Aquasana AQ-4000 has PROBLEMS...! SOLUTION!, June 19, 2006
This review is from: Aquasana undercounter water filter system (Kitchen)
I have a water well, so I do NOT want to restrict water flow to my kitchen sink faucet...!!!
As soon as I installed their AQ-4000 "sink top" model-
I noticed it took MUCH MUCH longer to fill the sink with unfiltered water (for dishes...)?!
I removed their aerator assembly..., and discovered it had a "non-removable!" VERY SMALL 5/32"..., "permanent" METAL restrictor hole!
I then installed their optional "Under-Sink Install Kit" (AQ-4056 (best), or AQ-4050 (MUCH less$)) .
This complete kit has a faucet that mounts to sink-top (NOT very easy, but worth it!- Drill 7/8" hole, mounting bracket screws are too large..., connect new water-T...)-
I now have good filtered water, and a "normal" water flow at the sink faucet! :o)
~~~~~~~~~~~~
UPDATE!- CONS (after using it for 6mo.- I'd now downgrade it to a 1 (they don't give 0!)!-
1. Changing the filters is a HASSLE! Had to work hard & gouge the down filter out with several tools (sticks BADLY!). Yes, it started leaking too!
Reverse Osmosis/distllled water has a BAD ph, and necessary minerals are removed!
2. I since got a Whirlpool UltraEase "PLUS!" under sink water filter mounting kit (Lowes only). Lines from AQ4000 fit it to the sink top faucet. They also carry sink top faucets, and filter mounting kits (in-store- couldn't find mounting kit online?).
Review the filtration specs on this NSF (govt.) approved Whirlpool "Plus" filter- lead/flouride/cysts/..., VERY impressive specs., for most home users!

Aquasana -ruin your kitchen for only 129.00, October 3, 2006
This review is from: Aquasana undercounter water filter system (Kitchen)
This unit leaks. If you install it under your sink it will surely leak and ruin the cabinets. The management of Sun Water Systems will then only tell you that it is your fault, you have bad water, or some other ridiculous comment. In reality the plastic filter housing is cheap, the threads break, the O-ring is insufficient in size to seal the unit, and the actual water quality is questionable, as evidenced by the solid scale that builds up around the faucet and the water test that produced the same results from unfiltered city water as the filtered water from the under sink unit. Bad choice for us. We invested in a RO unit with a local service team, higher specs and a proven track record of reliability. We now have to replace our sink cabinet from the damage...

Too many problems, February 11, 2008
This review is from: Aquasana undercounter water filter system (Kitchen)
Filters are much more difficult to install than I think they should be, unit consistently breaks or has a problem every few months. The white plastic filter housing has broken twice (see photo) and I've had to replace the faucet/dispenser at least once because it constantly dripped or even poured. I am now on hold to get another part since I am a "Water 4 Life" subscriber for about $100 year - which includes two filter changes and warranty. Eventually I will probably spend the time and money to get a better unit.
UPDATE 2008-11-29: After the water filter housing broke a third time, I requested that they send me another one for free which they did (no shipping charge) (I am a Water4Life customer). They seem to have redesigned this part so hopefully it will not break again.
