Happy Customer! Our water in LEE COUNTY, FL finally tastes OK and doesn`t give me GI issues. Enough on that but after many years of unsuccessfully trying water pitcher and refrigerator filters the Waterdrop 800 with UV sterilizer has finally cut off my dependence on bottled water. Hard to believe it but very satisfied. Given the high TDS at our tap I can only hope that the filters will last long enough to make this system cost effective. If so it was worth the $$ and the effort to install an electrical outlet under the sink and to drill a hole in the granite counter top!
We've been using the G3P800 for almost a month now and it's been good. I installed the unit in the basement below our kitchen island sink to keep the cabinet clear for storage and because the unit is a bit noisy. I installed the PMT small pressure tank kit which enables instant water at the faucet about 8 feet horizontally and 6 or 7 feet up. It also allows constant pressure to the icemaker almost 30 feet away which gives us mostly clear hard ice. I would give five stars, but the unit comes up short in a few areas. For one, it should include a small pressure tank built in for the price which would simplify the installation further. It should at least include the kit.
Another issue is that the LLDPE tubing leaves an undesirable "hose" taste when the water is sitting, especially first thing in the morning. It's not a big deal to run the faucet for a couple of second to clear the 1/4" tubing and "hose" taste, but our ice always has a slightly stale taste since the line to the ice freezer can't be cleared first. Copper tubing is a no-no for acidic RO water and a charcoal filter may help mitigate the slightly off tase, but our freezer doesn't have a built-in filter.
Finally, it's inexcusable that Waterdrop doesn't make a faucet in anything other than the included brushed nickel or special-order black. Really? The faucet is very nice (but contemporary) and seems well constructed, but our home has traditional polished chrome. Why not offer a polished finish? Instead, we opted for an inexpensive and much smaller traditional polished chrome RO faucet from Amazon that only required a half inch hole. It works great but doesn't show the filtration info. Regardless, even if Waterdrop provided a polished chrome finish, their short cable wouldn't have reached the faucet since Waterdrop assumes everyone is installing the unit right under the sink.
One last thing to note is that the TDS does settle downward after a few days of use like Waterdrop support says. Our TDS was taken down from approximately 300 ppm to 43 ppm and has settled in between 18 and 19 ppm after a few weeks - a roughly 92% to 94% TDS reduction.
Waterdrop, please offer the faucet in polished chrome and offer a longer data cable! The G3P800 would be a 5-star RO filtration system for sure.
