacement is required. I would be happy with 5-6 months of service. Based solely on my experience, I would recommend.
Review: the cartridge was unexpected addition to the Waterdrop G2 Reverse Osmosis system followed instructions closely but it leaked at outlet side .Made the mistake of mounting under cabinet as instruction suggested Thus could not get tubing to release when it leaked . Contacted supplier they were more. than happy to replace , promptly .Best Customer Service Customer service mailed replacement faster than desertcart's first mailing . Second install purchased more tubing from Home Depot and cut tubing long enough so I could remove from under cabinet before trying to remove cartridge and this made it easier to remove tubing following instructions, Also added duct tape to tubing when installing so had a. firmer grip pushing in tubing beyond the initial click , So far works great , City Water does taste better Very satisfied customer happy with purchase
